If you have your car working properly from turn entry through the center, you often will have few problems on turn exit that a gentle right foot can't handle. However, over the past years we have stressed maintaining a correct front end geometry layout, including the bumpsteer, Ackermann, and roll center characteristics regardless of whether or not you have a stock front clip or a tube frame car. You probably are like Loomis and unable to use fancy adjustable shocks, but they can still be a valuable tuning tool-even if you have to spend the loot for two sets. The LF tire will be doing less work with these changes but should still be touching the ground, and the Ackermann will help it provide turning power. fZ(L4&e,80F `uR Y/71xhEfH U(faXA`Z'(. 0000026778 00000 n Here is a list of phases of grip that a dirt team might encounter on a typical race day, along with the associated estimated g-forces that the car might experience: 1. was brp1537.
