Ok, I have flowmaster exhaust, hooker lt headers with hooker offroad pipe, 4.10 rear and need some help. I am looking to do one more "performance mod" as well as something for suspension. I do not want to spend more than like 800$ total on both. What should i do? I have a lot of problem with tire spin and do not want to get slicks thats what made me decide on one perf and one suspension. Help plz!
