As a result of using this product I found THAT my car's ride quality drastically improved. The Prothane bushings provide much better support than the factory rubber ones. My car's handling feels more precise, and there's less body roll in corners .The added benefit is the durability of the product, which will probably last much longer than the factory ones. The only con is the installation can be a bit time-consuming, but the results are well worth it. Overall, it's an excellent investment for any Automotive enthusiast looking to upgrade their Struts & Suspension..
