k even if you wernt thinking of going with me i would say performance... just imagine the lift and bigger tires with stock performance.... dude thats gonna blow.... plus you would want a trans gauge because the bigger tires will put more stress on your trans esp with stock gearing which will raise your trans temperature.....
so +1 for performance no matter who you go with... oh and just FYI i can get you a 5" budget kit as well

P.S with that large of a tire i would def suggest regearing so you have to take that into account as well... also that procomp kit doesnt come with longer brake lines so i would upgrade to longer SS braided lines and to help stop that beast even more i would do powerslot cryo rotors up front... oh and did i mention your gonna have to have your front driveshaft lengthened?
