Hello, I have just become the owner of a Porsche 991.2 Carrera Base. I want to install 10-piston calipers and 410mm front brake discs, 400mm rear. what wheels will be good for such a car? I want to buy 21" so that they are flush with the fenders without spacers. what are the dimensions and width of the front and rear rims?
regards
Marcin

Don’t get me wrong, I’m all for big brakes, but are you sure with 10 pots? They are more about pulling up a big bus than performance. They would weigh a ton?

When they are that big they wear the pads unevenly on the ends. To counter this, some large setup, cut the brake pads in half (not really). They put 4 pads per wheel instead of two long ones.

Here’s my little 380 / 380 setup.

The only way you’re getting that size rotor is to use a PCCBs or Surface Transforms rotors. An iron rotor of that size will weigh 50lbs and no one offers them. The largest iron rotor is 380, you just don't need any more mass than that to have reliable track brakes. If you’re going for looks and just want to fill the opening behind a 21-inch wheel, then its carbon ceramics.

As far as wheels any vendor that offers custom offsets will make the wheels fit perfectly at any size without spacers. BBS, HRE, Forgeline, etc. There are a bunch of wheel vendors on this forum and most of them will get you a perfect fit.
