I use these pads on a 1991 Prelude with upgraded calipers and rotors. The car is autocrossed regularly and these pads do an excellent job of stopping my turbocharged car once the brakes are warmed up. After an intense ride, the amount of brake dust is very noticeable, but it's worth it. The pads have been around for a little over a year and the only thing that bothers me is the occasional squeak, but even that is worth it.
