Car squeaking after lowered

This weekend I lowered my C6 on stock bolts. I bottomed out the front and cut the bushing off the rear. Now it's making an annoying squeak at slow speeds over bumps. Is that normal? Is there anything I can do to fix that? And is it bad for the car to no longer have the bushing. There's still a little bit of rubber on the bolt but isnt it mostly metal on metal?

If you cut the bushings, you may have the metal part rubbing on the spring, thus the noise.

I had the same issue. I simply sprayed the rear sway bar clamps and the bushings I cut with a silicone based lubricant. Drove around the block and I've never heard a noise since. I'd try that before taking everything apart just to change bolts, especially if you already re-aligned.

I put a dab of grease between the rear (cut) bushing and the lower control arm. Haven't had a squeak problem yet (6 months)

I really appreciate the input. After work I sprayed some white lithium grease on it. Squeak is gone. Hope it stays that way. I may buy a set of those pads to keep around the house just in-case.

Hang on a second. I think everyone is missing the big picture. If you removed the rubber bushing from the rear bolt then you now have a steel bolt rubbing on the aluminum control arm. NOT a good situation. A little lube may stop the squeak but that steel bolt is still going to cut into the aluminum A-arm. Look into the lowering bolts from Hardbar. They use a delrin end which is self lubricating, will take forever to wear out if at all, and does not squeak.
