    I have a 95 Gt with the stock T5 in it.. I put in 4.10 rear gears and now my speedo is way off. Is there a way I fix this? I already have the white 23 tooth speedo gear in the tranny but im still like 10 mph off. Does someone make a speedcal I can utilize? Thanks!

    you can get a speed-cal from dallas mustang. they are less than 100 bux and they are very accurate.

    mine is within 1% with 3.73's.

    it's an easy install too.
