The A1 chassis's shift linkage can become amazingly loose and sloppy and yet still allow gear selection...IF you have the skills... What's even more amazing is HOW GOOD IT FEELS when you tighten the whole thing up. A SmartShift1 Linkage Kit is your ticket to awesomeness.
All hardware necessary for installation in an A1-chassis car is included. (That means all Rabbit1/Golf 1/Jetta1, both original Sciroccos, and the Rabbit-based Pickup/Caddy with 5-speed*). Also see this excellent SmartShift DIY thread for Mk2/3 which closely resembles the Mk1.
Is it a cruel joke that you're the only person on Earth who knows how to drive your car? Actually, you're not alone. Replace your worn out parts with a SmartShift kit and feel the difference! You'll be amazed. We promise.
For just a bit more precision, go ahead and add an UNDERCAR Bushing kit to your vintagemobile and smile.
Or, for the real deal, go with the GENIUSPACK1 which adds a short shift lever and the highly rated MushMeister, too. For those who simply must have it ALL, the ShiftBase1 is another logical upgrade path. Go for it!
*Note: This system can be modified to work with 4-speed transmissions. The shifter ball and "dog bone" linkages must both be modified to fit.
