I'm a performance car enthusiast, and I was hoping this product would deliver on its promise for a smooth brake performance .As a result of my tests, I determined that it falls short of expectations. Although the price is affordable, the quality is subpar, with noticeable squeaking and grinding noises. The only pro is its AFFORDABILITY, but the cons outweigh the price. Overall I would not recommend this brake system to anyone looking for reliable and noise-free performance..
