My DIY Brake Ducting (WIP)

[Aeron]

Well dad and I spent half of today installing/making our DIY brake ducting. I removed the front fog lights to use that area as air intakes. Because of the size of the hole in the bumper, and the size of brake ducting pipe I bought, we need a 4? 90? angled PVC elbow. Problem!!!! You don?t have 4? between the bumper bar and the chassis rail behind the hole. Solution!!!! Put the PVC elbow in boiling hot water on the stove and quickly pull it out and shape the pipe by hand. Yes, it was hot. Once you?ve checked the clearance and moulded it into the shape you need it should look like this?

4? PVC elbow

Then you need to fit it to the car. I took a cue from V8Supercars here. Instead of attaching the pipe to the bumper bar, why not attach it to the car and have it so that when the bumper is on, the holes line up. This way the front bar can be removed and put back on in no time at all if you need to work on the car.

So anyway it took most of the arvo to get it all to line up and sit against the back of the front bar. Oh, and we?ve only attached the elbow on one side of the car. The silicon ducting isn?t attached to anything yet and that blue tape is just there to see how the ducting will fit behind the front bar when its attached.

To stop rocks and debris from entering the duct I moulded some wire mesh (also used in the mouth of the front bar) to fit over the hole in the front bar. It is attached to the front bar and sits between the front bar and the PVC elbow.

Im quite happy with it :D

I haven't done that bit yet Troy. I'll do a bit of research on the best placement for the opening first. :yep:

When its done I'll be sure to post up some pics of it.

Another good DIY thread... :bravo:

Top stuff mate ... that looks great.

:bravo:

I think Scotty had a heap of pics somewhere that showed the best way to position it with the rotors ... I think it needs to blow straight at the centre of the rotor from memory, that way the cool air is forced through the rotor veins.

As a side note for anyone that doesn't know (I'm sure you do Aeron) ... the rotor veins must curve towards the rear of the car, it doesn't matter which way the grooves curve (if your rotors are grooved), but the veins MUST curve towards the rear.

Well done Aeron, keep the pics coming.

Good Work mate!

that was on my christmas/new years to do list.

As nick said you really want to get the duct to the inside of the rotor... BMW have an aftermarket spigot for this... which I was going to get made up. I bolts to the insode of the hub (I think)..

Good work mate, now desgin mine for my r33 :D

Yep, you'll need to place it for the center of rotor otherwise with all the heat changes, will crack rotors

[Aeron]

Thanks for the info boys!! I'll have to put my thinking cap on for a way of mounting the pipe so close to the rotor.

Thanks!!

[Aeron]

I finally got off my bum today and finished off the ducting. The hard part is getting the duct colse to the middle of the rotor without it fouling on anything, so its about as close as I could get it.

Hmmmmmm... just a few different angles mate, perhaps with the wheels off.

Again, good work mate :yep:
