I am looking at going from the staggered factory tires to 18" square setup using 315/30 hoosiers on 11x18 rims all around. I currently have P springs installed along MM C/C plates, adj. UCA, LCA's and panhard bar. From what I understand, I will need to change up the factory swaybars. The question I have is should I change the front, the rear or both? Any brand better than the other? Or, being that I am using P-springs and factory shocks/struts, are the hoosiers going to be to much for that spring/shock setup?
