I've driven the following setups:
OEM - extensively. Excellent street/track setup. Rarely on track do I feel like the suspension is "holding me back". I run a square wheel/tire setup so complaints about undeersteer... I don't share those.
OEM with Eibach springs - drove on street only, I was surprised at how comfy they were on Comfort mode. They lower the car more in front than rear, but I've heard changing the rake that way benefits the handling on track. Nice upgrade.
OEM with Eibach springs and swaybars - only drove on street, but handling was just as predictable as OEM, the one twisty section I got to do, the rear end slid out on throttle very progressively. I would not hesitate to run or recommend this setup for someone looking for an upgrade with no downside to comfort. Eibach knows suspensions.
OEM shocks with KW Sleeve kit and Stillen swaybars - drove on street only, handled really well, comfort about the same as OEM. I would definitely recommend the Gotboost endlinks with the Stillen swaybars. For height adjustability, modest upgrade, this is a good way to go.
