transbrake with caltracs, help

I had a similiar problem with my Dart. What was happening was the shocks were reaching full extension when the front end was in the air. I also use Cal Tracs and Rancho 9000. I firmed the rear shocks all the way to determine that was the problem. I then backed (softened) the shock off until it launched right. Most tracks, I have them set on 6 or 7. Hope this helps
