    • The motor mount plate is connected to the chassis via an M3 nut and an extra countersunk screw can be placed ahead or behind the nut if more reinforcement is needed, or the nut can be removed and 1 or more of 6 holes can be used as extra flex adjustment options
    • 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 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 (0°, 2°, 4°, 6°); available in four hardnesses (M – medium, H – hard, 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 special proprietary composite material, available optionally in 3 hardnesses (M – medium, H – hard, G – graphite and aluminum), 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
    • 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
    • Aluminum self-locking wheel nuts

     

    Differentials

    • Super-smooth, super-light maintenance-free composite gear differential
    • Adjustable gear differential stiffness via oil viscosity
    • 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

    • Ultra- Low Profile (ULP) aluminum shocks for even lower CG and improved stability
    • ULP aluminum shocks have been shortened by  4mm comparing to SLP shocks to provide maximum stability under all track conditions, while reducing traction roll under high-traction conditions and to make the car easier to drive
    • Shock shafts are specially hardened for maximum strength
    • Foam inserts for perfect shock rebound
    • Super Short Shock Springs (4S) developed & designed for the SLP shocks
    • C2.5 springs included in the kit to fit ULP 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
