• ARS suspension system includes ARS arms, graphite 0° C-hubs for optimal flex faculties, hard suspension block, ARS suspension block, and ARS linkage linking the holder to the suspension block
• ARS linkage angle – adjusted by adding/removing shims regarding the steering block and ARS-holder changes the toe-in characteristics associated with the back tires during chassis roll
• Aluminum suspension system holders featuring built-in Suspension Settings (ISS) for fast & simple suspension system geometry adjustment
• Suspension holders allow stronger mounting of suspension system hands, therefore the suspension geometry of the car does not change even with difficult crashes
• Suspension mounting system permits extremely free supply movement, which provides higher traction, smoother driving, and enhanced steering
• Suspension owner system allows suspension system arms become mounted separately from bulkheads making it possible for elongated chassis flex to come up with more traction
• Independent suspension system holders enable more precise and fine set-up alterations via various bushings
• Rear suspension aluminum holders feature integrated toe-in
• C-hubs available optionally in standard caster perspectives (0°, 2°, 4°, 6°); obtainable in four hardnesses (M - medium, H - difficult, G - graphite and aluminum)
• Hard front steering blocks increase steering response, decrease front tire overheating in high-traction conditions
• Small, robust steering blocks made from unique proprietary composite product, available optionally in 3 hardnesses (M - medium, H - difficult, G - graphite and aluminum), and have 2 Ackermann positions
• Rear uprights give increased stability; available optionally in 3 hardnesses (M - medium, H - difficult, G - graphite)
• back uprights function integrated 0° toe-in to prevent suspension geometry alterations in severe crashes
• Arms function revolutionary SFATM (Suspension system Flex modification), revolutionary and unique graphite stiffeners allow for super-quick suspension system flex adjustment to easily adjust the traction associated with car under different track conditions
• Suspension hands function incorporated anti-roll club mounts; rear arms function 3 different anti-roll club mounts for super-fine adjustment of this back anti-roll bar
• Suspension hands made from graphite material for improved traction and stability of car
• Anti-roll club system is mounted to the bulkheads via bearings for extra-smooth motion and maximum precision, and part play is eliminated by aluminum bushings
• Anti-roll bar height is adjustable via simple screw adjustment… fast & easy
• Front 1.4 mm & rear 1.3mm anti-roll bar cables included
• Easily-adjustable wheel offset making use of optional wheel hubs  (-0.75mm, +0.75mm, +1.5mm)

Drivetrain

• Lightweight center layshaft CNC-machined from aircraft aluminum
• 84T 48P spur gear  - extra-hard product, wobble-free design
• 38/20T (1.9) internal gearing for efficient, superior drivetrain
• Premium-quality drive belts
• C-hubs with big spaces for quick & simple assembly/disassembly of the CVDs and ECS drive shafts; stops collision of CVD or ECS drive shafts with C-hub in serious crashes
• Super-light drive axles
• Front Extra-Strong ECS drive shafts equalize the speed involving the drive shaft and wheel. With a unique 2-piece joint involving the axle together with wheel, any extreme wheel turning angle is divided in to two shallower angles without joint binding. Which means whatever the cornering rate and wheel angle, the inner wheel will not bind or vibrate. Drive through corners is more stable, more accurate, and easier to drive
• ECS drive shafts produced from world-renowned, self-developed HUDY Spring Steel; hand ground for optimum precision
