So, after careful consideration and research, I've decided I want to upgrade the sway bar. I can't help but notice the understeer of the car and feel that if it leaned less and understeered less it would be darn near perfect for what it is. So, question, should I go for the STI 19mm sway bar or the Perrin 22mm? I only ask as I'm not sure how dramatic a difference the 19mm will make over the Perrin 22. Also, has anyone put a larger sway bar on the front, and would there be any good reason to?
