hello people,
have a look at this site if you cant find spigot rings to fit your wheels, this place makes them to order
spigotringsuk.com
if you dont know about spigot rings this place explains it but in brief
99% of aftermarket wheels NEED spiggot rings fitted the other 1% are replica wheels which im sure you wont need to know about
spigot rings can be made of plastic or metal (they both do the same job and neither are better than the other)
a spigot ring fits between the centre bore (inside of your wheels) and the hub on your car
if you get a shaking through your steering wheel at speed (50-70mph roughly) it could be a number of things...... a buckled wheel, incorrect size (they are a very accurate product measured to the point of a MM) or lack of spigot ring
it is an easy thing to check, so if you get this problem, remove a wheel and have a look
i hope this has helped
