Ok so I had some time today to experiment a little so I decided to try and convert my LM chassis to fit an Acura NSX MM body.
It took about an hour to do and the only modification I had to make was to remove about 2mm of plastic from the front edge of the shock restrictor plate hole. Suspension travel is minimal but the wheelbase now fits!
I also swapped the wheels and reassembled the LM/MM T plate in the MM position. We’ll see how it runs next time we do a test session.
