Need some suspension advice

[blazincopper]

Ok I am about to start restoring my 67 Camaro for a 3rd time. I am going to make a daily driver out of it, but I want that pro touring stance and I want it to handle good. As far as engine, I am probably going to install a mostly stock 5.3 setup. Any advice will be appreciated.
I want to know what is the biggest bang for your buck on suspension. What is worth the money and what is not.
Which is better - air ride or adjustable coil overs?
What is a good "bolt on" rear suspension?
Are tubular a arms worth the money?
Does replacing the entire front subframe help that much or is it just as good with tubular a arms and coil overs/air ride?
I want a deep dish on the rear wheel, but I do not want to do a minitub, any thoughts on using a narrow rear end so I can reduce back spacing and so I can have deep rear wheel?
I know that the S10 rearends are about 6 inches narrower than the Camaro rearend and they come in several different gear ratios. Has anyone ever use this setup or what would be the pros and cons?

Thanks again for any advice
