We 3D laser scanned several cars and 6 cylinder motors (not for use with 318 with 4 cyl.) and then CAD designed this strut tower bar for maximum clearance and strength to cure classic issues with BMW's destroying themselves after coilovers are installed. Laser cut plates and laser notched tubes are both CNC bent for accuracy before going into our automated robot welding for the stitch pulse MIG process which has very consistent heat penetration and low spatter. Finally we powdercoat the bar with the signature copper metallic while the round weld on plate, (required for spacing the bar base plates off the humps on top of the strut towers), is coated in steel-it (a weldable coating) so that it wont rust if you temporarily bolt it right on with the strut tower bar, and its ready to weld along with the strut tower to apron/fender plate when you are. **Does NOT clear E36 with S54 engine swap.
