Looking to upgrade your M3 front brakes to CSL/Competition specification? Here is your very own CSL big brake kit from ECS Tuning. This kit transforms your 1-piece 328mm front rotors on your stock M3 to the much larger 345mm floating 2-piece rotors from the BMW M3 CSL edition.
These CSL rotors are cross-drilled by BMW to not only enhance looks, but to also increase cooling capabilities of the braking system. They are also directionally vented to further increase cooling capacities. This is a very simple bolt on procedure that can be done with simple tools & without bleeding your brake system. Once the wheel is removed, a total of removing & re-installing 10 bolts does the switch over. Go from stock to CSL in one hour!
This CSL kit also fits under factory 18" & 19" wheels and you can use any E46 M3 brake pad.
