not a great idea unless you either have a second car,6 speed manual or money to burn. Reason being your car will rev much higher at speed,a 3:46 diff will still chew a bit more fuel yet give you a faster take off. If you dont go over 80k's a 3:7 diff could be ok. Basicly if you dont mind a higher fuel cost for a much faster take off,its good.Not being a LSD may prove a problem with un provoked wheel spin a lot

I have 3.7's and LSD in my VS Calais with a supercharged V6.

Best thing i ever done, most performance from any mod ive ever done.

Mine is auto though so rpm at 100km/h went from 1750 to 2100 which is nothing in my opinion. In a manual however it will be roughly 2500rpm at 100km/h
