The original specs I have also showed stock brakes but I'm sure the rotors were upgraded. Of course the car was a lot lighter which means better braking with the same brake system. I would also bet they used a Pagid pad and probably a steel/Aluminum rather than a Cast Iron/Aluminum rotor. Brembo sold kits with our same front Caliper with up to 380mm rotors so a bigger rotor does fit and may have been fitted.
