Weight Distribution
Weight distribution is the amount of weight (car and driver) being carried by the tires and is given as a ratio, such as 60/40. The ratio can be for the weight carried by the front compared with rear tires or one side of the car compared with the other side. (For example, the front and rear weight distribution of a GTV/6 is almost 50/50, which means that 50 percent of the weight is carried on the front tires and 50 percent is carried on the rear tires.) A car maintains its highest traction when all the tires are working equally.

Aerodynamic Devices
Aerodynamic devices channel air flow around and over a car body creating areas of high or low pressure, which will load or unload the tires as required. A nose spoiler keeps the front of a car from lifting at speed by blocking some of the air flow beneath the car, increasing traction at the front. A rear spoiler increases downforce at the rear of a car, increasing traction at the rear.

Adjustable Shocks
Shock absorbers dampen the ocillation of a spring. Adjustable shocks can be used to balance under/over steer; stiffen front shocks for less oversteer, stiffen rear for more oversteer and visa-versa. Be careful not to over-stiffen the shocks as the car will bounce over road irregularities losing traction as the wheels leave the road.
