WEDGEIn NHRA this is an engine with a combustion chamber resembling a wedge in shape. In NASCAR it refers to the relationship from corner-to-corner of the weight of the race vehicle. Increasing the weight, adjustments made by turning "weight jacking screws" mounted on each corner with a ratchet, on any corner of the vehicle affects the weight of the other three corners in direct proportion. A typical adjustment for a "loose" car would be to increase the weight of the left rear corner of the vehicle, which decreases the weight of the left front and right rear corners and increases the weight of the right front. A typical adjustment for a "tight" vehicle would be to increase the weight of the right rear corner, which decreases the weight of the right front and left rear and increases the weight of the left front.
WEIGHT TRANSFERCritical to traction, vehicles are set up to provide a desired weight transfer to the rear wheels. Upon acceleration, the front wheels lift and the weight shifts to the rear wheels, which makes them less likely to spin.
