I am back from another interesting day.
This time I could drive together with our ETS gang and like this see all weak spots. First of all I experimented with spring rates. I ended up with the springs from the Tamiya Tuned spring set for Touring Cars. These springs are very soft. The hardest spring equals Xray 2.3. The softest rate is approximately 6-7lb/in. These are in the rear. The medium hard yellow springs are in front. The soft springs in the rear also helped with the steering. The steering was very smooth today. It also took away the grip roll tendency. The car was easy to drive, I had not one accident. But the rear was much too stuck. During the day I reduced the rear toe in several steps from 2* to 0*. Zero toe was good, but not good enough. Next time I will also reduce camber, maybe use a anti roll bar.
