Quote: 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.
That is correct. I do have some downforce and drag numbers from the Chrysler wind tunnel of 1970. It loks like the engineers where much more focused on optimizing drag than tuning in more downforce back then.
