My GSR was running with stock tires & rims with 20mm HR spacers. I put those spacers when I lowering the car with KW V3 about 2 months ago. But after that I noticed the pretty significant vibration from steering wheel after 80 MPH. At first, I thought it was tire balance issue. But this morning, I took the 2 front spacers off, and the vibration is gone! Car drives stable and smooth even 90 MPH.

Are the spacers hub and wheel centric?

Who drives 90

Use to run HR 5mm spacers & had the same vibration issue. They were not hub centric but so shallow that I could still center the wheel on hub pilot

should be. they were installed by a professional local tires shop

just because a shop installed them doesnt mean it was done correctly, you have to make sure that when the spacer sits against the rotor it does not wiggle around on the hub, i needs to sit flush and snug to make sure its perfectly centered, i have garage line spacers that i run with the stock mr bbs wheels and ive done over 140 mph with absolutely no vibrations.

Whether or not they're hub centric also has nothing to do with who installed them...
