Race Brakes RB2
1. Bite hard, havent had them fade yet.
2. Wheels are still clean after 300km driving.
3. Squeal when hot.
Oh and these are in S5 RX7 4-pot calipers.
The problem your experiencing could also be due to the heavier braking force on the front causing the car to drop at the front, thus effectively lifting the rear of the car making it lighter and needing less braking force applied in order to lockup.
