Thickness 10mm Hub Bore 57.1mm Hub Flange 57.1 Bolt Pattern 5 x 100, 5 x 112 Bolt Thread M14 x 1.5 x 38.75mm (thread length) These spacers are new. I checked them for fit on my Audi but they don't fit so my loss is your gain. These should fit most Audi/VWs but you can try before you buy. The bolts are 10mm longer than standard (to accommodate the spacers) and they are a globe seat (not a taper seat).
