The EBC Orangestuff 9000 Series Brake Pads have been designed to provide optimal performance for extended race use. These particular pads operate best when the highest temperatures are reached. These pads have been made with a pre-scorched surface which allows for a fast bedding process. These brake pads are also effective from the cold which does make them street usable if needed. These would be considered to be a more aggressive brake pad when compared to the EBC Yellowstuff brake pads.
If you're running big horsepower or if your home track is wide and has long straightaways where you need a solid pad to bring you down from those big speeds, then the EBC Orangestuffs won't let you down.
Please note that with the Orangestuff brake pads require a bedding-in process since this is more of a trackpad. Steady braking with stops from 60 to 30MPH for around 15 cycles would help for the first bedding followed by 4-6 heavier stops to really allow heat to build up in the pads. The pads MUST cool fully overnight. For track bedding, drive two laps at moderate speed while braking intermittently. Then drive two more laps with heavier braking while coasting to a stop then allow the pads to fully cool.
These particular pads will be for the rear calipers on your vehicle.
