good to know you like the 4.10 for the 6sp. so you noticed a big difference in acceleration?? also is the cruising really not that much higher on the rpm??

thanks alot

RPM is 6% higher and gas mileage is 6% lower, no way around that.

Keep in mind that I'm at 5400 feet above sea level, just South of Denver. That reduces my rear wheel hp by 60+ hp, so the gains that I experience from the final drive change may be more than someone at or near sea level.

I notice a lot more mid-gear responsiveness. It's very noticeable on the street. In autocross I can spin the rear wheels at any place on course.

There's a debate going as to whether your quarter mile time will improve or not. I think your 0-60 and 1/8th mile times will improve, but I'm not so certain in the quarter mile. That's not important to me, but if it is to you, then you'll want to Search some of the related threads and decide for yourself.
