wedge

What is wedge in a dirt oval RC car, and how can I use it to improve my car's handling?

Wedge or cross-weight refers to the amount of weight that is on the right-front (RF) and left-rear (LR) tires as compared to the left-front (LF) and the right-rear (RR). It is usually calculated as the weight measured on the RF and LR tires relative to the total weight as a percentage.

Formula for wedge: RF weightLR weight / total weight
