3.7 Roadster will have 6 speed box, I would want to know what the gear ratios were before I tinkered with the final drive
The 3.73:1 axle, too long on 4/4 and +4( in my opinion) on the 3.0 Roadster is just about spot on.
The mph/1000 rpm figures quoted in the handbook are "approximate" - the same speeds are quoted (to 2 decimal places!)for 4/4, +4 and 3.0Roadster even though the wheel /tyre combinations are different
I agree in both points. Ratio is spot on for the 3.0 Roadster. And regarding the 3.7 litre Roadster a six gear box will definitely offer closer gears ratios.
