Talk to AaronC, he runs them. If 3.90's were out when I got gears done, I would have picked them over 3.73's any day.

I have them and they are cool. I got them because they're a good "tweener" gear. I had 3.55's before and hated them. I'm more of a dragstrip person and they were'nt good drag strip gears. I got the 3.90's because I plan to use nitrous and race NA. It was a compromise for both applications.

i would agree on that.
Never used them, but i wouldn't buy 3.73's over 4.10's cuz they're just not enuff.
On the other hand 4.10's are a bit steep for long drives, 3.90's sound perfect to me

I believe the company that makes the 3.90 gear is called Motive.
