Stoptech's Street Pads are still our favorite pads for daily and semi-aggressive use. They remain quiet and predictable through their lifespan. Only downside to these pads is they are a little on the dusty side, but not terrible. Stoptech's Sport Pads are recommended for people who autocross or for light track events. If you daily drive your GT-R and don't partake in these type of events, it's recommended to stick with the Street pads.
