I installed them on my 2004 Mazdaspeed Miata. The car is my daily driver and I see about one track day a month. These pads are a great balance between street and track use. I used new Centric rotors [ASIN: B000BZZPV8] and installed a stainless steel mesh. I flush the brakes with ATE TYP 200 DOT 4 [ASIN: B003VXRPL0] brake fluid about every six months so the car had a fresh flush. After that, the brakes were incredible. Never fades on the track and is solid on the road!
