Wow, that is a pretty impressive looking front brake!
The new Stoptech brakes have about 50% more capacity than the already generous Brembo stock brakes.
We had to disassemble the rear upright when installing the rear suspension so the brake had come off at this time as well.
The Stoptech STR-40 caliper is huge and the bads have way more surface area than the Porsche Brembo caliper.
The rear Stoptech Aerorotor dwarfs the stock rear rotor. There is a lot more swept area and thermal mass to dissipate the heat. The factory drilled rotors will be prone to cracking under hard track use so the slotted Stoptech rotors will not have the issue.
As side profile view shows how much thicker the Stoptech Aerorotor is than stock and how much more venting it has.
