Anyone here had experience with the Porterfield RS4s?
FWIW, rotor judder is generally from uneven hot pad transfer to the rotors. This is usually caused by failing to take a nice easy cool down lap or an easy drive down paddock row to cool the rotors down before stopping the car. I had this problem with Pagid Yellows and it got really bad but in hindsight, it was probably my cool down habits, not the pads fault. I cool down for at least 2 miles now and have never had another problem.

The best high heat pads I have used are Raybestos ST-43 custom cut from Porterfield. Excellent modulation, heat management, and they last 20+ track days. I have run these pads for about 7 years now and love them. Downside: They squeal like a school bus when cold.
