Hello all. Just came back from a good/bad day at Hallet raceway. My 2012 cayman R has had a 4.2 liter Raby motor build. Just got a GMG roll bar-Recaro Halo Seat and 6 point harness installed. Fresh Motul 600 brake flush and Pagid yellows. First session on track went well-it was raining overnight and the track was wet in spots so I ran with PSM on kept the street/rain tires (PSS). On lap 10 the pedal went to the floor-boiled the fluid. Next session out I kept the PSM off as it was kicking in too often to maintain traction. Going much faster now but lost brakes on lap 5. Clearly this car makes a ton more power than stock-could reel in the GT3’s and GT4’s on the straights, so the brakes need to do a lot more work. I probably should have done a brake flush after the fluid boiled the first time. Looking at maximizing brake cooling for future events. I am thinking about Girodiscs, 997 turbo rear scoops and GT3 front scoops. Not sure that a bigger rotor/caliper is going to fix a heat dissipation issue (ie Essex system). Oh and I broke my right rear axel on hard acceleration. That is a story for another day.
