Need Advice From M6 Guys who 3.42 to 4.10 I done a ton of searching about this, but couldn't come up with any concrete answers. I need a new set of gears in my 00 WS6 M6 10 bolt. The stock 3.42's are making a lot of noise and are really worn. I cannot decided if I want to go with the stock 3.42's again or go with 4.10's. I hear a whole lot about how the 4.10's will make the car feel totally different and it will accelerate like crazy. Sounds nice, but I want the car to "physically" accelerate faster and be faster, not just "feel" faster. I have heard a lot of people say that they do feel faster, but when taking it to the track or racing it out on the street, they see no difference. Are there any of you out there that has some runs with your 3.42's and then ran again after your 4.10's? Did it make a big difference. I want some concrete evidence, showing that the 4.10's will or will not "physically" make my car accelerate better, not just feel faster.
It was one of my favorite mods in my M6. No way I would go back to 3.42's.

Whoever told you that they don't run faster at the track is full of ****. It is proven that with traction you will run a few tenths faster on a track with 4.10's.
I have never switched from 3.42's to 4.10's but have when 4.10's-> 3.42's. (broke the 4.10 rear end and replaced it with a stock 3.42 rear, that just broke a few weekends ago) When going that route I noticed a HUGE difference, even in my times. I was noticably slower in the 1/4.
Go with the 4.10's and don't look back.

I picked up 4 tenths when I made the swap. I never broke the gears, but I did twist the driver side axle with some et street dr's. 375 rwhp cam + bolt ons ta. When I found a 3.42 rear for cheap, the car did not have the nice low end it used to. If I had to do it again, and I didn't drive much, I'd go with 4.30's. But, the 4.10's still got 25 mpg on the highway before the cam vs 28 mpg with the 3.42's.

I went 3.42 to 3.73 and then to 4.10. I like the 4.10's the most simply because how fast you can run through the powerband. I picked up .15 with stock internals so I'm guessing a cam'd car can pick up .2 to .3 since they will thrive off them even more.

Believe it or not I got better traction on DR's with the 4.10's than I do with the 3.42's. I used to be able to launch like hell out of the hole with the 4.10's and now with the 3.42's I spin BAD.
That is why the S60 will have 4.10's. And when I spray the 150 shot I will just step up to a 28" tall tire.

I have ran 3.42, 3.73, 4.10 and 4.56 in my 6 speed 98 Camaro. 4.10's are a great gear, if you add nitrous you'll need to go to a bigger tire once you start to get close to 120 mph. You can jump to a 28" tire to drop the rpm some, if you have more cam then you can rev it on a 26" tire.
If you go with a big cam and get closer to the 7,000 rpm range you'll be better going with more gear than a 4.10.
Either way 4.10's will make the car faster, as far as people putting in more gear and having traction problems, that's just what happens when you don't know what you are doing with the suspension and tires.
One thing is the 4.10 is a weaker gear, the teeth are actually smaller and will break easier than with the 3.42. If you want to go fast, race the car, add power, save yourself the time and money and invest in an after market rear end, the stock 10 bolt is a pile of crap.
