Just finished installing new bilstein sports with stock springs in my ITR yesterday. I took it out to make sure everything was ok, but it's NOT, *cry*. The rears have a huge lumpy feel to it. It'll flop, flop, flop every 2-3 seconds and the whole rear will bounce back and forth. What did I do wrong? I've installed shocks before with no problems...and I double checked my work and there doesn't seem to be any problems. I plan on taking everything apart and reinstalling it tomorrow, anything I should look out for?
