E30 M3 Race Car Project
BMW E30 M3 has been won so many races in FIA event back at the old day. It also included BTCC, ITCC and DTM race. It's been that many years, people still love E30 M3 so much and the passion will never end. One of my good friend has a 1989 model, and we've been racing in TCRA and SCCA event for many years. One day he decided to turn his E30 M3 from a half and half race car become a Pure Race Car just like the BTCC FIA car. It's took me more than half year from scratch to get done. The Roll Cage is copy those BTCC Gr.A Race Car. Multi points attached to the chassis. Front braces are extended to the strut tower; the rear braces are connected to the Differential and rear coil-over shocks as well.
