Strong, lightweight, solid aluminum, one-piece cars boast stainless steel-wire ball guides that keep the high-strength Torlon balls captive when the car is off the track. Or flex the guides to pop out the balls and snap them back without removing the guide. Sculpted car bodies reduce weight. Low-profile Micro CB track is fully-saturated Hardkote-anodized for toughness and scratch-resistance. Low-profile, line-shedding endstop absorbs sudden shock loads that can occur during unintentional jibes.
