Through the years we've tried almost every brake package for the OEM brake setup on an S2000. This is what we've found to work best on a track S2000. Works great with high grip street tires up to a Hoosier A7. This is what we use on our GLTC race car.
This kit includes-
Ferodo DS1.11's (Both front and rear)
Centric Rotors (Both Front and Rear)
Motul 600 High temp Brake fluid, 2bottles
