Bulkheads.

The new bulkheads were reconfigured to achieve a lower CG and reduce weight to improve stability while also eliminating tweaking issues in serious crashes. The bulkheads are 5mm lower and 4g lighter comparing to previous versions. The bulkheads use two centering holes instead of one to eliminate tweak issues in crashes. The rear bulkheads feature smaller and lighter eccentric bushings with finer steps for improved ride height adjustability and a lower center of gravity. The smaller ride height eccentrics allow for more compact bulkhead dimensions to reduce weight and lower CG. The graphite rear brace is thinner and lighter for improved CG and flex of the POD. The rear brace mounts to the bulkheads from the top instead of the rear for improved tweak resistance but only uses a single mounting point instead of two for improved flex of the rear POD.

The bulkheads are a 1-piece tweak-free design which is more rigid and robust. The lower profile of the bulkheads and redesigned upper plate help to reduce the overall CG of the assembly.

The bulkheads feature centering pins on the top and bottom surfaces that align the upper and lower pod plates 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 uses 4 mounting screws to secure it to the bulkheads.

The 1 piece bulkheads in the X12 utilize eccentric bushing inserts for the rear axle height adjustment.

Our race proven ball differential is still available as a tuning option if needed for low grip situations.

The rear differential features high-grade precision carbide balls in the spur gear, hardened and precision-ground D-steel shims, and premium carbide axial thrust-bearing.

Shock Absorber.

The center shock has new geometry with the mounting point moved further back for quicker direction change, as well as improved on-power steering.

The shock features a new stiffer spring for improved steering and response.

The center shock has an optimized geometry with the mounting point very far back, for a quicker direction change, as well as maximum on-power steering.

The shock features a stiff spring for the best possible steering and response.

The fully-adjustable shock features an aluminum shock body that is hard-anodized for ultra-durability. The fine-threaded shock body allows for quick and easy shock spring preload adjustment.

Tiny, thin shock membrane gives smooth dampening characteristics, and a super-soft silicone shock O-ring gives super-smooth operation while preventing oil leakage.

The ultra-finely finished shock shaft with precise-molded composite shock piston ensures optimum shock oil flow and smooth shock absorber action.

Low Profile Bushings.

Lightweight low-profile bushings installed in the graphite plates replace traditional locknuts for a sleeker look while lowering CG, and simplified assembly eliminating the additional wrench needed for M3 nuts.

Servo Holders.

The ultra-low CG servo mounting system places the servo directly on the chassis to improve the steering response, and with adjustable grooves in the chassis to place both small and micro size servos into the absolute center of the chassis.

The servo holders feature an additional hole to fit micro servos such as Sanwa SRG-HR, HS and PGS-HR, while the standard positions still accommodate the standard 1/12 servo dimensions.

Servo Position.

Unique & innovative fully-adjustable servo mount allows easy adjustment of the servo position. The servo is attached to independent mounts that are mounted using a groove in the chassis. Depending on the size of your servo, you can easily install and adjust the servo and its position to the center of the chassis.

Bumper Holder.

Front bumper design and size designed to meet the latest racing organization rules.

Machined from premium 2.5mm graphite, the brace is flexible yet rigid enough to withstand serious crashes.

Front Wheelbase.

The X12 chassis features XRAY self-developed front wheelbase adjustment possibility. The chassis has two positions for front suspension mounting; the whole front suspension can be easily moved by 2mm frontwards or rearwards.

The long wheelbase is the same wheelbase as previous X12 cars, and is recommended for larger tracks or tracks with longer sweepers. A long wheelbase works well at low-to-medium traction tracks when more stability is desired. Also better suited to the Open Modified classes to make the car smoother and less twitchy.

The short wheelbase allows the car to rotate better in the middle of the corner to maintain cornering speed. Recommended for tight, technical tracks or tracks with numerous hairpin corners. The short wheelbase works well at medium-to-high traction tracks where a lot of steering is needed. Also better suited to the Stock and blinky classes.

Front Ride Height.

The front suspension uses ride height adjustment shims for very quick, precise, and hassle-free ride height adjustment depending on track conditions. The set of 0.2, 0.4, and 0.6mm ride height adjustment shims are included for fine tuning. 

Side Tubes.

Lateral damping side tubes provide ultra-smooth side damping, making the car easier to drive and easier to work on. The outer aluminum tube and inner Delrin® tube operate ultra-smoothly.

Servo Saver.

The XRAY servo saver has become the industry-standard saver and remains unchanged and is included.

Several linkage mounting positions are offered to make the steering linkage adjustment easier. The servo saver consists of 4 springs which makes the servo saver strong enough to provide the precise steering racers demand, while still being flexible enough to prevent servo damage in hard crashes. The servo saver has interchangeable bushings to fit most popular servos.

Side Springs.

Side springs are placed directly on the chassis for smooth and precise movement.

Spur Gear.

Precision-molded spur gears are made from XRAY's exclusive composite material, ensuring true running, super-quiet operation, and robustness for handling powerful motors. A range of optional spur gears for fine tuning is available.

Gear Differential.

The optional XRAY self-designed, revolutionary, super-smooth gear diff is a direct replacement for the ball-differential.

Using the optional gear differential makes the car more stable and easier to drive, especially in high-traction conditions. The gear diff increases on-power steering which is needed on almost all types of tracks. A “must have” for every racer.

The complete gear differential set includes a composite case and cover, precision-molded internal satellite gears made from special XRAY-developed composite material, all ensuring long lifespan and super-smooth efficient operation. A super-strong hollow steel shaft ensures maximum reliability and strength.

The advantage of the gear diff is that it is maintenance-free. When the diff is correctly built, there is no need for maintenance for a very long time, no need for frequent oil changes, and no leakage due to a superior sealing system.

Body Posts.

Robust body posts with fully-adjustable body holders; optional super-fine +1 or +2mm body backstops available optionally for even more super-fine body height adjustment. 

Weight Balance.

The layout of the electronics and position of individual sections of the car were designed with optimum weight distribution and balance in mind.

The steering servo is located in a lay-down position for lowest CG at the chassis center, and the layout of the chassis allows the batteries to be placed either cross or inline.

Depending on battery configuration, the ESC and receiver can be placed in various positions for ideal weight transfer and balance.
