I think a high 60 might be possible with the current setup, but its a matter of having no traffic. Towards the end of the last session the Evo was holding me up on a few point on the track, I just couldn't quite get past him safely. The PBR-M are 355mm, 6pot front and 355mm, 4pot rear with EBC Blues all round. Back in 2009 I did a few races with the factory 2pot brakes and trying to stop from 190kph was just ridiculous. I literately had my ass off the seat standing on the brake trying to stop. The PBR-M work wonders, Although I did managed to crack a set of rotors just from excessive heat.
