Love that review mate, bet the car flies now!! What HP do you rekon she is now? If she spins in 4th @ 60mph, she must light em up big style in 3rd.
Also I am not 100% sure but the gearbox in the M5 with SMG is exactly the same box for the manual cars in the US.
This is 100% the case for E46 M3's regarding the SMG & manual boxes. The only difference being one has a pump and is hydraulicly actuated rather than a manual with a clutch.
