E84 2014 X1 2.8 sDrive brake upgrade
Is the ECS brake upgrade kit that's a 6 pot BMW Performance basically from a 135i, truly an upgrade for my current OEM brakes? The rotor goes from 312 to 338 and you do get a sexy gold caliper but is it an upgrade? I sometime tow a 3500 lb boat and I would like the assurance that I'm over braked and not under braked. Any suggestions would be welcomed.
