i picked up a set of 4 bbs replica wheels for my 320 a while back and just got round to fitting them with new tyres and i get loads of vibration from the steering wheel above 45 50. ive been to 3 differant tyre fitting places to get the balancing checked and done again but all have said that aparently i need a spigot bush behind the wheel, is this correct, of so does anyone know where i can get them from.

on the plus side it looks lush

This is correct, take the wheels on the car to an alloy wheel shop, they will measure the wheel centre and hub and provide you with a set of spigot rings for about £20
