955 Cayenne Turbo S brake rotor upgrade
I have a MY05 955 Cayenne Turbo S with large disk brake upgrade (380mm x 38 mm 2-piece fronts and 356mm 1 piece rears). Can anyone suggest a replacement disk rotor that can be taken to track, for a little fun?

I don't believe anyone makes an alternate properly sized rotor for the fronts. Proper size is 380x38. You can find 380mm diameters, but not the proper thickness.

I've always wondered. Why isn't it possible to swap to a different thickness of brake rotor? By design the brake system has to expect a range of thicknesses for brake rotors and pads...
380x36 is a much more common size and is available for VW's and Audi's.
The Cayenne is a heavy high performance vehicle but it's hardly the only one.

- If you start 2mm narrower, when you get close to the end of the pad life, the caliper pistons may be forced too far out, which could either pop the seals off, allow them to **** in the caliper bores, or create a leak.
- Also, starting with a thinner rotor reduces the available heat sink which may cause the rotors to warp prematurely under heavy use conditions.

Pads are cheap and easy to replace. You're talking about a mm on each side. What that effectively means is the moment your warning goes off - replace them immediately. A lot of people replace pads before that just to save on the cost of the $20 sensor.
As for warping - it's possible I guess but unlikely unless you're really pushing the car. There are other similar weight and HP vehicles with the 36mm rotors. Plus so what if they warp? The price difference means you could replace them many times for the cost of the 380x38 rotors.
$50-250 versus $1000+ per rotor is a pretty big difference.
My rotors are still good but I might try it when it's time.

For my E55 front rotors I use and after market rotor that's a couple MM thinner and a few $ big ones cheaper. It's been 3 years and no problems. Of course its my DD and I'm not racing from stoplight to stoplight. If I were I'd stick with OEM.
