hey guys i am wondering what suspension i should go with. thing is id like to have some lift either a 2" leveling kit - 4" suspension kit. i was about to lift the truck 6 inches but after i heard my performance would be dead i decided not to go with it. what if i used air bags? 0" on the dragstrip and max level on street (4"? or 6" ) i have 35's on my truck already that is the tires size i want. My main thing is i need speed in this truck and i also need good looks. what is your advice?
