There's some debate on whether to replace the front sway bar on a 1G AWD. Some say the front is already large enough, and a bigger bar upsets the balance of the car. As for the rear sway bar, you have your choice of RM Racing or Suspension Techniques. I'm partial to the RM's but I have a 2G.
As for springs, you have to make this choice - how much ride quality are you willing to sacrifice? If you live in an area with rough roads, Ground Controls, even with Koni's, will jar you to death.
I have Koni's and Ground Controls (see my sig) and the roads are pretty good here (NC) and it's still stiff. The Eclipse is my fun car, so I don't have to drive it every day. I'm willing to sacrifice the ride for a good auto-x machine.
