It's good to hear that it is not necessary to pick between the two. I guess I was just worried that the combination of the two would make redline come so quick that 2nd and/or 1st would be a waste. Thanks Adam!

it wouldnt be a waste because the mph will only be down about 6 or so mph depending on which gear your in. As long as you have good traction it wont waste anything at all.

Would this be a bad idea for a mod, if I drive mainly just on roads? Dont do any tracking (yet) but would still like to get the best performance out, I just dont want to sacrifice and get a shitty DD.

^ I was curious about the same thing. My 240 final drive was 4.083, but the reason that wont work is because the pinion size is different. Nice try though...
