16x8 Porsche (OEM) 'Winter Wheels' purchased new for current use on daily driver.  Original optional equiptment for the 928, I purchased these new in the factory box for $150 each.  Currently fitted with 225/50ZR on front and 245/45ZR rear.  Tires have a nominal amount of wear and many miles left on them.  CRESTED Center caps are factory parts.  This set is currently on a 1988 Porsche 944 using 25mm turbo adapters (originally purchased from Automotion) to adjust the offset on the rear axle.  Will sell adapters with rims if requested by purchaser.  If your looking for a unique 'factory' upgrade to 16" wheels, this setup has worked exceptionally well for me over the past two years. Buyer pays shipping.
