I have an 88gt with a 5-speed and a basically stock motor. I currently have 3.08 gears, but I want to switch. I "think" I want to go with 3.55's but I may consider 3.73's. The car is driven on the highway a fair amount but I intend to do some auto-x as well as some HPDE driving. What gear ratio would work best for an "average" auto-x course? For anyone who has swapped from 3.08 to 3.55, was it "enough" of an improvement, or did you wish you went taller. Thanks.
