Quick question hoping for a quick answer because i cannot find anything about this through a good deal of searching
I have an STI clutch type R180 diff with a 4.44 gear ratio and i'd like to swap in my ratio from the original 1972 Datsun R180 3.364 (possible 3.545, but need to confirm) is this possible without any modification?
I am getting really annoyed with my 70mph 3300rpm cruising speed, and the terribly short gear ratio.
