Epic thrills are right on track with the Custom Curve Kicker accelerator - part of the Hot Wheels Track Builder System! The Custom Curve Kicker accelerates cars around turns and adjusts the turn angle so kids can kick their vehicle around the track at any angle from zero to 180-degrees! The adjustable feature lets kids create a crazy amount of angles! Kids will love testing their skills and timing while racing their Hot Wheels cars. The Custom Curve Kicker also includes connectors, track pieces and one Hot Wheels vehicle. The possibilities are endless with open system play! Enhance builds with household items like red cups, paper tubes or add-ons like bricks.
