Rear suspension upgrades

[69greyghost]

Guys have some upgrades that I have done to my suspension and was curious if just getting better rear shocks would help me. So far I have tubular upper and lower control arms, qa1 double adjustables, hotchkis big front sway bar and sub frame connectors, and I put kyb shocks in the rear. Am I good or should I go bilsteins in the rear and get a sway bar, go four link and coilovers, let me know what you guys think. My buddy said get bilsteins in the rear and be done with it but I am seeking info to help me make my decision. This car is a mild street car, wanna be pro touring, ls1 powered with a t56, 69 camaro Any suggestions?
