| Chassis. |
|
| The X8 features a unique sandwich chassis design with a battery tray that is integrated from the top for longitudinal reinforcement of the lower chassis plate. The battery tray and lower chassis work together in a uniform flex system. |

|
| Battery Tray. |
|
| The unique battery tray system of the X8 works together with the lower chassis plate in a uniform flex system. |

|
| Chassis Flex. |
|
| The uniform flex system of the chassis allows to adjust different flex characteristics to adjust the car to all different track conditions. By adding or removing the screws on the front chassis brace the flex can be adjusted from very soft up to very stiff. |

|
| Battery Mounting. |
|
| Wicket bracket keeps the batteries apart with a gap in between for independent battery flex in the battery tray as well to improve cooling of the batteries. |

|
| Bulkheads. |
|
| The aluminum bulkheads are designed to join the lower chassis plate and battery tray together in a durable, efficient, and lightweight design. The bulkheads provide optimal stiffness, flex and handling characteristics, even when using harder foam tires. |
|

|
| Front End. |
|
| The graphite plate of the front suspension connects to the aluminum bulkheads with the servo and steering directly attached to it. The front assembly is attached to the chassis through an aluminum pivot ball holder for rigid and precise operation. |

|
| Front Pod. |
|
| Fully independent front pod moves on the pivot balls to ensure maximum performance from the front suspension. There are two different pod stiffness adjustment alternatives that can be used for easy adjustment to fit individual preferences. |

|
| Rear End. |
|
| The entire rear end is mounted on the lower chassis independent of the radio tray. The rear section features a graphite rear bumper that protects the car from back markers and serves as a convenient location to hold the car. |

|
| Belt & Belt Tensioner. |
|
To increase the reliability and strength, the 4WD system features a wide 6mm low friction belt. The reinforced high-efficiency low-friction drive belt ensure that power is properly and efficiently transferred to all drivetrain parts.
The multiple flanged bearing belt tensioner system allows for a smooth and reliable drivetrain. The superior belt tensioning system requires less tension, allowing more chassis flex for improved handling without fear of belt skip issues. |

|
| Caster & Axle Height. |
|
| Adjusting the front caster is a very simple process, made by loosening four (4) screws and moving the upper graphite plate to one of three adjustment positions. The three caster settings are 10°, 13.5° and 17°. |

|
| Servo Saver. |
|
| The servo saver has a short stand to match the low height of the battery tray and a key-lock system that ensures the servo saver will stay secured even during chassis flex in extreme conditions. |

|
| Front Offset & Track Width. |
|
| Front track width is easily adjustable via steering block pivot balls, and the front offset is adjusted by 0.5–2.5mm using included shims. This alters steering geometry & steering characteristics. |

|
| Rear Track Width. |
|
| Rear track width is adjusted by adding or removing shims & wheel pins on the rear axle. It’s adjustable in a range of 3mm. |
|

|
| Rear Body Holders. |
|
The rear body holders can be moved frontwards or rearward together with the body by 2mm. The side holder posts are fully adjustable to ensure the body is properly supported at the desired height. The high level of stiffness prevents body flex during high speeds to maintain consistency and stability from the handling.
The rear body mount holder accommodates mounting of all popular racing bodies and meets all rules. The reinforced body mount is reliable and durable to withstand hard crashes. |
