It also allows the correct belt allignment to use the spec r gear diff.
Can you use roll bars in rear with that mod? Looks like it will interfere with the gear diff, itīs a close call already with a standard mounted gear diff.
Raced this weekend with a box stock car with a option gear diff. The car was ok but my driving was not, finished 6th. Due to the flex I think the car needs some different setups but itīs fast.
