Ichiba 10mm hubcentric spacers with extended studs
 

Since I went to my new wheel setup, I've been having a very slight shimmy in my steering wheel. As speed increased, so did the shimmy. My first thought was to get the wheels re-balanced since I was running hubcentric spacers. Before bringing the wheels in to get rebalanced, I decided to play around with some stuff last night.

With the front wheels off the ground, you can see the rim wobble very slightly when spun. it was happening on both front wheels (not the rears) so that helped me determine that it's probably the spacers (Ichiba 10mm spacer with extended studs). I'm not running these spacers in the rear.

The spacers themselves are generic, but they have a hubcentric portion that fits into the middle of them. This image best illustrates that:

I've removed and reinstalled these probably a dozen times trying different methods of tightening them down evenly. As soon as the hubcentric portion is there, the wheels wobble. It's both sides as well.

After removing the hubcentric center portion and just running the spacer itself, the wheel now turned true and without any wobble.

has anyone else had any issues with these spacers, or any other hubcentric spacers?

maybe the hub rings arent perfectly flush with the hub and spacer?
