I bought mine here https://www.justforwheels.com/index.jsp

Believe me i had 5 sets of wheels which were all supposed to be hub centric but were out by a hair but it was enough to cause vibrations which drove me insane because i switched rims, tires, multiple wheel balances without any progress and everyone blamed the rim, tire or last place to balance the car. Once i figured this out i cured my vibration problems and mutiple road force balances were a thing of the past. My steering wheels is super smooth now without any vibration.
Hey thanks for your suggestion. I'll have to try the hubcentric rings.

Indeed the centerbore on the Apex wheels is 72.6 and the e90 M3 centerbore is 72.5
