advevo,
Bugger, knew someone would ask me that! The answer is I am not sure - all I can remember is that they are the most extreme carbon metallic pads - will find out though and let you know.
Am putting Pagid on the rear - haven't tried anything else on the front.
The braking is truly frightening - particularly with slicks - and absolutely zero fade. I was braking from 120 to 30 and doing it way past the brake marker on the track, and did that for 20 laps without stopping - no problem at all - apart from destroying the front drilled discs through overheating!
The ducts and groove discs fixed that. The only way to make the car stop quicker would be to drive into a wall
