The Superpro rear sway bar kit for the 2015 Audi A3 Quattro Premium is a 22mm adjustable bar with HD end links that reduces body roll and sharpens cornering. Multi-position adjustability lets you raise roll rates roughly 30–50% over OE by changing end-link position, so you can quickly tune chassis balance with common hand tools. The extended TRC4300 links reach adjustment points more easily and give a firmer connection than OEM links.
