Question on race pads
For last weekend's event, I had:
- new OEM Z4 3.5is front rotors, new rear OEM rotors
- new Cool Carbon S/T pads all 4
- newly flushed to Superblue
Problem was when the brakes got really hot, a lot of steering wheel vibration came in. After 1 min cooling, everything became normal, so I went out for more. Another 3-4 laps in, problem repeated. Well, after asking around I found a solution: PFC01 pads. Now the question is:
Do I need all 4, or should I just get the front 2?
Premises:
CC pads for daily; PFC only for track; everything else is stock
Thanks in advance for your advises!
