Review on Rear R1 Concepts Semi-Metallic Series Brake Pads 2311-0905-00 by David Martin

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..
