awesome info thank you!!

no i don't care so much about the 1/4 mile or 0-60 i don't race. i do like though that you said it gave it some midrange punch as i feel that is where it could use some. coming off my E39 M5 with some mods it is down on tq for me

thank you

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.
