I started out with a 2.5" budget boost with no adj front trackbar and had no issues. Over time I have changed to 3" coils and after 2 years I am just now getting around to adding an adj trackbar. I would say if you are planning on wheeling and pushing your articulation I would focus more on the bump stops or limit straps if needed. It's really trial and error until you get out and see and hear if you are rubbing. I have added suspension parts over time and nothing has ever been a problem so pick a pace to start at and go for it.

 

Ok i think I'm beginning to understand now. thank you everyone for your help.
