My door tag translated to a 3.27 traction lock on a 1993 GT 5spd convertible - I have read that it was never offered with the 5spd - I have a set of 3.73 gears new in the box from Motorsport that came with the car but if I have 3.27's already I would like to try those for a while with a little shorter tire since it needs tires now and I am low on funds for a gear swap - what size tire should I try - currently it has factory 225/55/16's and I was thinking of 225/50/16's - ideas?
