Well, Yes & no...
Basically you could hunt for any 4/100 rim. VW has a CB of 57.1 This is among the very smallest one on the marked. Meaning should your rim have a bigger CB, U need spigot rings.
4/100 will come off plenty smaller Audi`s, VW`s up to mid 90`s, Opel/Vauxall, BMW up to E30 (early 90`s) just to name a few sources. Really not THAT hard
NICE build btw
