Weight and Downforce - Theory Friction supplies the resistance to sliding that we use everyday. Without friction we couldn’t walk or crawl and nails wouldn’t hold. Consider a block of some material, a cube about an inch on a side. The block is lying on a surface, say a table. The block has some weight because of gravity. We’ll call that weight Fv, the vertical force, because it acts straight down. If you push on the block with a force (F) parallel to the table, you can make it slide on the surface. If you push hard, it will slide right off the table. If you push against it very lightly, it won’t move. :: Click for detailed Weight and Downforce - Theory information Wheel Toe Wheel Toe (see Figure 3-6), is the turning in (or out) of the wheels when viewed from the overhead position. The actual amount of toe is normally only a few minutes of a degree. The purpose of a static toe specification is to ensure parallel rolling of the wheels, once the vehicle is in a dynamic state. :: Click for detailed Wheel Toe information WSP Wheel Slip Protection – System initially incorporated in Aston Martin range of cars, as far as automotive industry. WSP mode operates the clutch and gearbox, auto-shifting at 3200 rpm in low-grip conditions to prevent sliding. Works similarly to Traction Control.
