if possible , one can always simulate a bigger rear end ratio by mounting smaller rear wheels.... and take it for a test drive .

The car will mainly be for street use, maybe a DE every one in a while.

Rear tires are 275's on my 10" OZ Racing rims for normal driving and then the 315/30/18's on the 11" Gembella's for special occasions.

Nice thing is I have the 89 LSD.

Barry, my rear is big enough!
