The car drives perfectly straight still, and honestly I'm starting to think a tire is out of round or something, I feel it even at lower speeds. I'll check for washers right now.

Weird, before the rims at AM smooth as glass now I have a slight wobble above 50mph.

I bought (4) 17x9 Bullitt wheels from AM and a pair of 17x10.5 Bullitt wheels from AM and all of them were great!

I would double check the balancing first.

+1 alignment wont cause a shake, especially if it drove fine before the wheels tires and springs, just get them balanced.

Well he installed lowering springs and the cc plates could have been moved during installation. I really don't think it's the wheels themselves.

Are you talking about the washers that are put on during assembly @ Ford? Even if those happen to still be on they are not going to cause any vibration.

I'm gonna say one of the rims have a bad balance. I know some guys on SVTP are complaining about all the wheel weights needed on the AM rims to make them balance.
Also maybe one or the tires might be bad I know they are new but it is possible

Is the step spacer installed correctly on the new after marke CC plates?

My old rims from am had a slight shake and never really noticed it until I put other rims on. Glad I went with BBS for my new rims!

Kmelfi got new wheels?!

Wrong. It depends on how bad this wabble is. Do as Moonshine and I are suggesting. Take the wheels off and look for the washer on at least one of the wheels studs.

It happened to me when I got 18" saleen wheels from Cruzin Concepts. I also thought about a balancing issue, using right lug nuts, torquing the nuts right etc. It all came down to taking those washers off. Especially if you know you have stock untouched brakes. Chances are it's still on there.

You would be dumb NOT to check since it's free and only takes 30 min to check all the wheels.

Here, Page 10 post #96....pics are worth 1000 words. These were from Cruizin Concepts, but I wouldn;t doubt if they use the same vendor.
