The ACS short shift kit is not available yet.
According to CEC, it is due out anytime now.
Apparently, the ACS 540i 6-speed kit will not work on the M5 or atleast ACS is making some mods to it.
Try to contact Emil Schmid in Switzerland. His email address is [email protected] He does this for all of the BMWs, Alpinas, etc. and can do everything between 6 and 9 cm shift. You can use the original gear knob.
