I went down to evosport today to see how much springs and install would be on my m3. First of all, the guy had no clue how much they cost, and told me 600 bucks for the springs. Then he said it would take 5 hours to install at 85 bucks an hour. I see springs everywhere for 200 bucks or so and install should not run more then 2 hours i believe, if that. 420 bucks for installation is out of my league. Anyone know a place in orange county to install springs? I suppose I would buy them from renn-sport.
