After a gruesome 5hr. UUC short shifter install on my neighbor's m3, i've decided that its time the lude got one. So far i know of three: Pure Racing, DC Sports, and Neuspeed. Is there one i should be gravitating towards more? Do they all have the same reduction? I was looking around and i heard the neuspeed is about 20% and the DC sports is somewhere between 30-50%(heard all different answers) Looking for guidance here!
