• ARS suspension is composed of ARS hands, graphite 0° C-hubs for optimal flex characteristics, hard suspension system block, ARS suspension system block, and ARS linkage connecting the holder towards suspension block
• ARS linkage angle – modified by adding/removing shims on the steering block and ARS-holder – modifications the toe-in characteristics regarding the back tires during framework roll
• Aluminum suspension holders featuring built-in Suspension Settings (ISS) for fast & effortless suspension system geometry adjustment
• Suspension holders enable stronger mounting associated with suspension system hands, and so the suspension geometry of this vehicle doesn't change even with hard crashes
• Suspension mounting system permits very free arm motion, which gives greater traction, smoother driving, and enhanced steering
• Suspension holder system enables suspension hands to be installed independently from bulkheads allowing for elongated chassis flex to generate more traction
• Independent suspension holders allow for more precise and fine set-up corrections via different bushings
• Rear suspension aluminum holders function incorporated toe-in
• C-hubs available optionally in standard caster angles (0°, 2°, 4°, 6°); available in four hardnesses (M – medium, H – difficult, G – graphite and aluminum)
• Hard front steering obstructs increase steering reaction, decrease front side tire overheating in high-traction conditions
• Small, robust steering obstructs created from special proprietary composite product, available optionally in 3 hardnesses (M – medium, H – hard, G – graphite and aluminum), and have 2 Ackermann positions
• Rear uprights give increased security; available optionally in 3 hardnesses (M – medium, H – hard, G - graphite)

• Suspension hands feature incorporated anti-roll club mounts; rear hands function 3 different anti-roll bar mounts for super-fine adjustment of back anti-roll bar
• Suspension arms produced from graphite product for improved traction and security for the car
• Anti-roll bar system is installed toward bulkheads via bearings for extra-smooth movement and maximum accuracy, and part play is eradicated by aluminum bushings
• Anti-roll club height is adjustable via easy screw adjustment… quick & easy
• Front 1.4 mm & rear 1.3mm anti-roll bar wires included
• Easily-adjustable wheel offset utilizing 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) interior gearing for efficient, superior drivetrain
• Premium-qualitydrive belts
• C-hubs with big openings for fast & easy assembly/disassembly of CVDs and ECS drive shafts; prevents 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 between your drive shaft and wheel. With an original 2-piece joint between the axle therefore the wheel, any extreme wheel turning angle is split into two shallower angles without joint binding. Which means that regardless of the cornering speed and wheel angle, the inner wheel will not bind or vibrate. Drive through corners is more stable, more exact, and easier to drive
• ECS drive shafts made from world-renowned, self-developed HUDY Spring Steel hand ground for maximum precision
