Gary, I think you should get a front and rear set that are designed to work together. The deletion of the factory rear sway bar will make the PT much more prone to understeer than it was when the factory bar was standard. If you install an overly aggressive rear bar you can easily induce oversteer, which can make the car a handful to control under certain circumstances. For the average driver understeer is a much "safer" condition than oversteer, which is why car companies tend to build it into their cars.
For the record, understeer is the condition where the car wants to push, or continue in a relatively straight line when you turn the wheel. Oversteer is when the rear end wants to step out. With a powerful rear wheel drive car you can induce oversteer by hitting the gas in a corner (Porsche 911 is the classic example); with a front wheel drive car you can often induce oversteer by suddenly lifting OFF the throttle in a tight corner, especially when you've entered that corner too quickly. While an overly aggressive rear bar won't quite make you feel like you're driving a rear drive car on ice, it will move you in that direction.
Of course corner radius, road camber, entry speed, throttle input, etc will all play a factor in whether, and how much, your car oversteers or understeers through any given corner. And yes, the same car can be made to do either in successive corners. Watch a Formula 1 race, listen to the commentators, and you'll get an idea.
