Thanks Tom and MadDAWG. I called Dallas Mustang and ordered the SpeedCal. As well, I shot an e-mail to Tungsten who's got one on his '98GT AODE to help me on the subject a little. A minor detail I forgot to mention was that I recently went from 16" to 17" wheels, so my speed/odometer is off just a tad. Thus, that was also justification for ordering the SpeedCal -- it won't go amiss if I decide not to do the gears.
So in short:
- decide on 3.73's or 4.10's
- find a good performance shop to do it
- install gears along with installation kit to replace existing shims/bearings etc.
- re-adjust SpeedCal to compensate for new gearing.
- find how the tranny shifts with the new gears. If it's acceptable, enjoy the new rear wheel torque, if not..
- start looking for a performance chip.
Am I missing something? Once again...THANKS!
