Rear Gearing for a turbo app. I'm getting a 12 bolt in a month or 2 and I wan tot know if I should stick with the 3.42 or go to a 3.73. Will the turbo spool later due to the engine not having as much load with higher gears? I've got an '01 M6 with the STS. Would 3.23 even make the turbo spool sooner?

im running a 373 in mine but i dont know what to use with teh sts set up..dont really follow them to much...
i will probley drop down to a 342 but next season im gonna stick with the 373
do a search on sts and see what other or running...i would say with the sts since its in the rear go with the 373
i did this....installed 3.73...went to track on a friday night....ran 10.16 and 10.17
went home and pulled the rear on saturday and installed 3.23
Next day went to the track and ran 10.12 and 10.14
3.23s are staying
