Guys, do you know if there is a difference is diameter and calipers between the steel brakes and the ceramic brakes on a 2016 GT3 RS? Do the steel vs ceramics change the offsets? I personally don't think so, but curious if there is an expert that can confirm this.

The reason for my asking is because I am concerned when going from steel to ceramics is the rotors larger and is the brake calipers different in design that could affect the fitment of aftermarket wheels.

Thanks!

PCCBs are larger, discs are 410mm front, 390mm rear v. 380F/R for iron. Caliper is larger up front as well, not sure about rear.

I love physics because there is no way the results are unknown.

Larger diameter will always improve breaking as long as all other issues remain constant. If same material is used then weight will go up.

I will leave it there and let everyone else to think this one through as mass times distance comes into play.

That is the info I'm looking for. Thank you!
