  • Motor mount bulkhead is combined with layshaft bulkhead in 1 solid piece to eliminate tweak caused by connected screws
  • Motor mount bulkhead is connected with alu motor mount plate to eliminate tweak, also offers multiple flex adjustment possibilities by adding/removing screw ahead of the nut, or by using optional post instead of the nut.
  • The motor mount plate is connected to the chassis via an M3 nut and an extra countersunk screw can be placed ahead of the nut if more reinforcement is needed, or the nut can be removed and 1 of 2 holes can be used as extra flex adjustment options.
  • Front & rear lower bulkheads accommodate the anti-roll bar bearing mounting system 



  • Kit includes both standard & ARS™ (Active Rear Suspension™) rear suspensions
  • ARS™ suspension offers great adjustment possibilities and driving characteristics
  • ARS™ suspension consists of ARS™ arms, graphite 0° C-hubs for optimal flex characteristics, hard suspension block, ARS™ suspension block, and ARS™ linkage connecting the holder to the suspension block
  • ARS™ linkage angle – adjusted by adding/removing shims on the steering block and ARS™-holder – changes the toe-in characteristics of the rear tires during chassis roll.  
  • Aluminum suspension holders featuring Integrated Suspension Settings (ISS) for quick & easy suspension geometry adjustment
  • Suspension holders allow more durable mounting of the suspension arms, so the suspension geometry of the car does not change even after hard crashes
  • Suspension mounting system allows for very free arm movement, which gives higher traction, smoother driving, and improved steering
  • Suspension holder system allows suspension arms to be mounted independently from bulkheads allowing for elongated chassis flex to generate more traction
  • Independent suspension holders allow for more precise and fine set-up adjustments via different bushings
  • Rear suspension aluminum holders feature integrated toe-in
  • C-hubs available optionally in standard caster angles (2°, 4°, 6°); available in three hardnesses (M – medium, H – hard, G - graphite)

  • Rear uprights give increased stability; available optionally in 3 hardnesses (M – medium, H – hard, G - graphite)
  • Rear uprights feature integrated 0° toe-in to prevent suspension geometry changes in serious crashes
  • Arms feature innovative SFATM (Suspension Flex Adjustment), innovative and unique graphite stiffeners allow for super-quick suspension flex adjustment to easily adjust the traction of the car under various track conditions
  • Suspension arms feature integrated anti-roll bar mounts; rear arms feature 3 different anti-roll bar mounts for super-fine adjustment of the rear anti-roll bar
  • Suspension arms made from graphite material for improved traction and stability of the car
  • Anti-roll bar system is mounted to the bulkheads via bearings for extra-smooth movement and maximum precision, and side play is eliminated by aluminum bushings.
  • Anti-roll bar height is adjustable via simple screw adjustment… quick & easy
  • Front 1.4 mm & rear 1.3mm anti-roll bar wires included
  • Easily-adjustable wheel offset using optional wheel hubs  (-0.75mm, +0.75mm, +1.5mm)



  • Lightweight middle layshaft CNC-machined from aircraft aluminum
  • 84T 48P spur gear  – extra-hard material, wobble-free design
  • 38/20T (1.9) internal gearing for efficient, high-performance drivetrain
  • Premium-quality drive belts
  • C-hubs with large openings for quick & easy assembly/disassembly of the CVDs and ECS drive shafts; prevents collision of CVD or ECS drive shafts with C‑hub in serious crashes
  • Super-light drive axles have 35% less rotating mass
  • Front Extra-Strong ECS drive shafts equalize the speed between the drive shaft and the wheel. With a unique 2-piece joint between the axle and the wheel, any extreme wheel turning angle is divided into two shallower angles without joint binding. This 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 precise, and easier to drive.
  • ECS drive shafts made from world-renowned, self-developed HUDY Spring Steel™; hand ground for maximum precision
  • Super-lightweight Swiss 7075 T6 aluminum rear drive shafts (50mm), hard-anodized, color-coated and laser-engraved, 38% lighter than standard drive shafts

  • Servo mounting system for improved balance and elimination of unwanted tweak
  • Servo mount allows the servo to be suspended into the chassis centerline, providing better balance while eliminating tweak and allowing for additional traction
  • Steering is isolated from chassis flex, ensuring tweak-independent steering for super-precise and consistent steering characteristics
  • Servo mount and graphite servo holder are mounted to the chassis with 3 screws and 2 centering posts to eliminate the possibility of servo movement under hard crashes
  • Servo mount includes extra hole where the battery backstop screw can be mounted
  • Servo mount includes extra hole for in-line flex adjustment system
