Four grand's a good price mate.....BUT.....the advise on the Owners club website recommends that you don't go for the cheapest you see (for the usual reasons).
I recommend you read the buyers guide on the GTI-R owners club website (
http://www.gtiroc.com/) and then go have a look.
Have you got the full spec available ? (feel free to email me directly).
Cheers,
Daz
PS When you going to get it dropped then mate ? Those wheels look awesome !
