These brake pads failed to deliver the performance I expected from a semi-metallic series... Thanks to my knowledge gained in practice in the automotive industry, I can confidently say that these pads have a very short lifespan and are not suitable for performance cars. The only positive aspect is their affordable price. The major downside is that they don't provide enough stopping power and will need to be replaced too soon which makes them a waste of money..
Pros
High-quality semi-metallic composition for increased stopping power and durability.
Cons
Can produce more brake dust than comparable ceramic brake pads.
Rear brake pads on a 2007 Altima. Installs in about 15 minutes. It took about a mile of driving and stopping to get seated and get rid of the initial FHA noise. Really helped reduce stopping distances. Time will tell if this reduces the amount of brake dust my last kit produced.
