Today I used my club duty to test my changes. The setup really sucked for the first three runs. Then the rubber tires died tire for tire, making it hard for me to judge my changes. Slow speed understeer combined with high speed oversteer ruined my fun for most of the day. Because of the lay down shocks the springs appear much softer than usual, causing the chassis to move a lot under load and making it twitchy to setup the ride height. The car was especially bad in the entry and the middle of the corner. I leaned against this behavior with thicker oil in the rear geardiff and spotted a wrong caster setup. With that setup I drove my last battery of the day.
The car was suddenly dialed in like never before. And if I mean dialed in... I mean it! The steering is faster than my eye movement
Entry, middle and exit are beautiful fast; the rear follows in fast corners and steers in the slow ones. I am sure I beat my TC6.1WC lap time today, but didn't verify it as I didn't expect such a transformation...
Next week I am going to order AE's touring car spring set. There I will find much harder springs to cure the chassis movement
