You mentioned 7 clicks from stiffest for normal street driving.I've ran Tein comfort sports on my F for almost a year now. All I can say is it's definitely stiffer then stock when setted to the stiffest. It handles very well and noticably less body roll. For normal street driving I have all 4 corners at 7 clicks away from stiffest and it still handles well. Like what others think these aren't the same floaty feel Tein CS's like how it feels on the is250 and is350. I don't feel any floatyness at all with mine. Spring rates for the F's applications are 12k/10k which are alot stiffer then the is250/is350 cs's spring rates of 7k/7k. I also have the EDFC unit so I can control the settings inside the car instead of getting out and ripping out panels in the rear to set the rebound/compression which I find a hassle especially in a luxury car. What I really like about the EDFC is when I'm on a super bumpy road all it takes is 1 push of a button to go to softer setting. With the EDFC u can have 3 different memory settings. I made my 3 race/street/comfort
Can you also let me know your settings for race & comfort?
I am in the process of playing with the damping settings on my Tein comfort sport and would like some recommendation.
