Your cars scrub radiusis the distance from the steering axis to tread centerline at ground level.If the steering axis intersects the center of your tread, that would be Zero Scrub Radius. The tire would literally PIVOT in the center of the tread as the car is steered, providing more grip when turning.Most production cars have 3-6 scrub radius & this causes the tirecontact patch to scrub as the car is steered. This is literally rippingthe tread around the steering axis further inboard, versus simplypivoting at the center of the tread. This dramatically reduces the tires grip on tight corners. All RSRT front suspensions are low, or zero, scrub radiusfor more grip on tight corners!171'
