Group buy: Carbon fibre 1 peice tailshafts from Geforce1320

[VooDoo]

Anyone interesting in these? IM going to bring some in soon so let me know to save on shipping etc. Cost is around $1200US but Mr Geforce will look after us if we have a few orders. Can bring in some rear driveshafts, Stubb axles (inner and outer) as well if needed. Post here to we can get some idea of numbers.

I am proud to announce that we now offer a 1-piece 3.75” carbon fiber driveshaft for the GTO.

Finally a driveshaft and billet pinion yoke designed specificaly for the GTO that will eliminate all adapters, flanges and drive plates.
The billet pinion flange bolts directly to the big 1350 u-joints, no cutting of the pinion gear required either.

We have teamed up with Precision Shaft Technologies in Florida to make our driveshafts.
PST has one of the best warranties and customer service records in the business.

Our carbon fiber driveshaft is the only driveshaft on the market specifically designed for the GTO that is SFI certified :)

The warranty is simple, if there is a problem we will stand behind the product 100% and fix the problem.

The big carbon fiber driveshaft is what I run in the Gforce1320 GTO and is also what TrakDay runs in his GTO.
I think both our track times prove hands down that it will hold up to anything you can throw at it.

I truly believe the reason I have been able to run the #’s I have run without breaking very many parts is the shock absorption of the carbon fiber driveshaft.

Some C/F shaft facts:
· They run smooth as silk, no vibrations at all. They eliminate or dampen high speed vibrations.
· Lighter than steel or aluminum, lighter than anything on the market.
· Three times the torsional strength of steel.
· Torsional spring rate allows for better tire hook-up.
· Less shock load to the differential.
· Reduces drive line parts breakage.
· A better 60 ft.
· ET’s gains of at least 1 tenth are normal.
· Dyno tested to 180mph with no vibrations.
· They will safely spin to 10,000+ rpms.
· They have been SFI tested to 2800 ft/lbs of torque.
· They have a much greater safety factor, carbon fiber will return to a fiber and not create shrapnel under the car as would aluminum or steel driveshafts.

We are also offering a 3.5” and 4.0" aluminum driveshaft.

The driveshafts will come ready to bolt in with a new slip yoke for the transmission and they will also come with a new 4340 billet pinion yoke and all hardware.

I’m in the process of getting the billet pinion yokes made. I don’t believe in running adapter rings if you don’t have to.

Pricing will be:
$1199. for the Carbon Fiber shaft
$899. for the Aluminum shafts

You can purchase the shafts on our web site www.shop.gforce1320.com

Both will come with our new billet pinion yoke that will bolt directly to the driveshaft without having to cut the tip off the pinion gear and no more spacers or adapters AKA drive plates.

[raven ute]

does he make them to suit vy/vz ute with center bearing

[VooDoo]

Its pretty hard to make a 1 peice shaft with a center bearing.

[GTS Listy]

I have chased up the single piece tailshaft before but will these fit the sedans VT to VZ. Some say no and some have the BMR ones fitted to their sedans.

I would be interested definitively in the carbon fibre one, but I would need to know 100% that they will fit the sedans. i.e. the VX GTS.

How cool do they look but

[Justin]

Oooh I wish I could get me one of these. Anybody want a BMR 1 piece shaft :D

[seedyrom]

My interested is now expressed.

Though looking under the car today, I'm confused as to how it will fit.

Will post pics/queries tomorrow

[VooDoo]

If someone can measure their sedan tailshaft ill send the info to Chris. Ill measure my GTO one too and post here. Measure from the faces of the yoke's. ie donut to donut.

[GTS Listy]

Love to help but I dont have a car yet. Hope they fit. Just have to make sure the measurement is accurate as. Get those photos too which should help

[Justin]

I have the BMR unit fitted to my VX sedan. Due to its large diameter there were some clearance issues with some heat shields and exhaust brackets just in front of the diff. It came with spacers to lower the diff some 10mm or so, and the heat shields required some simple bending. Your only other concerns should be with how your exhausts have been fitted, ie if they're quite close to the factory 2-piece shaft, it might need to be changed a bit to give some clearance for the larger diameter CF unit.

If you have a ute, these shafts won't fit, otherwise all systems go.

Would you have any photos of the mods. Might help a bit

[BigJim]

Put me down to as interested in one of these. Good chance i will need one with the new combo.

GTO and sedan shaft are the same length. I gave a GTS Coupe one to a mate who fitted it straight up to his sedan, and i also had my GTO shaft next to another mates sedan one and they are exactly the same, we couldnt tell which one was which when a month down the track i went to grab mine to fit it back up.

[taztassio]

ZOMG WHAT!

any to suit l67?

would need to know the difference between in length i suppose!

voodoo, you able to ask them for me!

[taztassio]

also, how u measure your tail shaft length? i measure from rubber donut to rubber donut, and its 54" long.

also, what is the weight difference with the cf? EDIT: their website says 14lbs. will be awesome and should net a tength or a few over the qtr due to less rotational mass!

how do you go about mounting it to the differential end of the car?

and whats the info on the rear axels and stubs?

cheers

Nick

[seedyrom]

I guess I just had concerns on the whole 1 pice side of things

Though the power of "sleeping on it" made me realise that the donut that the tailshaft runs through at the moment will become null and void with a one piece

http://www.oz8.org/gallery/albums/Seedyrom/DSCN4542.jpg

The dip down that happens after the donut attached to the underside avoids the metal heat shield.
http://www.oz8.org/gallery/albums/Seedyrom/DSCN4547.jpg

Like Justin said, I reckon tinsnips and pliers will be employed to make it fit

So I took some rough as guts measurements

http://www.oz8.org/gallery/albums/Seedyrom/DSCN4543.jpg

And I've come up with this.

Feel free to accuse me of shit measurement taking

A-A = 1379mm

B-B = 1360 mm

http://www.oz8.org/gallery/albums/Seedyrom/yoyohomieg.jpg

[GTS Listy]

What does the stock one weigh. 6kg or is dam light. Guess the stock one would be around the 12 to 15kg i spose. Add that weight reduction in a 7000rpm car that will be pretty good.

By the looks the GTO and the Sedan are the same. I will go with you Jim on this one. Good enough for me.

Count me in then.

[VooDoo]

Chris AKA Mr Geforce1320 is a member here and will come and advise personally. The last group buy i arranged went pretty well (axles) and he may offer some of those again too.

Seedy: yours is a VT so you dont have the donuts like the pontiac GTO's. Best if Chris answers your questions direct.

[VooDoo]

Pricing from Chris for everything

If you get at least 5 sets of the carbon fiber driveshafts together I can go $1150. ea and that is the shaft and billet yoke.
I wish I could go lower on the price but there is a $100. price increase that went into effect this month and there just isnt much of a mark up in the cf shafts.
If anyone wanted one of our 3.5" aluminum driveshafts and billet pinion yokes I could do $750. ea on them.

On the bolt together 300m stubs, with a group buy of at least 5 sets, I can do $699. a pair. That is $50. off normal price.
The one piece 300m stubs, on 5 sets, I can do $849. a pair and that is also $50. off a pair.
The 33 spline stubs are the same price.
The outer stubs are normaly $699. a pair but if you got a few sets together I could go $649. a pair.

[seedyrom]

Hmmm ... I don't want to be left out of the party with my crappy protrusion from my box.

http://www.oz8.org/gallery/albums/Seedyrom/DSCN4558.jpg

I might just wait till I put the manual box in to put the drive shaft in.

http://www.oz8.org/gallery/albums/Seedyrom/DSCN4382.jpg

It has the "donut" that all the cool kids are talking about

[choppo]

Hey Seedy,

how come you chose to keep beer bottles as pets

I love random images from people garages :lol:

Stu, put me down on the interested list please

Anyone interested in the stub axles?

[taztassio]

voodoo, i would be interested if i can get for v6.

i measured 54" from the tailshaft rubber donut to the same, at the face facing the centre of the shaft on each donut.

so basically like this:

[seedyrom]

Thats a huge bitch!!!


Yeah, noticed on mine today, its a pity the driveshaft isn't down the middle of the tunnel, but to one side (the drivers side)

[GFORCE1320]

Hi guys :wave:

Looks like this thread has really taken off.

Here is what I'll do. Instead of trying to get a bunch of guys to jump in on this group buy, I'll just have a sale for the month of July.
The sales on my products are allways a big hit so I'm not worried about how many people we can get on board. (pricing below)

The way our tailshaft (we call them driveshafts) and billet pinion yoke package works is you replace the 3 bolt stock pinion flange with our billet pinion yoke.
Our billet pinion yoke uses the large 1350 series u-joints.
By going this route, we eliminated the aluminum adapters like the some aftermarket companies use and even the BMR set up above uses an adapter called a companion flange to adapte the tail shaft to the pinion flange.
By eliminating all the adapter we have also eliminated all the areas that have caused vibration problems with other shafts.
There is a bit of modifications you need to do in order to get the large 92.25mm shaft to fit.
The rear seat belt bolts that come through the floor on the GTO have to be ground down and shortened and sometimes you have to bend an exhaust hanger out of the way a bit.

If you have any questions, please let me know and I'll get on here and answer them.

I'll tell you a bit about our other products.
We have an innovative new bolt together inner axle stub that allows you to seperate the stub from the cv wheel if you ever damage one but the real reason we designed them to be bolt together was to get the manufacturing cost down and to allow you to up-grade to our 33 spline axle stubs.
If you ever decide that your making the kind of power that requires a larger axle stub, you just unbolt the axle stub from the cv wheel and bolt on the larger 33 spline stubs.
The axle stubs are made of 300m and we have never had one fail. A very strong design.

http://i25.photobucket.com/albums/c91/nicholscl/GTO%20Axle%20packages/Level-2-Half-shafts-and-bol.gif

The finished product comes in our nice looking black e-coat. A baked on finish similar to powder coat but very thin layer.

http://i25.photobucket.com/albums/c91/nicholscl/GTO%20Axle%20packages/DSC02696.jpg

And we also have our one piece 300m inner axle stubs.

http://i25.photobucket.com/albums/c91/nicholscl/GTO%20Axle%20stubs/DSC02167.jpg

Then we have our half shafts.
Level 1 4340 half shaft package that is rated to 600 rwhp. These axles are in alot of mid 10 second cars in the US and AU.
A very popular axle package.

Level 2 300m half shaft package is rated to 1000 rwhp and is recommended for manual transmission cars and big power cars.
This has become our most popular axle package and I am proud to say that nobody has ever broken one of our Level 2 300m axles.
We have been as fast as 9.41 @ 154 mph on these shafts.

Level 3 300m half shaft package is just like the Level 2 but comes with custom built cv joints with 300m cages.
These bad boys are what Girch at www.LSXTuning.com runs in his car. He has been 9.11 at over 155 mph on them.

http://i25.photobucket.com/albums/c91/nicholscl/GTO%20Axle%20packages/Level2withLogo-2.jpg

Something we just came out with a few weeks ago and has been very popular with our Australian customers is our billet outer wheel stubs.
The factory stubs tend to break once you start getting into the low 10's or faster.
We have them in 2 versions, one to be used with the factory press in wheel studs or we have them drilled to use the large 5/8 drive studs.
A big plus with our outer stubs is we shaved over 1.5 lbs (.68 kilograms) out of each side with our new design.

So does that mean we individually order through your web site or do we still go through the forum.
Also what is the freight estimate for the carbon fibre tailshaft/yoke package. Should not make that much difference where but for example post code 0812.

Is that all we need to do a changeover or is there bolts or other bits required. If there is please advise as up what, as you can get stuck with parts very easy up my way.

Any idea of weight savings over the stock unit
Thanks and it looks like a great product.

The driveshaft (tail shaft) packages come with everything you will need.

Shipping on the tail shaft package is $105. for 6-10 day shipping.
About the same for stubs and $215. for half shafts
Half shafts and stubs is $275.
I ship everything with the US Postal service.

Being a ute mines a longer shaft.

Are the carbon fibre tailshafts in stock or is their a wait. I will be able to purchase in about 2 to 3 weeks but put me down for one.

Thanks

[taztassio]

im very interested in a cf tail shaft for my v6, more for the weight saving rather than me braking it , ahaha.

I measure the tail shaft from the inner face of each rubber donut and i got 54" length. does that sound right? what are the stock v8 ones?

cheers

Nick

btw, 2-3 weeks sounds good, waiting for group certs so i can do tax ;)

I'm not sure if an autos a different length, i'll check mine tomorrow.

Not sure what the stock measure but our's are 52.75" from the center line of the ujoints. If you got 54 then that sounds pretty close by measuring the donuts.
Here is a measuring diagrahm if someone wants to measure up for one just to be sure. The "W" dimension is what I need and I can figure everything else out.

[GTS Listy]

Excellent. i will put my order through in about 2 weeks. I am very happy to find a tailshaft as it has been about 2 years in the search. Less that this if I was happy with compromise as there is some good gear out there but vibration and extra noise was the issues. Resolved now and they look great. Add to my bling. :lmao:

Voodoo thanks heaps for this too.

[taztassio]

I jsut measured mine from outer donut face to outer donut face (i think to correspond to the 'W' measurement) and i got 57" and 5/16ths.

[seedyrom]

so confused about the lengths everyone is getting.
My initial measurement of 1379mm is 54.2 inches.

So i'm saying 54 for me :mob:

[GFORCE1320]

The "w" dimension is taken from the back of the transmission to the front case of the differential housing.

The red lines are what I need the measurement taken from. (Please exuse my crude paint skills, LOL)

The standard GTO shaft is 52.75" from the center to center so I'm pretty sure if your getting around 54 then they are the same.
If I get a "W" dimension then I can computer the length needed by subtracting the lentgh of the billet pinion yoke.

You have the entire month of July :)

[choppo]

Actually while ive got you on line, can you do a calc for me to see if the max tailshaft rpm will be an issue? As you will see im running some strange gearing i think.
The average track here (circuit racing) i get to 155mphr down the straight. No prob... BUT;
ONCE a year, i will run at a track (called Bathurst) with a HUUUUGGGGE straight - you can really wind it out. Im estimating 180mph if im brave enough.
Now as im using a standard T56 box, ill be in overdrive 6th gear and probably using a 3.46 diff. Actually lets go crazy, say im using a 4.7 diff for the purposes of this (to give a safety margin).

With that set up the tailshaft will be spinning at a billion rpm (i.e. vs running 1:1 final gearbox 4th only and a real tall diff 2.xx). I have 18" rim with 265mm 35 18 tyre.

Bit of a calculation i know.... ill see if i get time today to work it out myself. Just want to check this tailshaft rpm isn't an issue

For all the knockers, yeah i know i have up the diff to min 3.46, but would like to see anyway.

Well, I have to run an errand right now so maybe I'll work on that calulation later but the carbon fiber shafts in the length you will get have a 14,000 rpm critical speed and have been dyno tested to 180 mph with no issues.
I have customers that have had them to 160 mph and I have one customer that has ran a 9.03 @ 155mph in the 1/4 so I dont think you have any problems.

Yes they are. I have plenty of those in stock.

The only thing I'm currently our of right now is the Level 2 and 3 axles shafts.
It's going to be a couple weeks before I can have those ready.

Thanks

Excellent. My order will be about a week away. I will wait until my next race meet then get it ordered. Still will be July though. Great looking product.

Seems to be missing the diff so maybe contact Harrop about the GTO trutrack and be USA supplier for them and fill the gap. Not plugging them but just a idea.

I have the Eaton Truetrac, they are $550. US. It is the US version. I have tested them, ran 9.70's all day long on one.

[GTS Listy]

I need to back off on getting this for a month or two. Need to make sure things are good with the new combo first and get some testing done before spending in other areas. (incase I need more spending in engine area) A couple of months max but will let you know when.

[taztassio]

fuck they are so nice.

Will be purchasing when tax comes in. hope you will offer sale prices to track chat members when we finally to purchase :)

Sorry if this is a dumb question but is the rubber donuts on the stock VX sedan driveshaft replaced with this upgrade. Mine are on their way out so might bring this purchase forward to save replacing the donuts

Can someone advise pronto please because if not I will get the donuts replaced while the gearbox is out today and tommorrow.
If they are replaced with this upgrade then tailshaft coming next month.

It is normal price for 2 donuts for $480 parts only

[VooDoo]

Yes they are Listy.

I have a spare if you need one for a bit

That is great they replace them. I will get the CF tailshaft and billet end bits early next month. I will be in touch Mr Gforce.

[GTS Listy]

Chris
If you visit here please chaeck your emils. Been trying to get hold of you for a few days. Aussie dollar crashing. Please check the order and emails and can you get back to me pronto. I am trying to get the CF tailshaft sorted before the next meet and time may run out to get it here

Cheers

Cheers. I will give a little bit. Not sure how long the freight will take but by the sounds it may not be possible. All it was is that there is a change of back to back testing with the only mod being the tailshaft changing. Never know it might help specially so much of the time in the high rpm area

All sorted now and thanks Chris. About a week sounds good.

[GTS Listy]

Chris

Thanks for sorting this. Dam good price for this thing.

Happy camper and install is on Tuesday next week. I will get the diff readjusted at the same time to try and get that slack out of it.

The picks are in my GTS thread

[GTS Listy]

Well it is all fitted up. About 2 inches too short though for a sedan. I thought people had these in sedans already so am I the first or somthing. Strange as this has not come up. .
What is involved to install
Cut up some of the exhaust heat shieds, cut off one exhaust hanger on the back, modify tailshaft loop (most likely for those with them). Exhaust room seems ok but it would be close with 3 inch exhaust.

One good thing is that heaps of the driveline slack has gone and it is all very firm to drive. Feels great actually and a huge relief that the 4.11 diff gears are ok. Obvously I have not given it heaps bar a quick squirt for a bit of fun. I will need to sort out a modification to suit the sedans. Not impossible I am sure. I will have a think and talk to a engineering place.

See photos
All good here

Not so good here. It still has about 2 inches holding

[taztassio]

a longer removable yoke should work and be cheap

[GTS Listy]

a longer removable yoke should work and be cheap


Good idea. I will email Gforce as I guess it would be in there interest to have a sedal version. Should not been too much tooling. Then they open up a the sedan market.

Also I managed to get the car to about 250 today and there was zero vibration. Totally smooth as silk. It took several dyno runs without any issues at the gearbox connection
Also ridding the donuts it sure does tighen up the driveline. Takes a little to get used for everday stuff but just about got it right now.
Over all I am happy but needs a litte mod. Easy ???

Still I can not believe I am the first person with a sedan to put one of these in. I thought heaps of people got them but no so.
They are a dam find looking bit of kit though

[ova400]

did you manage to weigh the standard tailshaft and this one??

Yeah i thought many had installed them! i will be looking for one when i do a t56 conversion. When i get the cash...

[CHAMRA1]

Chris .

Do you make drive shafts for a VE yet ?
Pontiac/G8 etc .

I need some sent to Melbourne ?

[GTS Listy]

did you manage to weigh the standard tailshaft and this one??

It was about 3kg difference. The billet ends are pretty heavy compared to the rubber donuts on the stock shaft. The actual CF shaft is only 2-3kg in total but the unis about 4kg. The difference is the distribution of the weight. Instead of in the middle and now no center part the weight it is now on the ends and apparently this is the way to go.

I have done some dyno runs up to 250+ and also some full power runs and it all seems fine like no vibration and the section in the gearbox is fine. I am in talks to come up with a sedan solution on the uni being short. I will talk to Chris about this too as I now have the exact measurement to make a sedan version but considering I seem to be the first with one of these on a sedan it would be hard to say it is going to be viable for him.
