***Editors Note: This is such a wonderful build. Proof that you dont need a S52 or S54 to be out there loving the E30. Strong M20 and a very sanitary build. Its got a long list of upgrades and many will get overlooked. Definitely not the fuhraze type car, but one that uses great OEM components and proper upgrades to build a fun track car. Congrats DigitalWave, you're the May 2018 Car of the Month

Story behind the car:
This car was purchased in May 2016 from the original owner. It was the perfect blank slate for a track/autocross/weekend warrior. Having owned E30s on and off for over half my life, this has been a fun build to rekindle my appreciation for this platform and take a build in a direction I had never tackled before.
UPCOMING AGENDA
Aero package (side skirts, full undertray splitter, spare tire well delete, full rear diffuser, rear wing)
New wheels (3-piece wheel rebuild project?)
RHD Engineering ITBs
More weight reduction (lexan windows, more CF body panels)
