In-Depth Features
| Feature | Details |
|---|---|
| Drive | Dual-belt system with 5 mm-wide belts for optimized efficiency. Both belts feature ball-raced belt tensioners. |
| Chassis | The 5 mm aluminum chassis features a symmetrical design for balanced flex and weight distribution. Countersunk holes and chamfered edges improve cornering clearance and ground clearance. All underside screws use a 2.5 mm Allen size. Multiple pockets reduce weight while maintaining stiffness. An optional full carbon fiber chassis is available and weighs approximately 90 grams less. |
| Top Deck | The 2.5 mm carbon fiber top deck creates a strong, rigid connection between the front and rear sections. The servo is mounted centrally and accommodates large or low-profile servos. The center section also provides space for the receiver, which can be attached to the small plate or clips. |
| Battery Holders | Strong carbon fiber battery holders adjust to fit most popular 2S and 3S battery packs. The flexible mounting system allows batteries to be moved forward or backward to adjust the car's balance, steering, and grip. The low, central battery position helps achieve a low center of gravity. |
| ESC | A strong carbon fiber speed controller plate accommodates most popular ESCs. The plate and attached ESC can be removed easily. |
| Motor Holder | The precision-machined 8 mm aluminum motor holder creates a durable assembly capable of handling the high power of brushless motors. It connects to the rear bearing blocks for a structure that is both stiff and flexible. Gear mesh can be adjusted easily from underneath the car. The kit includes a 14T pinion; other pinions are available separately. |
| Mid Shaft | A 7075-T6 aluminum mid-shaft holder supports the mid-shaft and spur gear. The described gearing is 14T/48T, allowing the spur gear to be changed quickly and easily. |
| Body Posts | Durable aluminum front body posts feature an eccentric design, allowing the body to be shifted forward or backward by a few millimeters to optimize steering and downforce. |
| Steering Blocks | The steering blocks can be installed on either side and allow axle position adjustments forward or backward for trailing or leading steering geometry. They also provide kingpin inclination and offset adjustments. Spring steel steering rods attach to aluminum steering plates on the steering blocks. Optional carbon fiber disks can be installed on the sides to increase stiffness and improve aerodynamics. Identical left and right steering blocks feature an aluminum steering-rod connector with two Ackermann settings. The steering blocks and rear uprights connect to the arms through 8.5 mm spring steel pivot balls, which run smoothly inside protective nylon cups and are easily adjusted with an Allen tool. |
| Front Suspension Arms | Long, durable front lower wishbones sit low in the chassis and feature a partially covered section for the inner suspension pin and front anti-roll bar pivot link. They also include an extension for the down-stop screw. The lower arms support an aluminum shock mounting plate for a higher and farther-out front shock position. Strong upper arms can be used on either side. The lower arms connect to the aluminum front bracket through low-profile nylon holders, with low and super-low versions included. This design also allows quick front driveshaft replacement. Longer upper arms fit between anodized aluminum top brackets, which hold suspension pin inserts for three camber adjustment options. Spacers beneath the top brackets adjust angle or height. Caster spacers clip onto the upper pivot pins, and similar clips on the lower pins adjust wheelbase. A top-mounted composite bracket stiffens the front section, supports the 3 mm carbon fiber front shock tower, and accommodates the down-stop screws. |
| Anti-Roll Bars | The ball-raced front anti-roll bar uses a wire design with easy front access and is held by aluminum front braces. The standard wire is 2.5 mm, with two optional sizes available. The pivot-ball linkage transfers force smoothly and allows easy adjustment using a captured pivot ball. The rear ball-raced anti-roll bar is mounted in steel adapters running in nylon spacers inside the aluminum holders integrated into the rear brackets. It also comes with a standard 2.5 mm wire and two optional sizes. Adjustable track-rod linkages connect the bar to the rear lower arms. |
| Front One-Way Axle | The front assembly features a black-anodized aluminum axle with Japanese-made one-way bearings and a precise, play-free pulley assembly. It includes spring steel drive cups, long and thin high-strength spring steel driveshafts with a CVD system, and ball-raced spring steel wheel axles with aluminum quick-change levers. The open front-end design allows fast, easy removal of the front axle and its components. |
| Servo Saver | The spring-loaded servo saver allows quick, easy Ackermann adjustments. Its top-mounted insert provides three positions, with two additional Ackermann positions available on the steering blocks. The precision pulleys feature holes in their side flanges to help dirt and dust escape. |
| Rear Brackets | Aluminum brackets support the rear axle. The open design simplifies maintenance and cleaning and requires few screws for disassembly. Belt replacement is quick and straightforward. An eccentric on the rear shaft allows belt tension adjustment. The suspension bracket and rear plate securely hold the pins and feature composite roll-center inserts for fast, precise adjustments. |
| Rear Axle | A solid rear axle features a lightweight 48T pulley made from Serpent spring steel, measuring 9 mm wide with four slots for the pin. |
| Drivetrain | The rear drivetrain uses strong spring steel driveshafts, spring steel wheel axles with aluminum quick-change levers, and a spring steel rear axle for durability and long service life. |
| Rear Wishbones | Long, durable rear lower wishbones can be used on either side. Each lower arm supports a low-mounted rear anti-roll bar link and an aluminum rear shock mounting plate, allowing the shocks to sit farther back and outward for optimized geometry and performance. The arms also provide easy access to down-stop screws. Nylon clips on the lower rear pins adjust the wheelbase. |
| Uprights | Durable composite uprights support ball-raced spring steel wheel axles with aluminum quick-change levers. The 8.5 mm pivot balls allow quick camber adjustments using smooth, hex-shaped plugs. Floating body mount arms attach to the top of the uprights. Spacers beneath the upper pivot balls adjust roll center and camber change. Optional carbon fiber disks can be fitted to the sides for aerodynamic benefits. Adjustable rear upper camber links attach to the rear carbon camber plate, which offers two positions. |
| NSK Bearings | The kit features high-speed NSK ball bearings, most of which are sealed and use aero-shell lubrication or grease. All bearings, except those in the servo saver and brake cam, are seated in nylon bushings to reduce vibration and play. |
| Shocks | The latest short Serpent big-bore shock absorbers feature membranes. Threaded bodies and adjustment nuts with internal O-rings make ride-height adjustments easy and precise. Front and rear shocks are identical, smooth in operation, and easy to assemble and fill. The X-rings are pre-oiled. Shock springs are selected, matched, flat-ground, and color-coded. |
