Having got 18s on my car, I have to admit I like the wheels, but not the fact that they are reps. They are very heavy and have had to put loads of wheel weights on them to get them balanced up.
Having said that, I got them second hand off eBay with virtually brand new Yoko Parada Spec 2's on for a lot less than the tyres were worth. So keeping them on the car till the tyres wear down, flog them off on eBay and then stick the wheels I really want on - the OZ SuperT's currently in the shed.
