My race car weighs about 1000kg and is front engine / rear wheel drive. I use Yokohama A032R 225/60-R15s and a front spring rate of 925lb/in. I've got a head on picture of my car half way round a corner at Donnington and its clear that my loaded front tyre is significantly more "squashed" than the unloaded one. Also, if I "wobble" my car when its standing still, virtually all the movement is in the tyre walls not the suspension. Strange then that it feels completely and solidly planted on the track while I'm actually driving. There is no feeling of "wander" from the steering... and I'm comparing to when I used to drive karts! Thoughts anyone ??
