Hey guys,
I was at my local shop today (Larry's Performance Werks) and we were talking about brakes (and about how mine are warped to hell). Then after talking to someone at iPd (slotted rotors on the way, wahoo!), Larry thought it would be really good to have a brake cooling system for 850s. Larry has been racing since I was born and now he instructs part time and runs a small shop here in Asheville. Anyway... He's going to fabricate a system like he has on his 911 Track car, and use my car as a ginny pig. iPd sounded really interested and told him they would sell like hotcakes, so he's thinking about marketing them. I'll be sure to keep you guys posted on the progress. If anyone is interested let me know.

Hey, that sounds cool.

keep us updated on how it goes.

One of our members is considering converting his (useless) foglights into apertures for brake cooling pipes.

I told him that it's unnecessary in view of his AP Racing 325mm discs which have enough radiating area - but what the hell, he's going ahead.

Regarding warped discs - check that your wheelnuts are torqued properly, this is a cause of much warping and is easily remedied.

And don't drive though mud puddles. As much fun as it is it will warp your brakes.

I plan to install some sort of home made brake ducts once I get my new spoiler installed. I don't know if it will help my 240, but I plan to auto-x the car a few times this season. Any suggestions on what to use for the hoses, and how large they should be? I was thinking of making my own ducts out of fiberglass, but I may just adapt some that are made for another car.

Simon,
I'm probably wrong here (it wouldn't be the first time) but don't you think that the bigger the brakes, the more heat they will produce? Yes there is more space for it to cool off, but it just doesn't make sence to me. Shouldn't More stopping power=more friction/heat? Though, I do see your point in that it has more time to cool as well.

towerymt,
I'll let you know what Larry wants to go with, but basicly tubing is tubing. My friend is building a custom intake for his 740. He is going through the same delima. I'll keep you posted...

I'm afraid you are wrong, Austin - if a brake disc has a large swept area and a bigger moment arm due to larger diameter, it will produce more stopping power with less application of the pads and thus generate less heat.

The larger radiating area will lose this heat faster, keeping the whole assembly cooler.

That's why racing brakes are as large as possible, to keep them effective under very high stress conditions.
