I think the 3:90 gear is for hard core racers that want to meet an exact rpm through the traps.
Probably when 3:73's are still not enough gear and the 4:10's are too much.
I think 3:90's would have been better for me than 4:10's since I run a C-4

do you NOT care about gas milage? the choice is simple, if you drive highway and dont make 20 bucks an hour, might just go with 373's, in town driving or dont care about mileage, 410's............ ITS SIMPLE!!
