I bought the Quickshift Kit from Griffith Engineering in the UK http://www.griff-eng.co.uk for about A$100 and followed instructions from www.206gti.net.
If you guys are interested in installing this, definitely read the instructions on 206gti.net, but instead of a claw hammer, I used a spanner to disconnect the ball joint from the OEM bracket. I just couldn't work out how one can use the hammer!
Now changing gears is a treat!! I've only set it to the middle setting, but it's a big difference to the factory gear change's distance!
