The ideal ratio depends on the application. 3.73s are ideal for autox and good for road racing. The bigger ratios are for drag racing.4VMENACE said:And why 3.7.3's? If you chose them out of the blue, get 4.30's instead...That an't a Mach1, its a Cobra, to gear it effectively, your gonna need 4.30's or more

Nope... for autox, anything over 3.73 / 3.9 will slow you down because you'll bump the rev limiter in 2nd, or you'll have to shift to 3rd, and either way you'll lose time.Black99CobraMofo said:i'm getting 4.30's should be a good compromise between 3.73 auto-x gears and 4.56 drag gears...
