[Track types] SHORT TRACK Martinsville (Va.) Loudon (N.H.) Phoenix Richmond [Wedge] Loose Corners are so tight on short tracks already that cars are set up loosely so they can turn more freely. [Track bar] High The track bar is set very high, nearly as high as at superspeedways, to help the back end swing around in the corners. [Nose weight] Back Nose weight is usually toward the back, the second-loosest setup after superspeedways. [Brakes] Heaviest brakes / slightly front Short tracks require the biggest, toughest brakes, because drivers use them hard in every turn. Teams also add fans in the brake duct hoses to cool the brakes. Bias is set to just slightly favor the front brakes. [Camber] Highest angle Front wheels will be cambered more than for any other type of track because tires work hardest going around the tight corners and need all the help they can get. Speeds are not high, so tire wear is minimal. [Springs] Very soft Teams can use very soft springs on flatter short tracks because speeds are slow. [Shock absorbers] 
Stiff front / neutral rear Short track shocks are very stiff in front, so that if the driver slams on the brakes, the nose doesn't hit the track. Rear shocks are neutral, because the back needs grip to accelerate after a slow turn.
