The Bapmic speed sensor didn't align with my car's computer, resulting in an automotive catastrophe. According to my experience, this is one of the worst brake system parts I've purchased. The only pro is that it was easy to install. The cons include the fact that it failed to perform its job, caused me to lose control of the car and resulted in a hefty repair bill. I wouldn't recommend this product to anyone looking for reliable performance car parts and accessories.
