2.45 gears? You sure U really want those--that car is going to feel like 6,000 lbs taking off from the light. Oh sure, @ 75 mph it be OK, in fact really nice--problem is getting up to speed. It would be OK in 75 mph zones were you can go 85--90 and 2nd gear would be 3.55 so it pull to 125--130 nicely--once its at 90...
traffic sadly doesn't move that quick up here
