ST45's have worked very well at both Daytona and Sebring, excellent performance and minimal wear. My other brake pad experience on this car is only with the stock organic pads, which work well but wear down quickly. Note that the ST45's - when new at Sebring left a heavy residue on the CF wheels. After immediately washing the wheels, there was still rust type residue which looked to have pitted the wheel finish. I used Iron X spray, which reacted with the metallic residue and completely cleaned up the front wheels to my great relief.
