Corner Weighting

[lautray]

I got talking to a bloke that has a bit to do with setting up cars for different forms of circuit racing & he mentioned corner weighting. From what I understood, corner weighting balances your car for optimum neutrality & handling. Can someone here shed more light on this? Also, anyone know who does this in Sydney & approximately at what cost?

Im not 100% what you are speaking of but I will say that when I was watching the V8's on TV the other day I saw in the pits that they have special scales that go under all 4 corners, so 4 different scales.

These allow the team to distribute the weight 100% perfect around the car.

Looked cool, Neil Crompton (I think) was doing a garage tour for the viewers.

Good luck mate and keep us informed.

You will need a set of coil overs. Without them its pretty difficult. Its a pretty simple matter of adjusting the ride height up or down, till you get roughly the same weight on each wheel. Can take quite a few hours to do it properly. East Coast Suspension at Kirrawee are able to do this for you.

Thanks for that. Coilovers are already on the hit-list. Will give them a call.

No worries Erik.... :cry:

Surely you just relocate your crap in the car to achieve this.....:up2sum: teddie to the front seat... child seat to the middle... wife to the rear passenger left etc...

no... oh...:headbang:

Don't know if I'm barking up the wrong tree but I've heard this terminology used to describe something slightly different. I was in Wholesale Suspension in Penrith the other day looking at a more track focused setup for the Cortina. Apart from being the only person not to laugh at me when I suggested this, the guys said they would weigh each corner of the car and fabricate the springs (harder or softer depending of weight of each corner). I'm pretty sure they refered to this as corner weighting. Anyway you should all be able to see if a Cortina can actually make its way around a track at the next Trackchat track day.

Talked to David at EastCoast Suspensions yesterday. Very knowledgeable bloke. He suggested a few coilover packages, which include supply & fit, alignment & corner weighting. Can tailor something for my needs. So will be going coilover before the Trackchat Wakefield event in September :D. EastCoast Suspensions (David) number is :9545-1044 (Sydney)

What waylow says is correct. It's pretty much impossiible to do it with any degree of accuracy without coil-overs. But - if you are fair-dinkum, it's the only way to go

You don't "need" coilovers but its easier to do
Its done with HQ racecars (double wishbones) to get them to go round corners better
Putting shim pads under springs to weight jack a particular corner

Its been done on my late racecar regularly to balance everything up
Moved battery, fire eztinguisher , etc to help balance

Thats the problem I have with my swift-IPRA rules state you can change the suspension, but must retain the original type. On the rear its a seperate coil and strut. So I can't use rear coil overs. The only way we can alter the weight is to either make up custom spring mounts (expensive and not worth the gain per dollar spent) or use extra rubber shims to lift or drop the chassis. Fronts are easy, as they have been converted to coil over.

If anyone is interested, I could do a write up on DYI coil overs (not the cheap shit ones you can get on ebay either!).

speak to noltec i have coil overs front and rear in my car and tein now do them to its just and adjustble base but then you have all the springs in the coilover range to choose from.i dont know how mine handles yet still off the road

[waylow]

Like I said, I know I can get the adjustable rear bases made (noltec don't make them off the shelf), but the cost isnt worth it. I will stick to shimming and adjusting the fronts. Its a kind of set and forget thing, I only run one spring rate for all three tracks.
