Turn In Concepts Super Solid Shifter Set - 2004-2021 Subaru STi

With the introduction of the new Kartboy solid linkages, the TiC team has come up with a kit update. So, here it is, the STi Super Solid Shifter Set. This kit is made up of five parts. The KB STi Shift Linkage, the Kartboy Front AND Rear Shifter Stay Bushing, the Kartboy Shift Lever, and the TiC 6MT pivot bushings. If you need the Tallboy version, click HERE!

To understand how this works you have to understand what each part does. The OEM setup uses a rubber-isolated joint that wears over time and absorbs shift input instead of transferring it directly to the transmission. The Kartboy solid shift joint replaces that factory assembly with a precision machined solid connection for a more direct and consistent gear change. The Kartboy solid shift joint features solid stainless machined center cross tubes, press-fit bronze bushings, and precision machined stainless crush tubes for a bind-free design while still allowing proper bolt torque - this is a component built to last. If this is too much NVH for you, then there is THIS kit with the TiC linkage bushings instead

The Kartboy Front and Rear Stay bushings replace the two soft rubber stay bushings that come stock on the car. There are two hard mounting points for the shift lever assembly, and Subaru (for some unknown reason) decided to use really soft rubber for each one. The problem this creates is a vague sloppy feeling in the fore/aft motion of the stick which just leaves you with a blah feeling when you shift the car. Kartboy's bushings fix this by using a much stiffer urethane to replace each one making the shifting experience much better than what you are used to. Each gear will snap into place with a nice positive click, and that vague feeling you get at the end of the stick travel will be gone.

The Kartboy STi Shifter Lever for the Subaru WRX STi 6 Speed is the first non-Subaru version available. With a height reduction of 1" and a redesigned mechanical advantage, a throw reduction of 40% is achieved. CNC machined and Tig welded in the USA. Matched with the bushings above, a major improvement in the shifting is immediately felt, while retaining the factory reverse lock-out. The TiC 6mt pivot bushings are pre-installed with these shifters, so no need to worry about getting them in there yourself!

When you combine these bushings with the lever you get a shifter setup that just begs to be snapped from gear to gear, and makes your entire driving experience much more enjoyable. Don't yell at us if you get tickets because you just can't resist snapping through the gears. The TiC x KB Tallboy shifter is also available, scroll up for the link to that!
