Want to do a gear swap. With the 5-speed auto, its seems the car could easily handle the 4.30's in the 1/4 mile. The charts I have checked show rpms about 600rpm higher then stock with the 3.55's at freeway speed. Yet when I read posts / magazine articles / the gear of choice seems to be 4.10's. Anyone out there have 4.10's and wish they went more aggressive with 4.30's? Perhaps the opposite, anyone go with 4.30's and wish they went with 4.10's?
