Hi guys, I've recently purchased a 135i, and from where I'm looking, it has pretty meaty calipers(Brembo?) and rotors. But everything I hear is that they should be replaced with BBK when doing anything (might be an exaggeration) at the track. From where I stand, I feel like braided brake lines, racing pads and rotors would go a really long way and save me thousands on a BBK kit, which should only really be a requirement when the car is really getting pushed/long distance lapping. But then again I haven't tested this theory myself.
What am I missing here? Thanks
