K-Tuned 2012-15 Civic Base and Si replacement front control arms with hardened rubber bushing. Unlike OEM we use  a full bushing to give increased rigidity and strength.  Hardened rubber bushing is best for street cars. Spherical bushings best for high hp setups and race cars. Old worn and tired bushings will drastically reduce the feel and handling of your car. Replacing worn bushings and suspension components can really make an older car feel new again. Our rubber bushings feature a stiffer durometer than OEM and are designed to last. Spherical bushings are perfect for race cars that need solid but smooth movement of suspension components.
