For those folks who have upgraded their gearing. Do you think regret getting the upgrade w/o getting the limited slip as well? DO you find the DSC coming on while launching from a start or accelerating out of the corners? I am considering a 3.38 on my 2003 330i (6 speed, No ZHP in Canada so 2.93 final drive still).

Do guys think that not including the LSD discounts the worth/enjoyment of the upgraded gearing?

If you do a lot of power launches you might enjoy an LSD... also, as a practical matter, if you drive in the snow, you might want the LSD for better traction on the slippery stuff.

I'm going to do a 6-speed conversion, and get a 2.93 LSD if I can find one-- I'm more interested in gas mileage and longevity.

If you're considering changing your diff, might want to look into the Quaife, as a lot of track guys I know have them and swear by them:

DSC comes on every now and then with my 3.38. Normally DSC is off though. I mean if you are trying to launch hard from the beginning, it would make sense to turn the DSC off anyway, right?

I just upgraded my gearing from a 3.15 to 3.46 yesterday. I don't regret not getting the LSD. I don't know what your ultimate goal is for upgrading your differential. Is it to just pick up more speed, or is it to transfer the power between the rear wheels?? I wanted the diff to pick up more speed and my 3.46 definately did the job. If anyone want's my diff it is for sale.

Just looking for more acceleration but without a whole lot of spinning tires.

i know that you have a open diff right now in your 330. when you launch off the line how do you feel about the wheels spin? When you swap for a more aggressive gearing with an open diff, you should feel the same amount of wheelspin you have currently.

I thought increase torque to the ground will increase wheel spin
