Glad you're happy with your c/o's.
Both of your spring/shock combos were incompatible. HR springs require a damper like Bilstein sports not HD's or Koni sports. I haven't seen any glowing reviews of HR springs on these cars regardless of damper selection. HR should provide shorter bumpstops with their springs.
