I'm running the Porterfield R4S street pads front and rear (Boxster calipers and rotors up front, with widened 914 rear calipers and 20 mm vented and cross-drilled rotors), and they squeal like a Banshee! I'm running the anti-squeal shims and we've tried the Wurth anti-squeal treatment, but to no avail. Is there any tried and true cure for this malady or is this just par for the course with carbon-kevlar pads? |

I use the same porterfields and get small squeel when very slow stopping only, when they heat up you can feel the grip really improve.. when you need them to really work hard they are there for you. |
