2005 E60 M5 SMG upgrade in Hong Kong
Posted by James Siu on Apr 11th 2016
Just got my 2005 E60 SMG upgrade, very nice upgrade, shifts faster, firmer and smoother, huge improvement on 1,2,3 gears, no more lag between gears.
Even this is not as smooth as automatic gear box, but I can start to use D mode for city drive finally.
