When it comes to sway bars/anti-roll bars, you can change them as long as they are available at Tire Rack and bolt to all the stock places and run the stock route through the car.

If there is a sway bar/anti-roll bar you really want that isn't available at Tire Rack, and it meets the intent of the rules of design and availability, you can check our "Alternate Approved Anti-Roll/Sway Bar" list, or use the "contact us" page to request a bar get approved.
