    Kartboy Shifter and Bearing Kit ( Part Number: KB-20-WRX)
    Well made, works great 12 months ago
    I had a Kartboy shifter in my first WRX, an '02 I bought new in 2001, and loved it. Glad to see their quality is still top notch. Everything went together perfectly. The throw is incredibly short and precise. Huge improvement over what was already a decent shifter. Thanks to RallySportDirect for the install video. It was very useful since this kit came without any instructions. That would be my only knock, instructions would be very helpful.

    If you have made it this far, Do It  1 year ago
    This is the type of mod where having the right tools helps tremendously. 3/16 roll pin punch and a pneumatic palm nailer both from amazon and this took like an hour, maybe less. This alone makes the shifts nice and tight front to back. Combining this with a shift stop, a transmission mount, and maybe a heavy shift knob (preference) really makes things awesome.

    Fantastic 1 year ago
    Awesome upgrade, especially with the Cable Shifter Stop. The plate install is entirely under the car and you have to remove a bunch of stuff to get to it. The only difficult part is the pin that you have to hammer out with a punch. Make sure you get two punches of good quality because it's REALLY hard to get that thing out. You can fit a 7/32 punch in there, but 1/4 is too big. The punch will start to mushroom a bit, depending on the quality. Seems like I hammered that thing out for close to an hour. Putting it back in isn't as bad--just make sure you watch a couple videos on the install first. This plate weighs probably less than half of the OEM plate and it creates a nice, stiff, notchy feel that you will love. I'll probably experiment with a heavier shift knob just for fun, but it's really not needed.

    The best mod done to my car yet. 2 years ago
    Normally I don't do review, but I felt this kit was worth it. It makes the stock shifter feel better and shorter than the sti short shifter. The build quality is top notch and the install was straight forward and easy. At first its it seams hard to shift, but and you get used to it and will love it. You wont regret this purchase.

    Works Good! 3 years ago
    There are not a lot of detailed instructions for this part. The two washers, nut and bolt are used to press the bearing into the shifter cable eye. You will need to remove the front transmission cross member to gain access for punching the roll pin. when you apply the bearing to the lever, remember to remove the bottom bolt for the lower shift cable bracket and loosen the top bolt on that same bracket. This will allow you to move the shift cable enough to slide the bearing onto the shift pin with ease. Otherwise you will be trying to install it at a slight angle and will not go on correctly. Now... This part feels pretty damn good. My first mod on my 2016 WRX and many more to come.

    • Q: Bearing  Matt10 months ago

      Is the bearing in this kit the same thing as Perrin brass shifter bushing PSP-INR-016? Also, does Kartboy offer this kit without the shift stop for those of us with a different unit?
      • 0 of 0 people found the following answer helpful

        A:  The bearing included here is not the same as that Perrin Bushing. To purchase the kit separately you will need part numbers: KAR KB-003-B , KAR KB-003LOC

    • Q: Shift stop?  jjscrivener11 months ago

      Does this kit include the Kartboy shift stop? It's shown in the product photo, but not listed in the description.
    • Q: Perrin shift stop  vash_241987728642 years ago

      I have a Perrin shift stop installed, would it cause any problems with the kart boy shirt shifter?
      • 0 of 0 people found the following answer helpful

        A:  This would work well in addition to Perrin's Shift Stop and there will be not issues/problems.

    • Q: Does this shifter replace the same part as the Perrin short shifter adapter?  fordtruck763 years ago

      Does this shifter replace the same part as the Perrin short shifter adapter? Does one function better than the other?
      • 0 of 0 people found the following answer helpful

        A:  This is essentially the same as the Perrin adapter. Both work quite well and will have similar performance.
