Was at CMP last weekend. Coming off Pirellis going to Dunlop, 211 US front/ 209 UK rear. Had huge issues with setup for the Dunlops. Was hoping someone here was on the same tires and could tell me their settings for suspension and geometry. What I ended up with after a day was 4.5 turns of preload on the Penske with a 450lb spring (i am 150 without gear), shortened it all the way although I honestly dont know the total length. Forks pulled up 10mm, 4 turns on racetech emulators, 15 weight oil, .85 springs. I have a 500lb spring that I was planning on putting on for the next time out. Preload in the shock made the most improvement so I am assuming the stiffer tires are sending too much energy into the suspension with the softer settings for the Pirellis. My biggest problem was the front end sawing under acceleration. The rear felt the same until we lowered and added more preload, still a little there but improved.
