Diff Gears

[gt3540rx]

your car sounds like a beast..... Im going to be making around 100rwkw less.
It doesnt seem like changing to 3.45 ratio will really affect highway fuel economy much...how much extra acceleration would the diff upgrade achieve?

More like 400 lol

I have the 3.27 and it's perfect in my opinion.
