Default 4.11s or 4.56s?

I just resently bolt my 10-bolt a the track. So, it's time for a 9 inch. I have the money to buy a new moser 9 inch, 4.11s and locker. But i know a guy that is selling a moser 9 inch, 4.56s, locker, 500 miles( never been to the track).I can get the used one for about a grand less. My question is what are 4.56s like in a M6 f-body? How much of a differents is it from 4.11s? Should i buy the new or used?

Thanks

exactly. 9" gears aren't too hard to change.

Get some nice big sticky tires and the 4.56s will be a good match.

agreed... if you run out of gear w/ the 4.56's go with a taller tire. easier than changing gears.......... i don't think it will be a huge difference on gas since you have the 2nd overdrive.

I have 4.56s. I run with 28in. tires to get down the track. For the street, they are fine IMO.

I have 4.30"s and love them. Hard to tell the difference between them and 4.10's. They drive about the same on the road. Just not much of a 1st gear unless you really wind it up. It seemed to run about 300 rpm's higher at the track. I run a 26" tire. But I also have a 10 bolt too.

The name is Yukon. You can do a search and find a dealer. I just happened that the guy who does my rear sells them. As far as I have seen, they are the only one's that make it for a 10 bolt. I guess there wasn't a big demand for them.
