I have to wonder if those rates are predicated on have a lot of down force at speed. I have vague recollections that on the winged cars running back then down force was a substantial factor and the spring rates took that into account.
In 1971 stock cars, wasn't track banking a much larger factor then aero on spring rates? I never thought they achieved HIGH downforce, just a huge improvement over the huge lift demons from previous years, speaking in 1971 terms. 
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
