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 think its common with carbon/kevlar pads. Its hard to get them hot enough in a street application. They grip pretty well cold but still aren't at their best.
I just installed some KFP Magnum street pads in my white car and they started squealing almost right away. I'm hoping that once I properly bed them in they won't be quite so noisy. The race pads I took out were awesome in terms of performance but almost always made noise as soon as the car was below 30mph. |
