Hi guys, I'm currently looking for some replacement 18" alloys for my facelift Focus ST Mk2. On ebay I find a number of (seemingly reputable) sellers offering ST 'style' alloys for ~400 quid for a set of 4. Also on ebay and elsewhere I find 'genuine' ST alloys for ~200 quid per wheel, so twice the price. I notice there are slight aesthetic differences, but what else can be attributed to the 100% price difference? Are they made from different materials? Are they heavier? Are they liable to having/developing defects? Will they affect the resale price of the car? Thanks in advance for your advice.
