Lets Talk Brake Kits

[pharmd]

What pad are you referring to? Have a coefficient of friction / temperature chart handy? I always worry about the borderline street/track pads. I am a stickler for quiet brakes. Nothing worse than a well thought out car with squeaky brakes.

I have run Wilwood BP 10 pads in the past that have been really good over 700 degrees but never had them above 800. 1000 seems pretty extreme for a street pad. This was on a lighter weight 3rd gen with only 300rwhp / 400rwtq on a 13" x 1.1" rotor. I would have to imagine with a smaller rotor, more weight, and more horse power, the OP will not be able to use a street pad.

The additional mass and radius always buys better braking. Sure there are other downsides like higher un-sprung and rotational weight. Everything in a car is a compromise. Most of us on here are not all out racers, including myself. For me overkill on brakes is worth the weight. Hitting the margins just right is fine for racers. Of course racers wouldn't be running street pads either.

Regarding SAE, no I am not a member, I am an aircraft guy, cars are my hobby. A paragraph paraphrasing the technology would be fine.

Car will make around 500rwhp when all said and done, car has a few lightened pieces, but is still likely going to be heavy. Would the BP 20 pad be a good compromise (street/track) considering the power/weight of the car? That was the recommendation of Wilwood.

The BP-20 will probably work ok. It is advertised to over 900 degrees. They might be a bit soft the first stop or two in the morning. My BP-10's were soft until they got a tiny bit of heat into them. I'm sure the 20's will be worse. I also don't know about noise. The BP-10's are quiet and moderatley dusty.

I would run the biggest rotor possible. Something like a 14"x1.25" in order to keep temperature out of the pads. With this combo I'd say there is a pretty decent chance you can run street pads on the road course.

What caliper are you thinking about, the SLR6? I ran the 4 piston version, the FSL. I liked them alot. Another option would be to run one of their big calipers like the W6A which will keep heat out of the pads even better.

I would still take a look at the CTS-V brakes though. They really aren't that costly. And they work really well on the 4200lb, 556HP CTS-V.
