only e46s year 2001 and above can use SB..since the accelerator uses drive by wire system instead of cable..
Sorry for late reply Bro, too bz. Yes, adjustable. Just press the button for 3 options : Hard (Sport) or Soft (Medium) or Off.
Got from Bro Ken46 for RM460 (incl postage), still looks new, w box & instruction. Since I can't use it, just want to let go same price, RM460. Item is in KK, Sabah. I'm in KL tis week & next week, so can hand carry oso ;-)
