When I got my new wheels they came with 1/4" spacers. I tossed them on and figured why not. Lately I've noticed a slight pulse/vibration in my gas pedal and floorboard from 15+mph. The spacers don't fit well on the lugs and it shifts around before the wheel is put on. All my lugs are torqued to spec but i'm wondering if since the spacer isn't centered that its actually causing a bounce when at speed?


Anybody recommend anything else to check? Saturday i'm going to remove the spacers and see how it does. Mainly curious if anyone else runs small spacers?

 

Junk them. If you're going to run a spacer (dont) make sure it's hubcentric. you know when you put your wheel on and that large middle hole sits nicely on top of that proud part of the hub? That's hubcentric. Running a spacer that's not hubcentric can lead to balance issues as you've essentially installed a giant unbalanced weight onto the rotating mass of the driveline.

 

most of those spacers that come with wheels aren't hubcentric which Prismatic already explained... the "universal" POS spacers are all kinds of screwed up.

Take the spacers off and mount the wheels without them, or go out and get high quality spacers that are 100% hubcentric and you'll be much happier.

 

What they said. IMO I would not run them at all.
