I live in Florida, so heat is an issue. Sebring is my home track, so speeds are high, the track is heavy on brakes. I drive in the red/instructor group, so I use the brakes pretty hard.
I'm one of those who finally installed a BBK (ST60), and kicked myself for not doing it sooner. I installed front BBK only. Excellent track performance and modulation with carboteck and Endless track pads. The street pads are very good too. I now get 6-8 track days out of a set of pads. I wouls have saved a lot of money if I had installed my BBK sooner. Also, I feel that I am not using the system at 100% of its capability, so I feel safer.
Before that I went through all the time and money of: Motul brake fluid, track pads (Pagid Yellows, Carbotechs), cooked and replaced my OEM front calipers, added a Cantrell brake cooling kit. The cooling kit meant that the pads last 2 days instead of 1 day. And I felt I was running the OEM brakes at 110%.
