I have a few questions about the E46 M3 rotors.
1. Why does the European E46 M3 have cross-drilled rotors and the US
M3 have plain rotors?
2. Will cross-drilled rotors provide improved braking?
3. Will the European cross-drilled rotors fit on the US M3?
4. Will I need to replace any additional parts or hardware other than
pads if I get the cross-drilled rotors?
Thank you,
G.S.
