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
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.
Ball Bearing Actuators
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.
Large Bearing Spindles
Front spindles and rear hubs have been revised to accept a larger 8
× 16 × 5 outer bearing for increased durability.
Revised Chassis Side
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.
Adjustable Caster Blocks
The adjustable, 15-degree caster blocks make it possible to tune dog
bone plunge by changing the height of the spindle.
New Bleeder Shock Caps
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.
Driveshaft and Dog Bone
Molded rubber boots on the universals and center drivetrain dog bones
increase U-joint life by holding lubrication in and keeping dirt out.
Redesigned Shock Towers
The machined aluminum shock towers have new camber link and shock
location holes that give racers more tuning options for changing track
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.
