I'm ordering the R/c 4.5 lift kit that comes with leafs, coils, shocks, brake ext, and also quick disconn. Okay so i'm wanting to add about another inch to the front and rear to make it about 6 inchs because the R/c coil springs aren't really 4.5 they are more like 5 inchs. Anways what all will i need to give it the extra lift to the front and rear. Adj trac bar, sye, or what? Let me know what the cheapest route i can go. Not going to be flexing out at all or anything.
