What you are looking at is a comparison of how sloppy a stock STI shifter can be after years of use and what an aftermarket Kartboy set up does to tighten up your shifts. No fancy tricks, no blaming it on the transmission - just your shifter linkage.
On this particular display the Kartboy shifter setup being showcased the upgraded components are:
- Kartboy STI Short Shifter
- Kartboy Front Shifter Bushings
- Kartboy Rear Shifter Bushing
- Kartboy Solid Shift Joint
- Kartboy k**b featuring our new topper, trim ring, stainless core, and reverse lockout + boot retainer
We love our manual Subarus, that’s why we make these parts because we drive with these parts. If you’re interested in seeing how you can improve your 5 or 6 speed Subaru, check out Kartboy.com/Shiftkit
