2012 SS convertibele wheel shake

[ArubaToplessSS]

Have 1 inch spacers on all 4 corners.
Went to dealer to replace brake rotors and pads. They refused to reinstall the front stock wheels with the spacers (citing since they are not factory) they will not be responsible if something goes wrong.

Now I have to go to another place to have them installed and balanced.
My question is.... don’t they just balance the wheel and tire?

So, if the spacers, which the wheels are bolted onto, are not perfectly balanced..... could THEY be the culprit?

Anyone has experience with this? And hopefully a solution?

Thanks,

Pete

They'd have to be some cheap-ass spacers to cause wheel shake due to them
not being balanced. That would be like having rotors that were not balanced.

Tires are never perfect. You pushing them out, changes the camber, so they will
ride more on the inner edge. You need to have the camber set for the spacers
as well. They can loosen the top and bottom bolts, and push or pull to change
the camber. You can install camber kits, one cammed bolt in the top hole on each
front strut. Moog has them. There is also a threaded hole in the top of the knuckle,
that you can use a long bolts as a set screw to adjust and hold the camber with the
bolts loosened up. Set the camber with the set bolt, then tighten the strut bolts.
Riding the tire edge can cause wheels shake because of tire imperfections, or
because it's not gripping right being rode on that way.

The set bolt will press on the strut tube, so it is a gentile process...

The spacers are bolted to the hub, and the wheel is bolted to the spacer
