New gear
I do believe a 4.10 gear change would involve a new 4-series carrier also right? If you already have 3.23's from the factory any option is fine in the 3 series. If you have the 2.73's, you have to step up to a 3-series carrier also.
concerning our little 7.625" 10 bolts,2.73s' and 3.08s'(V6) came on a 2 series carrier,3.23s' and 3.42s' came on a 3 series carriers.
Gears for a 3 series carrier are available in 3.23s',3.42s',3.73s',3.90s',4.10s',4.10s',4.30s',a nd 4.56s'.
Gears for a 2 series carrier are available in 3.42s',3.73s',4.10s' as 'THICK' gears.

if its auto get some 3:90, 4:10(if you dont care about economy) if its 6 speed then get a 3:90 at max. a buddy of mine did a 4:10 swap form 3:23 and he lost 4 tenths at the track because of traction and shifting more often. he had a manual

^ this makes no sense. a 6 speed comes with 3.42's stock and 3.90s imo are perfect for a 6 speed but people do run 4.10s in ls1's with much success. I would prefer 3.90's but the op would have an issue with a t56 and 4.10's and would easily improve his times.
I would not want 3.90 in an auto as theres no point. Gears in an auto do very little for track times unlike an m6 the stall and slip in an auto hides the gear. If the op has an auto 3.42 or 3.73 will work great for a dd/track car and then adding a nice stall will wake it up. Low gears with a converter will only tighten it up and wont do much for track times.
