Gears & Axles - 3.90's or 4.10's

I'm sure this has been beaten to death like my ...... Just picked up a 2002 WS6 M6 and I am doing a gear swap. Big difference between 3.90's and 4.10's? One better for HWY/FRWY driving??

Thanks! Elliott

What are your plans for the car? I wouldn't swap gears on a 10 bolt, save your cash and buy a niner.

I plan to put 3.90's in mine..with a 26" Tire I will run out of Gear with 4.10's.

I've got 3.90s and a 28" tire, I'll be spraying at the track. Should be plenty fine gearwise on my part. They're pretty nice on the street as well.

I'm gonna track it just a couple times and call it a day. It's gonna be more for show and around town play. The nine inch would be nice but I'm hoping to make the 10 bolt last. Plus I have a spare 10 bolt w/ 3.73 in case.

Elliott without a doubt do 4.10's. Try and find something with the GM 4.10's they're supposed to be very very strong gears and don't typically whine. I love M6's with 4.10's. Nothin like it.

you're running an A4,typically 3.73s' are used with A4s'. You'll be one of the brave that go above 3.73 with either a 3.90 or 4.10. I'm 4.56s' with A4 and love it.

Different car as specified in my original post. I currently own a 2002 WS6 m6.

M6 then for sure 4.10s'.

I wouldn't want a gear higher (numerically lower) than a 4.10 in my M6. Definitely go with 4.10!

Looks like I'm going the 4.10 route. Your boy want them LPP's Fergy??
