The only thing you truly gain is header clearance with those kits and maybe more brake selection since its all Mustang II based. Lots of guys auto cross, drag race and drive hard on the street with the stock suspension. I guess the other bonus is the K frame can come set up for the Gen III Hemi but there are mounts for the stock K too. It all cost money and some times its worth the price but is it worth it for you?
