My freeze date is today. I switched back to steel rotors, went guards red, with black wheels.
After I picked up my 996 Cup Car I realized this is really a street car with an occasional open lap day; maybe 6-8 a year.

Where do you select the color of your wheels? On the Porsche Web site where you build the GT3, I don't see any option to change the wheel color.

For the US it's an option but you get gloss black. I'm going to get them painted satin black after delivery instead.

Are 410's really new, I believe a PCCB equipped Cayenne comes with 410s?

Yes, the 410's are new. The Cayenne PCCB's are 420mm front and 370mm rear and are for use only with wheels larger than 20".

Actually, it's 16.4% bigger. Circular area = Pi x radius^2.

410mm diameter = 205mm radius
380mm diameter = 190mm radius

That would be true if the entire surface of the rotor was swept by the pads. To be most accurate, you would need to figure out the area of the rotor, minus the area of the center, etc.

Bottom line, they are bigger. You ought to get something for close to 10 grand! Besides a lighter wallet.

Totally agree. Just all estimates, but trying to at least apply the correct math...

I think Porsche claims 14% more swept area for the fronts so the 15% estimate is pretty close.....
