Install time/difficulty with sway bar, coilover, camber arms & brake cooling kit

[cossie1600]

I can wrench on my car, but time and space is a huge issue for me now. Out of the items i mentioned, which one would be worth doing myself and which one I should just pay to not do it?

Coilovers, sway bars, camber arms, stillen brake cooling kit

I think sway bar labor is one hour each, not sure about the rest. The brake kit might be 3 hours or so

Thanks
