I did that. I also got the shorter bumpstops to go with them. But they really are too stiff for the stock shocks, so it's not a perfect setup. Springs are underdamped with the stock shocks. I'd go with either the Koni yellows or Bilstein HD's. I'm leaning toward the Bilsteins, especially if I can find the Adjustable 10's that show up in the european catalogs. I'll be needing to do this soon so the springs are happier.
