3.73 or 4.10 i broke the rear end about a month ago and had it replaced with the same 10 bolt rear and now its giving me problems already. i brought it back to the mechanic and he said he would check it out this week. SO i was thinking about swapping out some gears if he has to pull it all apart..... what kind of quarter mile time can i expect out of a 3.73 or 4.10 from a stock M6 01 SS? also what will the car top out at with different gears? what can i expect to pay for something like this and how will this effect my speedometer? thanks in advance
Well I just installed a spare 10 bolt with 4.10's today. I have not had the speedo recalibrated in the ECM for the gears but 3rd and 4th gear feel totally different when you get on it, I just don't know what speeds I am shifting at. My setup on 3.42's I was shifting out of 3rd at 110mph at 6500. I should be pretty deep into 4th gear now at 110mph.
A 10 bolt is a time bomb anyhow which is why I still have my stock Zexel in the shed. That being said 4.10's get a huge thumbs up on an M6 car. How long they last in your car depends on driving habits and gear setup but its still a crapshoot.....

If your gonna spend the money to change the gears, go 4.10s. You'll be able to hit around 115 in 4th gear, which is perfect for a strong running bolt-on car in the 1/4. If you add a cam and raise your rev limiter, 4.10s will work well with more power as well. Don't even consider the 3.73s.
Oh, performance gains...
I was running 12.50s with the 3.42s and bolt-ons with Nitto DRs. I installed 4.10s and started running 12.30s. Getting off the line is what the gears helped with the most. I did trap my highest with the 4.10s however at 113.xx vs a best of 112s with the 3.42s.
