First of all is it an E36? Are you sure the car has a Supersprint exhaust, not a Tri-flo? Is the blower a Vortech unit? If these are true and the roll cage is black, then I have a pretty good idea whose it is. An 18 year old Chinese kid with rich parents by the name of Mike. He crashed the car twice; once last winter on a curb and then on the first BMW driving school in April he really wrecked in the rain. Parents got fed up and bought him a Civic instead. The shop that did the cage (same as mine) is O'Brien motorsports in Brampton and the performance mods were courtesy of Motronix Motorsports (905) 856-3811.
