Rear sway bar on a first gen

[CSG]

For me I find that bars almost always make the car "feel" faster and more controllable unless you really go too big. My lap times did not align with the feeling though. Too much rear bar (rear wheel rate actually) will cause oversteer as it takes grip away from that end. When I was less experienced I would put cheap Nitto 555 tires on the car for testing. You can really see how the car is balanced that way and learn a lot about how things effect the handling when the tires give out before your talent does. Not saying you are inexperienced as I have no idea your driving level.
