Rear shock setting from slick to track with teeth?

[Signman]

In the video the tire rises into the wheel house / the chassis lowers on to the tire changing the angle of the lower four link bar to point down further in the front adding bite which will slow wheel speed.

Stock type suspensions tend to separate the tire drops out of the wheel house / the chassis rises causing the what would be the lower bar the leaf spring or trailing arm in a coil spring to change angle to point up in the front and take bite away. Am sure there are schools of thought on this and would love to hear everyone's ideas. My method is to let the tire drop as fast as is reasonable to plant the tire then keep it planted and use air pressure to control the tire from running over itself.

To let the tire drop out of the wheel house quickly the shock should separate easily, to keep the tire planted the shock should resist compressing.

Most double adjustable shocks control separation/extension on top, compression on the bottom. Check specification included with shocks when purchased identify minimum and maximum then start halfway between the middle and full loose on top and middle and full tight on the bottom.

Working with someone like Mike Mans or Santhuff will get you in the ballpark quicker.

Guess I'm doing it all wrong. I never touch mine.

Ed: I'm with you, I never change rear shock settings because our suspension / combos have been sorted out and we normally run on quality tracks that do a good job of prep. I believe the front shocks are more important than the rears. I do adjust front rebound, tire pressure and sometimes engine timing when my small section of left brain thinks it's a good idea.

When I test at the Friday night TNTs here at home, pretty much no prep, I drop the rear tires 2 psi, and back my front Santuffs off 1/2 turn, add 1/2" front travel, and it dead hooks, same at the NHRA races. Eastexas Racecars solved all that for me.
