Hi Mike, tipo is a bit of a joint effort with my mate trevor, who is racing it at the moment, down side is he's wearing it out, upside its gained a new lower FD and a set of £1200 AP brakes. These are biggest I can get on there with 15's 295mm circ. The coupe calipers that were on it were good, but the issue was with the warping of discs, the car has now got 4 pairs of brembo discs!! Hopefully the 2 part disc will reduce this issue, but its no gaurantee as I know they can still warp in this configuration. I dont actully know if they will be more powerful, a modest increase in diamter and great pad area should prove beneficial.
Don't even consider getting rid of yours, I'll cry if you do.
