I tried Porterfield brake pads some years back. They did produce somewhat less brake dust than Textar or MB genuine brake pads, but required significantly more brake pedal force so I switched back to Textar brake pads and Kleen Wheels after a few months.

While this is an older post from another website, the findings might be interesting. http://www.benzworld.org/forums/r170-slk-class/94308-oem-versus-porterfield-brake-pads-some.html

That has not been my experience. I have found that the Porterfield's provide the best stopping power I've found while providing much less dust on my wheels. In addition, I got all of this without greater pedal pressure. R4-S pads in conjunction with ATE Premium one slotted rotors work perfectly for me.

With slotted rotors you've essentially redesigned the brake system. I'll defer to the MB automotive engineers.

I'd probably just go with some bigger later brakes if I was redesigning..

Just update from the factory parts bin of course you cannot run the factory whimpy 15 inch tires with bigger brakes. I got a used set of R129 wheels(500E) which are 16's and work well.

Slotted rotors release gases built up during the braking process helping to shorten the distance it takes to stop. Even MB engineering can be improved upon by others over a 16, or so, year period. In any event, I prefer to shorten my braking distances and the Porterfield/ATE combination fits the bill for me.
