For a long time I've had problems with vibrations in high speeds, the steeringwheel, the keys, everything is shaking...

It starts at around 60-65mph and does not decrease with speed.

I've had my wheels balanced several times, and it only slightly helped.

And now I think I might have found the source, the spacers....

If you look at the pics they seem to be a little uncentered, could this be the problem?

Should I removed the ones currently on the car (fiat originals?) and replace them with a pair of 10mm hubcentric spacers from richie.guy?

Putting the other mounting bolt in should centre it.

.... and yes it will be... it might only be a 1/4 of a millimeter out, but centrifugal force acting on the spacer, it might be 2 3 grammes at say 10mph, but it will greatly increase with speed. like putting as little more weight on one side when your on a kids round about.... your going off mate!

Hope you liked me analogy... =]

yeh id agree. put the other mounting bolt in on the other side, that SHOULD hold it center.

not always the case though

Depending on the wheels 6mm spacers might not leave enough of the hub centre exposed to fully centre the wheel. Wheel studs may help if you have 100x4 PCD wheels but they may not.

To my mind, it's more likely to be a wheel issue than a spacer one.

What are the centre bore and pcd of the wheels?

I don't know much about the wheels, got them with the car but here's a pic (car's jacked up in the front).
It's too dark outside at the moment to investigate, I'll have a closer look tomorrow..
I'll try with another mounting bolt first as it seems like the easiest/cheapest solution... if that doesn't work I'll go for new spacers


Btw can you order them from fiat or should I just try to use some other pair of bolts?

Those wheels are fiat wheels,so fitment wise there perfect. well they may need spacers,my 14"s in the same style needed them, are they 13 or 14"
