The story of the 8IGHT platform is the story of a champion – one that encompasses multiple ROAR national titles in addition to major wins on the international stage. The 8IGHT 4.0 buggy builds on this championship-winning heritage with updates to the suspension geometry and drivetrain layout that make it both easier to drive and tougher to beat.
New suspension geometry makes it easier for drivers of all experience levels to turn faster lap times with fewer mistakes, particularly during brutal, hour-long mains.
The engine has been repositioned to reduce front driveshaft angle so more power makes it to the front wheels.
The revised throttle actuator now uses bearings to further improve throttle and brake response. It also features a new brace that prevents flexing during heavy braking.
Front spindles and rear hubs have been revised to accept a larger 8 × 16 × 5 outer bearing for increased durability.
The chassis side guards have been updated for a better fit. They also feature indentations for the Velcro body strips.
In addition to its new position, the engine mount has been designed with a larger footprint that substantially reduces chassis flex and fatigue underneath the engine when racing on high-grip tracks.
The adjustable, 15-degree caster blocks make it possible to tune dog bone plunge by changing the height of the spindle.
The new bleeder shock caps and internal seals allow for easier rebuilds while using an emulsion shock setup. New bushings that press into the shock cap further improve durability.
Molded rubber boots on the universals and center drivetrain dog bones increase U-joint life by holding lubrication in and keeping dirt out.
The machined aluminum shock towers have new camber link and shock location holes that give racers more tuning options for changing track conditions.
The chassis has been designed to accommodate hard-mount ballast weights so it is easier to meet the ROAR minimum weight requirement.
The cab-forward body moves aerodynamic pressure further forward on the car, which improves steering.
