[Track types] ROUGH INTERMEDIATE Atlanta Chicagoland (Joliet, Ill.) Fontana (Calif.) Homestead-Miami Kansas Michigan Texas [Wedge] Tight Wedge is set relatively tight. [Track bar] Low The track bar is set low at this kind of track to make the car tight enough for high speeds (205 mph entering corners). [Nose weight] Front All blocks are toward the front. [Brakes] Light brakes / front Teams use relatively light brakes. Drivers have to slow down more later in fuel runs because tires have less grip. For all intermediate tracks, the front brakes have more force. [Camber] Straight On fast but rough tracks like this, very little camber is used. [Springs] Front stiff / left rear soft On a rough but fast surface, teams use soft springs in the left rear to give the car more grip. Front springs are stiffer to keep the splitter off the track. [Shock absorbers] 
Balanced Shocks on tracks of this type are balanced; they need to be stiff enough to keep the car at the right attitude for aerodynamics but soft enough to absorb bumps.
