M5R2 Manual Trans.

We highly recommend the 3.27:1 ratio for the '89-95 supercharged manual transmission cars. This is the ratio that Ford should have put in them from the factory instead of the 2.73:1 ratio.

The 3.55 ratio should be considered aggressive for the '89-95 supercharged manual transmission cars. If you do a lot of drag racing or rarely hit the highway with your car you may want to consider this ratio for this application.
