Need Advices to Setup Rear Suspension

Have u tried lowering front of car. When i ran cal tracs we had front end on lower bumps and upper bumpers off.

Folks, I measured front end travel this weekend and had 4.2" of travel... So I reworked the upper suspension bumpers that was blocking my front end travel and lowered front of car 1/2" and now I've 5". I know that the golden rule is do not change more than one thing per time but I'm thinking in tight rear shocks extension from 12 to 18 to start.

Jully 22, 23 will have an event and I will can test my last adjustments...

Thanks Guys!
