This guide covers a full shifter linkage replacement on a GC8 — short shifter, pivot bushings, front and rear shifter bushings, and the new Kartboy Solid Shifter Joint with the 5-speed clevis. If you're only doing the joint and clevis on other 5 speeds, the shift joint portion still applies.
This guide covers installing the Kartboy Solid Shifter Joint on a 6-speed STI. This install is done on a 2004 STI but applies to all 6-speed STI applications. If you don't have the full suite of Kartboy shifter components already in your car, It's night and day easier to do it all at once. Whether you have the setup already or stock components, this guide shows you how to swap just the joint regardless of what you currently have.
This guide covers installing the Kartboy Short Shifter on 2015 and up WRX cable-shift transmissions. This install is done on a 2016 WRX but applies to all 2015+ cable-shifter applications. Everything in this guide happens underneath the car — you're swapping the shift plate on the transmission itself.Kartboy also offers this shifter as a combo with the Cable Shifter Lock, which installs from inside the cabin into the selector mechanism and further tightens up neutral-position slop. That's a separate job covered in its own guide — this one is strictly the under-car install.
