Slope Shooter

Because these cars don't have up-stop wheels that lock the cars onto the track, Slope Shooter is classified as a "Side Friction" coaster.  The first roller coasters were all side-friction coasters, but since up-stop wheels were invented over 100 years ago, nearly every coaster built since then has road wheels, side wheels, and up-stop wheels.  By using up-stop wheels to lock a coaster to the track, more aggressive maneuvers and steeper drops are possible without worry that the cars will lift off of the track.
