Chassis.

The chassis was redesigned to accommodate the all-new Tweak-Free Pod System and side braces.

The X1 2021 chassis continues to offer a wheelbase adjustment using one of three mounting positions for the front suspension. Depending on the installation choice, wheelbase can be selected from the standard length or +/- 4mm alternatives.

The super-narrow chassis creates maximum traction while still having excellent steering and cornering speed. The chassis torsional stability also helps eliminate the scrub effect in high-speed corners.

An optional chassis plate machined from a stiffer graphite material was developed for very high traction conditions or for tires that offers a lot of steering which makes the standard car more difficult to drive. This optional chassis makes the car more stable and easier to drive by reducing oversteering problems.

Rear POD.

The rear suspension of the X1 incorporates many of the improvements found in the new X12 2021 pod design including the all-new Tweak-Free Pod Mounting System. The new pivot system improves traction and stability, and it eliminates tweak issues after crashes.

The all-new pod assembly includes black anodized aluminum bulkheads and revised graphite upper and lower pod plates. The new one-piece rear bulkheads achieve maximum durability compared to previous configurations and use traditional eccentric inserts to adjust rear axle height in 0.5 mm increments.

The all-new graphite upper plate was redesigned to mount to the bulkheads with centering pins and 4 screws to secure the assembly in proper alignment and to minimize the chances of tweak after an impact on the track.

POD Mounting System.

All-new aluminum Tweak-Free Pod Mounting System improves traction and vehicle stability, plus it helps eliminate tweak issues after crashes. The new system allows for a significantly lowered roll center, a lowered center of gravity, and a new pivot height adjustment using different shims.

The pod mounting position choices include the standard rearward mounting position where the center pivot is located in-line with the side link pivot balls on the rear pod plate, and the new forward location that places the pivot 2mm forward of the link mounting points. This adjustment has a significant effect on the cornering feel:

• Forward – Good balance between front and rear traction. Well suited for most conditions.
• Rearward – Increases steering and more rotation from rear end. Intended for high grip carpet.

Bulkheads.

The all-new bulkheads are a 1-piece tweak-free design that is more rigid and robust.

The new bulkheads feature centering pins on the top surface that align the upper pod plate during assembly and prevent movement between the components during a crash. To further enhance the assembly s strength and resistance to tweak, the upper pod plate now uses 4 mounting screws to secure it to the bulkheads

The 1-piece bulkheads utilize eccentric bushing inserts for the rear axle height adjustment.

CNC-machined from premium extra-hard Swiss 7075 T6 black-coated aluminum for extended life and a stylish look.

Rear Ride Height.

The X1 2021 bulkheads allow for very quick & easy ride height adjustment using eccentric axle holder bushings. The axle height is adjustable in 0.5 mm increments over a 5mm range. Smart & easy.

Rear Pod Upper Plate.

The all-new graphite upper plate now mounts to the bulkheads with centering pins and 4 screws to secure the assembly in proper alignment and to minimize the chances of tweak after an impact on the track.

The rear pod upper plate is the base for the center shock and the side tubes. Machined from premium high-grade graphite, the pod plate is very strong and gives rigidity to the entire rear assembly.

The side tubes mount to the rear pod upper plate to control pod movement in standard configuration, and an optional side shock is available for those that prefer the single damper design.

Side Braces.

All-new graphite side braces are mounted to the rear brace, extending forward along the edge of the chassis. The braces are secured to the chassis via aluminum posts and offer three flex settings to alter the chassis characteristics for different track conditions.

Rear Link Brace.

To integrate with the new chassis side braces, the rear link brace was redesigned as part of the chassis Multi-Flex system and also functions as the mounting point for the independent wing mount system.

The rear link brace design allows for a wide range of battery placement adjustments and features a convenient O-ring battery mounting system.

The graphite rear link brace is the mounting point for the side tubes and side springs, and functions as a backstop for the battery pack as well.

Front Suspension.

The front suspension was redesigned for improved reliability, strength, lowered CG and improved ease of adjustment. Front upper arms, front lower arms, anti-roll bar mounting system, kingpin axles and mounting stands are all new. The new system features a unique front tube system for a simple roll adjustment for the front suspension.

Front Lower Arms.

The front lower arms were redesigned to allow access to the new front tube.

The shape of the arm is designed to be more robust for improved durability. The extra material reinforces the arm and prevents it from bending in hard crashes. The arm also incorporates an access window to reach the new front tube for easier installation and tuning.

The arms special graphite material with a stronger compound hardness reduces flex, increasing stability and improving drivability in high traction conditions.

The front lower arm also features two mounting positions to set the car s front width.

The softer front lower arms from previous X1 versions are still available as options and are recommended for use on low-traction tracks, or when using harder front tires, to generate more steering.

Front Tube System.

All-new front upper arm allows to mount the front tube which helps to adjust the hardness of the front suspension. Depending on the traction conditions and surface, the front tube helps to adjust front suspension for particular track conditions.

Using thicker oil on the front tube makes the car less responsive but easier to drive and increases stability.

Softer oil improves cornering speed and steering but makes the car a bit more difficult to drive.

Front Upper Arms.

The front upper arms were redesigned to accommodate the all-new front tube system and the new low CG anti-roll bar mounting.

Anti-roll Bar.

The X1 2021 features a new aluminum anti-roll bar holder system integrated with the front body and wing mount that lowers the overall CG.

The wobble-free, fully-adjustable wire anti-roll bar system is mounted in holders that are now located on the front wing mount plate via bearings for extra-smooth movement and quick & easy changes and adjustment. The roll bar turns in ball-bearings for maximum precision and free movement. Anti-roll bar height is adjustable via a ball screw.

Kingpin.

The super-smooth, hardened steel kingpins are 3mm longer than on the previous X1 for even greater front droop adjustment range to better set up the car on various traction conditions and track layouts.

Black Stealth.

All aluminum parts are now black anodized for a great stealth looking design.
