3.90's for 10bolt??

I just heard Motive is now producing 3.90 gears for 10 bolts. Looks like I'm swappin! 3.90 seems like the perfect ratio.

Let us know how they are at the track. That gear should be pretty good for an auto. Do you drive much freeway?

Thunder racing already has 3.90s for the 10 bolt (3 series carrier). Will these new gears work with a 2 series??

Would these be a good idea for a 6 speed car? or are they still too tall? I like the idea of a mix between 3.42's and 4.10' (3.90s).

Thats what I would like to know. How do 3.90's compare to 4.10's? I can't decide which to get for my m6.

I finally got these.
HOLY CRAP! it feels awesome now, i love 3.90 gears. 6th gear is so usable now all the way down to 1k rpm.

so, for anyone wondering if 3.90s are good, the answer is yes.

Cool that's what I've been waiting for. I've already done the math and the 3.90s work out excellant for off drag strip use, since 4th gear is useable all the way up to roughly 120, versus the 4.10's 112, which is handy for road courses. Just wanted to know if the actual pick up increase was worth the cost. Have you run any times yet, and is 1st gear still useable?

Maybe I should clarify...
by 'these' i meant the moser 9" w/3.89s (3.90 whatever) i had mentioned in my previos post. sorry for any confusion.

To buy them, just get a moser 9" and ask for 3.90s.

i haven't been to the track yet, i just finished the break in period for the gears. I hope to go in a few weeks.
