[QUOTE="Mark Newhan, post: 781590, member: 4329"] I believe that it is important to use all of the enginneering pricipals available when designing a front end. The purpose of KPI is to have the center of the scrub radius in the center of the tire. If you stray to far from this you load the steering components and ultimately the steering wheel when you get feedback. The further negitive offset (or outward spacing) the more leverage on the steering components. So the conventional wisdom has been "make the steering more powerful", which does not cure the issue. The enginneered parts that you purchase from Pro-Am are designed with the wheel and tire application used in off road racing. A four wheel drive vehicle is very pron to showing an operator of a vehicle the illeffect of improper KPI. Anyone that has driven a Rhino with either wheel spacers or negitive offset wheels can attest to the dramatic effect of "torque steer". It is the same feeling you get with a front wheel drive car when you turn the wheels and stand on the gas. This is the exact opposite of what a two wheel drive feels with the improper wheel offset, which destroys the effects of proper KPI. It is a slow hammering of the steering, which will put an off road race vehicle out of a race. [/QUOTE]
