ImLimited

Hey there. Just purchased a 2017 Limited. I have the Roush Performance Pac Level 2 already on the way. But I am confused AF about upgrading my suspension to add street performance over offroad performance. The only thing I will load the bed with is my sportbike on track days, no other heavy towing or loading. I want to upgrade my suspension for handling and speed on the pavement, as opposed to offroad. Can anyone advise me on some suspension upgrades without having to completely slam the truck? I'd rather spend extra money and really enhance the truck then save money and **** up the ride. Thank you very much for any assistance.
