Do ya like them? Where can I get some for the 10 bolt? The 4.10 is just a little to much so I thought I would try the 3.90 gear.

I like my 3:89, but it's in a A4 and it's not a 10 bolt. With tire size I am guessing that all in all it works out to around a 4:10. I would think with a 6 speed you would be happy with a 4:10, but I would get a 12 bolt or 9 inch.

I've got the 3.90's and love them! Still get 28mpg with over 400rwhp and work out just perfectly for my setup at the track!! I've also got a 9'' though and would highly recomend one!!

I have the motive 3.90's as well and over 400 to the wheels. I still get over 25mpg on the highway myself. In town it's just too fun to stay out of it but I think 16 mpg in town isn't bad for what I have.
