Afaik there are 3 systems for spacers available

Spacers without centric ring - which i never would recommend - but afaik there are no 5 mm, or 10 mm spacers with centric ring on the market - o.k. german market



Spacers with centric ring - up from 15 mm.



Spacers with centric ring and a so called DRA system. With this system you can use the stock wheel bolts. The DRA system comes with his own wheel bolts.



But as said before, centric rings won't help if the bore radius is bigger than 66.5 mm.
