Ok, but when your times start to suck because you have to shift into OD, I hope you have enough money to go back to a 3.90 or 3.73. I'm sure 4.10's are fun on the street, but they just aren't a good gear for 1/4 mile racing.
With 4.30 Gears 3rd gear ends at 104 shifting at 5800. (101@5600)
With 4.10 Gears 3rd gear ends at 109 shifting at 5800. (106@5600)
Too tell you the truth I don't wanna be swapping out gears when my car gets faster. Right now my car already traps at 103 and I really don't want to be running out of gear. I still say 3.73's or 3.90's for an Auto.
