Hi guys... My rear pinion seal is leaking and needs to be replaced so I was thinking about putting the TA rear end girdle on while its done... then I got to thinking about the gears and how lots of folks have had real good improvements with a gear upgrade. Now my first question would be what is my stock Gear ratio? I have a 2000 Trans Am (Non WS6) with a 6 speed. My second question is how high, or low I always get confused with that, should I go? My car is MOSTLY street cruised... I take it to a track rental once in awhile but I drive it to the track and home. No trailer queen here. My ultimate plan I guess would be to gather all the parts and bring them all in a box to a local shop and pick up the car with the old parts in the box and the new ones in the car The best pricing I have found so far is from Thunder Racing...
MOTIVE Gears, in your choice of ratio...3.42, 3.73 or 4.10
Or, STRANGE Gears (2 or 3 series carrier) for $25 additional
RATECH Complete Gear Installation Kit
2 Quarts RED LINE Synthetic Gear Oil
1 Bottle GM Limited Slip Differential Additive
TA Performance Rear End Cover Girdle
TA Performance Stud Kit
All that for 459.00 plus 25 bucks if I want Strange Gears. Anyone have good or bad experience with either of these companies gears? The evil side of me want to go for the 4.10s while the good side of me suggests that 3.73 might be better. I'm assuming since its not offerred that 3.23 is my stock gears? Any idea what kind of improvement in the 60' and 1/4 mile I could expect from a 3.73 or a 4.10? Sorry for the long post but I know diddly squat about rears. Thanks.
