I'm considering upgrading the suspension on my 2004 Comp G in the near future. I've been reading a lot of forum posts on suspension upgrades, but everybody seems to recommend something different and most threads are for 97-03 GPs, which I know have a softer suspension than a Comp G. So some upgrades for earlier GPs may not be as much of an upgrade for my car.

Mainly what I want is more stability in longer, high-speed turns, as it feels like my car gets a little antsy in those situations. It doesn't feel coordinated, almost like the car wants to wander a bit, and it feels like hitting a small bump would be enough to break traction and start sliding. The car has been aligned in the last year and has quality tires. It just doesn't inspire confidence. I just want a few parts, not a complete overhaul, but something that is a noticeable upgrade in the $300 to $500 range. My car currently has about 169k miles and most if not all of the suspension is original. What would you guys recommend?
