Supra gearbox or M21??

[the ski man]

to check out my ratio combos i use this nifty program:

allows you to input everything as its designed for clubman kit car builders.

i've run some numbers and the 2.7 with 4 speed looks great, the lingering question is how tough the combo will be in a higher power combination.

i had previously had 2.79 rear with the m21 but kept snapping teeth on first and second. i ended up getting rid of the tall diff and i hadnt had an issue since.

im also really grateful for your input Byron, and like the suggestion, it means keeping some sense of originality about the car but making it user friendly.
