I recently purchased a set of BBS RX, 18 x 8, 5x112 alloy wheels from ebay and the spigot rings that was present in the wheel are the wrong size for my car, although the seller said they would fit 8P chassis. I've put them on the car anyway but i'm suffering from vibrations as if the wheel is unbalanced, especially at higher speeds, which feels unsafe. The code on the current ring is 09.23.445.Ã57 Can anyone advise me on where to get these original BBS items? Ive searched the net and cant seem to find anywhere that stock them. I know theres loads on ebay but they are the plastic type and I'm not sure they will be sufficient. Any advice appreciated, thanks in advance.
