Longer 7th cog + 4.10 rear...
After only a couple of days with the M5, I feel sad that I live in the US. It seems abundantly clear that the car was meant for faster roads. If you hit 3rd gear under acceleration, you are speeding... and we have 7 gears. So, what do we do to enjoy the car a bit more without going to jail and endangering the lives of others in the process?
I would like to know if it would be possible to swap our 7th cog for a longer gear so that we could use a 4.10 (or shorter) rear without elevating our highway cruising RPMs.
This would give us more usable thrust and more gears to play with while staying in 2-digit speeds. As well, highway fuel economy wouldn't suffer, as the engine could loaf at stock RPMs when in 7th.
