Some things...
Many around here go from the 215-40/245-35 setup to 225-40/255-35. That does nothing to either increase front grip or decrease rear grip. It is possible on the later model 135i cars to get 1.5 degree negative camber up front via alignment adjustment.
All sorts of mods get discussed around here, but I can't ever remember seeing before and after lap times. At least with engine mods there are dyno runs and time slips. Lacking good data, it is hard to believe just about anything.
The guys who say learn how to drive fast, are the smartest guys in the room.
