Lateral-g Forums - 2nd gen F-Body suspension

Wow - you have tons of options. These are just a few of my views on them. All will be very capable on the road and the course.

Air Ride - Street Challenge setup

-very adjustable
-coolness factor of the park it and slam it option
uses the stock front subframe with a taller spindle for better geometry (camber gain).

DSE Quadralink and Subframe

http://detroitspeed.com/productpages/product_page.htm

-very well engineered
-detailed installation instructions (DVD video if you want)
-can fit big meats up front and in the rear w/ the mini-tub

AME Subframe - I think they are working on the rear setup.

very comparable to the DSE front - this one is mandrel bent tubing vs. the DSE hydroformed rail. It's more of a fabbed look vs. an OEM look. AME uses C5/C6 upper/lower control arms as well as upright. DSE utilizes their own control arms with the C5/C6 upright.

Lateral Dynamics - 3 link rear w/ watts link.

From a design standpoint the 3 link is superior. Many discussion have been had on this forum and others comparing this setup to others - mainly the Quadra-link. I haven't been exposed to too many people with this setup. It isn't being widely used yet to my knowledge, partially due to its "newness"

SC&C front setup w/ ATS spindle (stock subframe)

I really like the ATS spindle setup from the standpoint that you get the opportunity to utilize C5/C6 bearings and brake components and avoid the cost of an entirely new subframe. I've heard good things about Marcus and his support.

I'm sure there are other options out there. DSE also offers their upper and lower control arms and an upgraded steering box etc. for the stock subframe.

In the end, I guess as always it comes down to budget and intended purpose.

Back to your original question - "Best" is pretty vague, as they all have their advantages and disadvantages.

If I owned a 2nd gen car today and my budget permitted, I would give it the full DSE treatment. - personal preference

I know people that have had personal experiences with all of these companies with the exception of Lateral Dynamics (not necessarily good or bad, just haven't had any experience with them) The other companies are all stand-up operations with good support and products.

Hopefully my ramblings have helped in some way. The good news is that you have a ton of choices - the bad news is you have to choose.:) Do plenty of research and use the "Search" function on here liberally to educate yourself as much as possible. Any way you look at it you are going to spend some coin.
