Hello Roka. I am new to this forum but I have worked on my S for some years. A year ago I was sourcing a pressure plate for my S and I was able to find this new old stock pressure plate. The sachs number is on it and it fits S and S2. I had set the current Sachs K298-02 next to this and I cannot see any physical difference in appearance however I am not sure how you would test clamping force. Any other S person have an additional comment?
