Buy this kit! I bought it as a poor man's shifter upgrade for my Rallycross mk2 GTI. I was losing precious time trying to downshift into first with the sloppy stock shift linkage, even after a complete shifter box rebuild.
The installation isn't a 15 minute job. It's difficult to get your hands and tools into some positions where you need to tighten everything up. Keep working at it; it's worth it.
Wow, what a difference! Shifts are accurate and precise. You can feel a positive "notch in" when you get a gear. And the gear positions are right where I set them when I adjusted it the first time. It's held up great in the Rallycross car over five sessions so far.
