German Super Touring racing in the nineties gave us some of the most aggressive four door cars ever. This Underground build puts that look on an E36 sedan with the Flossmann STW Street Race kit and a chassis to match.

The build plan
The Flossmann STW Street Race kit brings touring car bumpers in 1996, 1997 or 1999 style, wide front fenders, a new hood, front and rear doors and the classic STW rear wing. It is pure nineties touring car attitude.
Underneath, CNC71 PRO camber plates, a front strut brace and a 6-point rear X-brace make the old chassis sharp and consistent. EBC Turbo Groove rotors handle braking.
Inside, the CNC71 short shifter and bucket seat bracket make it feel like a race car from the driver seat. Four doors, zero excuses.
