I've seen some other vibration issues that occur at various rpms or with acceleration.

I'm having a vibration that is entirely speed dependent. It doesn't matter what gear or whether I'm even on the throttle. It starts vibrating at 85ish and gets aweful by 100. At 100 the car is shaking violently.

I do have a 1-piece CFDS. I've heard of some vibration with them, but I thought those vibrated from 8x-8x mph and then quit vibrating at faster speeds instead of getting worse. Is that right?

It does this on two different sets of wheels/tires.

What else can I check?
