I have bullitt springs/shocks/struts but still have the factory sway bars (energy suspension links and bushings though). I am happy with it.
The rest of my suspension is budget performance as well with 03 cobra front A-arms, 99-04 v6/GT twin piston calipers, UPR (I know but for $199 what can I do) rear upper and lower solid control arms. I also have trq box reinforcements and full length weld on sub frame connectors.
Its not earth shattering but for a car built going on 19 years ago its solid.
