I've used this copper tubing in my car's steering system and it's simply amazing. The quality is top-notch and it has made my car's handling smoother than ever before. When I tried this product, I could feel the difference in my car's steering right away. It's easy to install and has lasted me longer than any other tubing I've tried. The only downside is that it's a bit more expensive than other options, but the quality justifies the cost.
