I've got 18's lurking in the garage, they are in decent condition, the balancing weights have gone rusty, and they could do with a clean. Tyres are Nexen with decent tread but are probably over 10 years old now. This thread shows them on the car.

you can have them if you want to organise and pay shipping costs
