The eaton is an ok differential, but i'd look into a Detroit Locker. I mean you've got to be making some mad horsepower with all those gauges <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> First don't you want to buy those 20's to really increases your 1/4, I mean literally increase.

 

I have had a Detroit and they are badass. Had in my old car and wish I had one in my truck. Right now still limping with the G80.
