lift throttle oversteer

One of the advantages to having bellcrank actuated springs is that the system can be tweaked to provide a nearly linear, rising or falling rate. I always plot the curves for both front and rear and make sure that the front has a steeper rising curve than the rear. In order to address drop throttle oversteer, you can effectively have rising rate front springs via rocker geometry. With a rising rate on the front, when the front dives due to throttle lift or braking, the front tires see a higher rate spring. This higher rate can be enough to alter the handling balance and cure drop throttle oversteer. I have designed for this on all bellcrank suspensions, and it works!
