M Coupe LTW

With the interior removed, it was time to remove the drivetrain. I needed to keep the chassis as a roller to get it to the cage builder. So the motor, tranny, and diff were removed. The diff was sent off to Diffs Online for a 4.10 35/60 ramp diff with REM polished gears and bearings. Sorry, no pics of the diff.

I then took the car to Robinson Racing in Cumming, Ga for the cage work. They built the cage in my IP car. They do good work. For this car, I decided to go with what I will call a 2/3 cage. Rear cage with a single diagonal door bar terminating into a forward plinth. This will allow for a forward half of the cage if I decide to add this later. Initially for tracking, I’m comfortable with this set up. Cage designs are very subjective and everyone seems to have an opinion. It’s all about tolerance for risk.
