I thought this thing rode a bit lower than stock and I just checked out the springs up close. I knew it had the sls delete already but I found H&R springs up front with Dinan springs out back. As best as I can determine one of the PO’s found out what springs dropped the car the most and went with them. Well the dinans are rusty and the H&R’s are getting replaced too, because I bought Spax springs and dampers. Can hardly wait till next weekend when I can install it all.
Update: as it turns out spax springs are the lowest in the industry for this model. They are so low in fact that they scrape my exhaust going in and out of my garage. Fortunately e28.com is a great bunch of guys and I got a set of Dinan copies from Paul over there for just the cost of shipping one way. (Im shipping him the spax in trade).
