Brake Cooling

[handbrake]

Anyone currently using or considering any brake cooling packages?

air/water/both?

Anyone with experience on brake cooling and what works for the amateur?

Pics of the Willall sytem also. Much more info yet Martin other than what is on NAGTROC?

Anyone know what the AP/Stillen active brake cooling kit is? Slip you got yours yet?

here are some pics of the PWJDM front lip with ducts. nice.

have referenced some images from GTRBlog and PWJDM, thanks Kris.

And some pics of Martins Willall water cooling system. hope you dont mind martin? pinched from your posts on NAGTROC

Just noticed this thread

We are probably the hardest on GTR brakes of anyone in Australia. It comes from living in a state where Mallala is your only real track, and its a brake destroyer. The whole reason we went down the path of our WR35WS system is we got sick of spending $1000 on brake pads every three track days or so, and another set of AP rotors every 6 months. Workshopping some ideas from an ex Group A engineer came up with WR35WS. It works well enough to contain from pad and rotor wear by around 30% or so (its hard to gauge), but definitely knocks 100C or so out of the brakes, which keeps them out of rapid destruction mode

More info here - http://www.willallracing.com.au/performance.htm#wr35ws

To give you an idea, at a full pace lap of Mallala on a solid Carrera Cup time we will use just over a litre of water per lap. Coming into the pits, the crew can touch the rim afterwards without gloves. Before we used water cooling we had numerous problems with burned crew and one instance where the pads were completely on fire, which is never pleasant, and thats after a full cool down lap

how does that carbon lip with integrated cooling work? is that it, just delivers air about a foot from the rotor? surely that doesnt work?

Yes I doubt it is effective

some of the Tarmac guys up here have fabricated some better flexible ducting for the R35 I think

I concurr, that PWJDM unertray/ducting thingamajig is of no brake cooling benefit, it's yet another shiny thing to capitalise on 35 some owners.

We made some simple alloy sheet air guides up, just in an effort to guide air toward the centre of the rotor/hub area. 35's are fairly crowded (as are most other 4WD cars) around that area, and aren't as easy to fabricate a really effective ducting arrangment due to those pesky driveshafts while allowing for wheel and tyre clearance on lock.

would it be more effective if someone came up with a wheel design mimicking E35 M5's? A case of back, to the future?
