3.90's?
 

I am getting a 12 bolt soon, and I was thinking about going with 373's or 410's. Most people said to go with 410's. What about 390's? Do you think that is a good choice with a M6 F-body? I have heard that 390's whine bad, but I have also heard that it may have something to do with the person that sets them up ( something about the back-lash ) I really don't know. I wanted to go with 390's so I could stay in the gears a little longer and I wouldn't have to shift as much. Does anyone have any advice on any of these things.

i dont think any co. makes them, or more people would have them

Strange makes them

well, thats 1. why did you post if you can answer your own queston?
