Not sure if I want to lower my guy. Is there something I can put on his rear end to stiffen him up? *looks innocent*

To what are you responding? The float issue? A stiffer suspension will do very little... The goal is to reduce the volume of air moving under the vehicle, remove turbulence and limit the amount of air pushing against and trying to get under the tires. Air dams and a low lip will help more than stiffer suspension, but clearance remains just as much of an issue.

He just seems a bit soft in hard turns. Of course a continuing problem is the car seems to be "flexing" in hard turns and with the top off it becomes a downright problem.

Anyhow, where can I get air dams for under my car? The previous owner destroyed the ones that came with the car.

The MKIII never came with air dams. If you're asking about the front undercovers your only options are the dealership or used. Air dams you'd have to fabricate, there's not a lot to them and you can look at many modern vehicles to see how they're employed and to get an idea of placement. They're just rigid plastic sheets which extend down below the car to divert air from going under the car and away from the tires. Even Prius have them.

EDIT: Air dams for tires look like small (usually hidden) reversed mud flaps for the front wheels.

For turning performance a much stronger anti-sway bar will make a very big difference without sacrificing ride quality in a straight line. It does nothing for stabilization at high speeds though... different problem, different solution. Naturally, stiffer suspension will help too but the ride will get a bit rougher.

Note that '89+ use plastic end links. When using a significantly tighter anti-sway bar they may break.
