This kit is designed to turn the OEM FK8 shifter into a finely tuned piece of machinery. The shift cable bushings and shifter base bushings help to remove unwanted compliance from OEM rubber bushings to help remove flex while improving tactile feel. The upgraded centring spring helps to make quicken centring action for a snappier feel while removing unwanted lateral play while in gear or in neutral. Consider adding a shift knob or shift boot collar to further customize the look and feel of your shifter.
Note that use of a flat-bottomed knob on an FK8 requires use of an aftermarket shift boot collar (like the one sold below) to have the shift boot clip to the bottom of the knob properly. This is due in-part to the unusual design of the underside of the stock FK8 shift knob.
