Bigger Sway Bars and Traction Arms Worth It?

Hybrids

Mainly a weekend fun car not a daily. I don't plan to ever track the car yet would like to hit the mountain roads, etc type roads eventually once I get the car setup how I want it. I have been looking around and have seen people say these cars need better sway bars anyways if you plan to do any type of driving, even just around town... Would a front sway bar be of any help? I would do the rear but don't care to pull exhaust off yet.
