In-Depth Features:

  • General:
    • Designed for highest performance at all levels of racing
    • Chassis designed to provide maximum traction and steering
    • Reduced sensitivity to changing track conditions, giving super-consistent performance during runs
    • EFRA, ROAR, FEMCA spec compliant for stock and modified racing
    • Manufactured from premium European materials, machined using state of the art Swiss and German machines
  •  Chassis:
    • Alu Flex chassis CNC-machined from 2.0mm 7075 T6 Aluminum
    • Top deck allows installation of optional aluminum stand to change flex characteristics, and optional graphite steering system plate
    • Bulkheads have been strategically placed closer to the center of the chassis to improve steering, traction, and stability
    • Layshaft bulkhead allows removal of top deck attachment screws (front, rear, or both); bearing is held by layshaft bulkhead
    • Upper bulkhead clamps feature  4 optimized roll center positions
    • Front & rear bulkheads allow independent front & rear diff height adjustment and belt tension adjustment
    • 3mm super-low profile shock towers lower the CG and improve stability
    • Front & rear lower bulkheads accommodate the anti-roll bar bearing mounting system
  • Suspension:
    • Kit includes both standard & ARS™ (Active Rear Suspension™) rear suspensions
    • 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
    • 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 holder system allows suspension arms to be mounted independently from bulkheads allowing for elongated chassis flex to generate more traction
    • 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)
    • Hard front steering blocks increase steering response, decrease front tire overheating in high-traction conditions
    • Small, robust steering blocks made from special proprietary composite material, available optionally in 3 hardnesses (M – medium, H – hard, G - graphite), and feature 2 Ackermann positions
    • 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)
  • Drivetrain:
    • 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, Kevlar®-reinforced 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
    • Super-lightweight wheel axles manufactured from premium HUDY Spring Steel™
    • 7075 T6 aluminum wheel hubs
    • Complete set of high-speed, blue-sealed ball-bearings are degreased and lightly oiled for maximum efficiency, individually controlled, selected, and inspected
  •  Differentials:
    • Composite hubs for differentials to fit super-narrow bulkheads
    • Super-smooth, super-light maintenance-free composite gear differential
    • Super-light composite Front Solid Axle with XRAY’s own smart quick-change outdrive system for easy outdrive exchange; no servicing or replacement of drive shaft blades needed, translates into reduced servicing costs
  •  Steering:
    • 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
  •  Shocks:
    • Super-Low Profile (SLP) aluminum shocks for lowered CG and improved stability
    • SLP aluminum shocks have been shortened by more than 7mm to provide maximum stability under all track conditions, while reducing traction roll under high-traction conditions
    • Foam inserts for perfect shock rebound
    • Super Short Shock Springs (4S) developed & designed for the SLP shocks
    • C2.5 springs included in the kit are shortened to fit SLP shocks and the spring rates have been optimized to provide maximum steering and traction
    • XRAY self-developed and manufactured 4S springs are manually selected for maximum precision, equal length, and equal damping characteristics
    • Race-tested and tuned shock positions
  •  Bumper & Body Mounts:
    • Front body mounts shortened to lower CG
    • Front upper and lower composite bumper made from specially-formulated material to withstand hard impacts
    • Super low-profile foam bumper made from lightweight, high-resilience foam
    • Foam bumper is larger for perfect body fit
    • Foam bumper is made from updated strong but lightweight material for improved durability but keeping the weight as low as possible
    • Composite bumper upper holder brace helps to reduce chassis breakage in hard crash
