When I bought the car it came with white 14" Enkei's on it.

These are the tyres I am now running (205x40x17), I was skeptical at first, but after having them on for a week the change was amazing! the grip was increased and the wet weather grip is just awesome!

The Enkei's have since changed to a set of 17" CSA Technic's, but instead of the CSA center caps I had carbon fiber look ones made with GTi written in silver.  

I've also put on the front, a pair of DBA cross drilled and slotted discs, but I still have standard pads in it so the disc upgrade does nothing for performance, it's more for looks.
