I've tracked this car on stock springs, 4.5kish front springs and 6k front springs. The higher the front spring rate, the more stable and level the car was under braking, no comparison. With factory suspension and 245 RE71Rs I was practically sawing at the wheel to keep it in a straight line.
Continuing your logic, competition cars running ultra high spring rates (3-5 hz) and slicks would stick their butts three feet in the air under braking. I can't say I've ever seen that, personally.
