Chassis

All-new narrower graphite chassis is CNC-machined from 2.2mm thick premium-grade graphite material, and is 3mm narrower than the previous T4’14.

New chassis is specifically designed for different track conditions, and gives increased traction, steering, stability, and improved cornering speed.

Chassis features pre-drilled holes for new ARS™ system.

Chassis features pre-drilled holes for optional parts such as chassis weights, graphite motor guard, graphite adjustable battery holder, and battery strap.

Chassis designed specifically for brushless motors and LiPo batteries; composite battery holders prevent batteries from moving in crashes

Top deck allows installation of optional aluminum stand which changes the car’s flex characteristics

Top deck allows installation of 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) as the bearing is held by the layshaft bulkhead

New upper bulkhead clamps features new, optimized roll center characteristics

Upper bulkhead clamps designed for the new super-narrow placement of the bulkheads

Independent front and rear diff height adjustment and belt tension adjustment in both front and rear bulkheads

3mm thick super-low profile shock towers lower the CG and improve stability

Motor mount bulkhead is compatible with all standard brushless motors

Centered layshaft and split bulkheads provide enhanced balance due to optimum weight distribution of the motor towards centerline, giving quicker left-right transitions

New motor mount bulkhead is now one piece with layshaft bulkhead to eliminate tweak caused by connected screws

Motor mount bulkhead is connected with new alu motor mount plate to eliminate tweak and also offers new flex adjustment possibilities by adding or removing screw in front of the nut or by using optional post instead of the nut.

All-new front/rear lower bulkheads are designed for new anti-roll bar bearing mounting system

Suspension

All-new ARS™ suspension (included) offers great adjustment possibilities and driving characteristics

Kit includes both standard & new ARS™ rear suspensions

ARS™ suspension consist of new ARS™ arms, graphite 0° C-hubs for optimal flex characteristics, hard steering blocks, ARS™ post mounted to the chassis, and ARS™ linkage which connects the post with the steering block

ARS™ linkage angle - which is altered by adding and removing shims on the steering block and ARS post mount – changes the toe in characteristics of the rear tires under rolling effect. When the car is pressed, toe-in can either increase or decrease.

aluminum suspension holders featuring Integrated Suspension Settings (ISS) allow super fast and easy suspension geometry setting

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 diff 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)

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 two hardnesses (M – medium, H - hard), and feature 2 Ackermann positions

New rear uprights give increased stability; available optionally in two hardnesses (M – medium, H – hard)

Rear uprights feature integrated 0° toe-in to prevent suspension geometry changes in serious crashes

All-new arms feature innovative SFATM (Suspension Flex Adjustment, innovative and unique graphite stiffeners that allow for super-quick suspension flex adjustment to easily adjust the traction of the car in 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

Front 1. mm & rear 1.3mm anti-roll bar wires included

Easily adjustable wheel offset using optional shims or optional offset wheel hubs (-0.75mm, +0.75mm, +1.5mm)

All-new 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 a screw… quick & easy.

Drivetrain

Lightweight middle layshaft CNC-machined made 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, reinforced drive belts

C-hubs with large openings for quick and easy assembly/disassembly of the CVDs; prevents collision of CVD with C hub in serious crashes (compatible with the ECS drive shafts)

Super-light drive axles have 35% less rotating mass

Super-lightweight Swiss 7075 T6 aluminum rear drive shafts (50mm), hard-anodized, color-coated and laser-engraved, 38% lighter than standard drive shafts

Differentials

Composite hubs for differentials to fit super narrow bulkheads

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 near 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

New servo mount and graphite servo holder are mounted to the chassis with 3 screws to eliminate the possibility of servo movement under hard crashes

New servo mount includes extra hole where the battery backstop screw can be mounted

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

Shock shafts are specially hardened for maximum strength

Foam inserts for perfect shock rebound

Super Short Shock Springs (4S) developed & designed for the new SLP shocks

C2.5 springs included in the kit are shortened to fit new 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
