Perhaps it would be a cool feature to have a different topic or concept explained weekly (or monthly) in this section. We could begin to utilize the vast knowledge and resources of many of our membership to the unwashed masses such as myself.
I propose the first topic: scrub radius. The textbook definition is: "The distance between the extended centerline of the steering axis and the centerline of the tire where the tread contacts the road. If the steering centerline is inboard of the tire centerline, the scrub radius is positive. If the steering centerline is outboard of the tire centerline, the scrub radius is negative. Rear-wheel drive cars and trucks generally have a positive scrub radius while FWD cars usually have zero or a negative scrub radius because they have a higher SAI angle. Using wheels with different offset than stock can alter the scrub radius."
Now what the hell does that mean???
