Yes, for just st40's. Pleas keep in mind that this set has the st60 fronts which are 6 piston calipers and the rears are st40 4 piston calipers. There is a huge difference and price!!!! Rotors on the front are 380mm and rears are 355mm. That other sales was only for f/r 355mm rotors and 4 piston calipers.
Rotor hats are different color because of heat, these cars are quite heavy and produce a lot of heat when braking, hence why I opted for the st60's on the fronts. I have never had any brake fade with this setup. I usually track my car 6-7 times per year. The rotors rings were all replaced less than 1500 miles ago. I can usually get one to two seasons on rotors unless i run Millers full course in Salt lake several times which speeds will hit 155-160 on the almost mile straight and then they last about one season.
These rotors have only been tracked once since replaced and not at Miller motorsports track.
