Unfortunately with the AP Racing caliper bracket to offset the caliper the gap is even tighter. You also have to deal with the fact that everything moves when you turn the wheel.

Not sure if I'll get this done by my next track day on Memorial day, but we'll see. It's a short track with 3 heavy braking zones and not a lot of time for cooling. Either way I'll have rotor temp paint and caliper temperature gauges installed. I'll be using 1800F MOT Sintered track pads.
