Would it be worth going with 3.73 gears? I have an m6 and I was wondering if there would be a noticable difference in quarter mile time compared to the stock 3.42? I dont really want 4.11's because I dont really want to get into 5th gear in the quarter.

One more thing, if I do get gears what all do I need and is it something a local mechanic can do or should I take it to chevy? And what kind of price should I expected for the actual installation? (not the gears themselves)

about 150 for install.....and i would stay with 3.73 4.10 is too much.....think about gas mileage

3.73's are the minimum i'd go with on a M6.
Either those or the 4.10's.
But u seem to be stuck on 3.73's so i say go for it!

Im not stuck on 3.73, I just thimk they sound a little better unless someone can talkme into 4.11. I just want to know if the 3.73 will give me a noticabale difference over the stock gears?

You'll probably spin a bit easier off the line. You won't notice any gas milage difference. You probably won't notice any difference at all, but its a possible .1-.2 at the track.

I'm in the same boat as you, I don't really want 4.10s cause I don't want to shift into 5th in the 1/4, and I do a lot of city driving too. If I had the money, I'd go with 3.73s.

I really don't think you will get into 5th gear in the 1/4 with the 4.10 gear. From what I have seen with 4.10 gears in the m6s you need to trap over 112 mph before you shift into 5th. Also gas milage really won't be affected more than 1-2 mpg and from what I've witnessed effected could mean improve. A BIG benifit with the 4.10s is the less clutch slippage required to get it moving. I think you would be better off all around with the 4.10s.

i went from 3.42's to 3.73's and i could tell a little difference. i didnt lose any gas mileage and i can definately feel the extra pull at upper rpm's.

You dont have to shift into 5th with 4.10s in the quarter.

4.10s = best-bang-for-the-buck mod IMO.

However, if you are planning on doing nitrous or any other power adder, go with 3.73s.

i plan on going with 3.73's as well, but in the future i want to go with a 12 bolt rear-end, so my question is will i be able to use the same gear ratio on the 12 bolt or will i need another 3.73's for the 12 bolt?

You will have to buy a set of gears for the 12 bolt also. The 10 bolt is a smaller diameter gear than the 12 bolt. 7.625 vs 8.875"
