I've read where tons of people are swapping over to the 3.92 because of this very issue. I may be looking around for a rear end shop very soon.
I'll keep you posted.
No such thing as stock 21" rims. If you have 20's, they were dealer or owner installed, from the factory 20" rims are paired with 3.92's.
