hubcentric rings
 

Does anyone know the bore of the car? i think i need hubcentric rings, cause its vibrating like no other.

66.7mm if I recall correctly

Does anyone know where i can get it? Also, if the bore of the car is 66.7, would anyone know what the bore of the iforged rim is? thanks

Iforged should be able to supply you with that data. In fact, they should give you (or sell if you bought your wheels second hand), the rings. I got them when I purchased wheels from DPE. They are inexpensive plastic rings. They probably cost less than $5 to produce. BTW, when your lug bolts are tightened, that should help center the wheel on the hub. Hopefully, these rings do the trick.

What is a hubcentric ring?

Hub centric rings are manufactured so that when they are installed on a vehicle, the wheels are located directly off of the centre flange of the brake drum or rotor. This is done to insure that the outer beads of the wheel are concentric with the wheel bearings. The result is a much truer, better balanced tire/wheel assembly. This is very important with modern high tech suspension systems.

Ynot, thanks for the explaination. I thought that was their function but I wasn't sure.

If I remember correctly, the bore of the Iforged is standard for BMW (sorry dont know the number). Please check your PM, it might help you. Let me know :y
