jcal87,
Check out the "One Lap Camaro" project. He stuck with the stock subframe and modified it to coilovers with some Chicane brackets from ATS.

I am going the same route and it should be more than enough for me. I am also adding a Lee power steering box, Global West upper and lower arms plus ATS tall spindles.
