This is a easy-to-bolt-on component that will dramatically improve handling capability and minimize the traction-robbing body 'lean' during cornering. This complete kit includes all necessary hardware including polyurethane bushings, TIG-welded reinforced bushing brackets and synthetic bushing grease.
I bought this for my 2017 Mazda6 and it fits perfectly and made a measurable improvement in my car's handling. It's well worth the purchase price and may honestly be the best bang-for-the-buck upgrade available for these cars. Install wasn't difficult and the quality is impeccable. Highly recommended.
