I got Ron Stygar's clutch stop today in the mail...took all of about 30 seconds to install (perhaps the easiest mod on the planet). And man, what a difference! Why oh why did BMW not build the car like this! The decreased clutch throw is such a godsend! Shifts are done in less time, are more precise, and require less effort. It provides an even more sporty feel to the car.
To who ever doesn't have a clutch stop yet...send Ron and e-mail and get yourself one ASAP!
