I'm having a problem. After I land a jump the truck bottoms out and bounces several inches into the air. This wouldn't be a problem except sometimes it bounces so hard that the truck flips onto its lid I get some pretty big air about 10-15 feet into the air and 20-30 foot distance.

What do I need to do to solve or at least lessen this? I'm running black/gold springs IIRC with variable valve setup in offroad position and 50wt oil. Would stiffer springs help?
