You are right, missed the desc
"Seat Style: Ball Seat 14mm Radius (R14) With Spin Seat Design". From the picture they appeared to be something different. Late night, red eyes and all..... Apologies.
The spacers above and lug bolts seems to be fine. Actually I just browse at this eBay seller's stocks and I'm thinking about going for a set of his 'rust proof' black zinc plated lugs myself - I could get rid of my cheap black plastic caps I'm using to hide the OEM crappy & rusty lugs that Porsche puts on their cars.
Thanks for the link
