Re: Desperate Help Needed !
Thanks for all your help. As far as I am aware, the 155 came with spacers as standard at the front, which I already have on the car.
However, the wheels are beginning to baffle me - they are five spoke, with Alfa Romeo centre caps and Alfa Romeo stamped on the inner rim - but the dimensions of the spigot ring I needed was unusual - inside diameter = 51mm, outside diameter = 77mm - and suprise suprise, nobody stocks them.
The wheels as far as I am concerned are standard Alfa ones - they are identical to the wheels fitted to the Silverstone edition, just metallic and not black, but they are 15" x 6.5J.
What the garage had actually said was that this spigot ring had crumbled away - which could be true as it is only made of brittle plastic! I just guess I will have to get them machined down in metal, probably an advantage that way as they are less likely to break up!
