Ive got a question thats been bugging me ever since i brought my car, wondered if anyone could shed some light on it for me. i drive a 89 8valver, and the wheels on it are 14" BBS style wheels made by TSW. however the Internal bore or the wheel is the same as any OE alloy, so no spigot ring required. i wondered if anyone had seen anything similar, or knows if this was some kind of a factory fit alloy?
