I went to Home Depot the other day to pick up some tiles. Had 7 boxes of tiles in the back and a few other things and the car turned into a low rider. It even scraped a couple of times on the way home. I've never had the car loaded before, so I hadn't noticed how weak the rear springs are. It's for my 95 Caprice Wagon, which does not have the rear air shocks. I'm looking for a nice strong set of springs that won't raise up the car too much, but won't drop the car when loaded up. Anyone have a good spring recomendation for me? What's prefered, variable rate or regular.
