Default STi short shifter review.

This weekend I install the KartBoy 6spd short shifter. Prior to that I had install the factory STi short shifter. The factory STi unit is the stock height, and about a 10%-15% improvement on throw. It is an improvement over stock but not huge. Fast forward to the K-B unit. It is about 1-1/4" shorter in height and about a 30% inprovement (over stock) in throw. The feel is great. This is what I was looking for in feel and motion.

My advice, don't spend $325++ for the STi unit. Save big $$ and get a better shifter, buy the KartBoy.

Are you saying that the KB is 30% shorter than the STi short shifter or the regular STi shifter? How much stiffer is the shift with the KB. I love the way the STi short throw feels and wouldn't want the gear selection to be any more firm.

Thanks,

Fess

from our website

The latest in a series of firsts. The kartboy replacement 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 a set of kartboy shifter bushings (available separately), a major improvement in the shifting is immediately felt, while retaining the factory reverse lock-out.

still a few sets left from the first batch.

Best estimate is a 30% +/- shorter throw over stock. About double what the factory STi replacement gives. The shifting feel is very precise. I wouldn't say that it is stiffer but more precise. I have a Pro-Drive knob on mine the the actual length difference was 1.25". Height is just right for me. If I feel lazy I can go through all six gears with only wrist movement. My arm stay stationary.

The install was very easy. I already had the stock shifter out so my swap was done out of the car. Doing the swap without removing the assembly would be much more difficult in my opinion.

Hmmm, well as of right now I'm very happy with the STi short shifter. Maybey next Spring after I'm used to it.

I might just have to do that Tom. I was very pleased with the results in my WRX from the STS and bushings.

In another thread, Tom at Kartboy states that the KB SS has about 15% shorter throw than the STi unit. I believe that this means that if KB throw is 30% shorter than stock, the STi unit has 30% / 1.15 = 26% reduction of throw relative to stock. So the throws are fairly comparable. (Measuring the pivot points of both designs yields similar conclusions.) The main difference with the KB is the overall lower height.
