So even more good news.
Ever since doing the camber kit, I've noticed a "clunk" every time I hit a bump on city streets. Don't really hear it on the freeway though. Took it back to the same shop and they're telling me I've got a bad ball joint or tie rod end. Sounds like a hell of a coincidence, but it is possible that the stock rubber isolator on the strut mount was masking the sound. The Maximum Motorsports mount uses a spherical bushing. The car does have 120,000 miles on it.
Lame.
