03-07 cts. I have some hotchkis lowering springs sitting in my garage, never installed. Box is very beat up because it's been moved around about 5 places in 2.5 years. Car is sold, never got around to putting them on. A steal at $50 picked up to whoever wants it. I got them back when they were on special for a couple months a couple years back but they were still like $120 shipped but they are not really available anymore I believe. No way I will ship these, the things are heavy. I can meet somewhere within 5 miles of the 1-20 and beltline area.
