I have had the SC&C front suspension setup on my '68 GTO for almost 3 years now, and I really like the handling. That being said, I am running stock springs as the springs SC&C shipped dropped my car into the weeds...it looked bad, rubbed, etc. But, with the SPC upper control arms, stock lower control arms with new rubber bushings, Howe tall ball joints (upper and lower), Hellwig swaybar, and Bear brakes that clear my 15" wheels (all sourced from SC&C) this is by far the best handling and driving muscle car I've owned or ridden in. Many of my muscle car buddies have said the same after going for "spirited" ride in my GTO.
For the rear setup I have stock springs with the GM style boxed lower control arms and sway bar, GM style braces, and CPP adjustable upper control arms, with stock rear drum brakes. This is cheaper than most aftermarket kits I've seen and really tightens up the rear suspension.
Another way I saved quite a few bucks is by using Monroe shocks from my local auto parts store instead of the high buck shocks and/or coil overs that most of the suspension guys push. Works great for me, although I am considering trying some coilovers in the future due to simpler assembly/disassembly and adjustablility.
For steering I am using a NEW (not reman) CPP steering box and high performance PS pump. This made a HUGE difference in the steering response and tracking of the car.
Summary...love the SC&C stuff but think about how you will be using your car, and how you want it to look (ride height), before you jump into the full kit or you may end up with more than you wanted/needed.
