BMW E82 tracktool


Overview

One of our latest projects is #e82v8tracktool.
The real tool for the track is fast, fun, reliable and safe. We have made a competitive car that delights every passing circle, it’s nice and not scary to roll over track.

For the basis we took the street, slightly modified BMW 135 coupe, rolled under the hood naturally aspirated V8 with Dual Clutch Transmission, welded the frame and plastic body panels.

The most frequent question that you hear next to this machine is “Is that a 1M?”. We say “No, this car is much way better!”
