Well the car is mostly for track use, it has GTM supercharger with over 515whp and 390wtrq, fortune auto 500 suspension coil overs with 16k/12k springs and running re71r at the moment. Z1 2 piece rotors with Carbotech 10/8 XP pads. Also running brake cooling ducts. My issue is that I get brake pulsation after ~2 days of use from front rotors. I assume is just pad deposits from excessive heat. It only happens at low brake application. Full braking is smooth. Rebedding does not help. Was going to go up to XP20/XP12 next on stock calipers but wanted to know if brembo caliper upgrade would be worth before spending tons of money on full bbk setup.
