Front left and front right 50g brass weights are moved from the bumper under the front driveshafts into the center of the front drive train for improved weight transfer on & off power. These weights makes the car better balanced and improves its rotation.
CNC-machined from brass material, black color coated and laser engraved.
The one-piece carbon Multi-Flex™ top deck has a narrow shape for easier installation, improved handling characteristics and features 8 different flex options.
The one-piece top deck offers increased flex, which makes the car softer. Suggested especially for low traction conditions where it removes a bit of initial steering but generates more mechanical traction.
The top deck can be modified by making additional cuts, to provide more additional flex set-up options.
The machined ultra-precise top deck screws ensure the top deck is mounted completely tweak-free to improve flex characteristics.
The shape of the top deck is specifically designed to achieve maximum traction and great steering characteristics at the same time.
CNC-machined from premium high-grade carbon fiber material made in USA.
• Lengthens upper arms
• Reduces camber gain
• Improves mid corner steering
• Reduces traction rolling
• For high traction & fast tracks

The upper clamps move the inner pivot 1mm closer to center. This position lengthens the upper arm and reduces camber gain to free up the car. Mid corner steering improves in long sweepers, and traction rolling is reduced in very high traction carpet conditions. Recommended for large open tracks or high traction carpet tracks.
Heavy duty upper clamps improve durability in hard crashes and accommodate the inner shock mounting system.
The upper clamps use caster inserts for quick and easy set-up changes, and feature centering pins for precise installation and improved crash reliability.
The screws installed from the bottom of the caster inserts capture the inserts in the upper clamps to secure the inserts while servicing the car. The screws also serve as the upper arms pivot ball mounts, reducing the number of components in the assembly and reducing weight.
The upper clamps and caster inserts are made from premium Swiss 7075 T6 aluminum and black anodized.

Alu flex chassis is recommended for high traction carpet tracks. Makes the car easier to drive and more stable in high traction condition and avoids traction rolling. Chassis is 2mm thick, made from 7075 T6 aluminum and features special cut outs for optimal flex characteristics. The ultra-narrow chassis is only 84mm wide and features special cut outs that provide the chassis flex characteristics suitable for a wide variety of the traction levels. The bottom of the chassis is shaped to reduce contact between the chassis and the ground while turning to improve cornering speed.
• One piece top deck for multiple flex adjustments
• Provides higher flex than two-pieces top deck
• Suggested for low traction conditions
• 8 different flex adjustment points
• Easy installation & removal of the spur gear
• 2mm graphite
• Fits X4F’24

Front part of the split upper deck. The split (2 piece) top deck is recommended mainly for asphalt tracks. The top deck features milled holes for special tweak-free top deck screws. The top deck offers more steering response, and more on power steering. The flex characteristic is different than the kit top deck, and the 2 pieces allows for more flex options, which can be adjusted individually between the front and rear.
Machined from 2.0mm graphite material, the shape of the top deck has been specifically designed to achieve maximum traction and great steering characteristics at the same time.

The top deck can be connected to the motor mount using these alternatives:
1.) Soft setting - Only one rear screw is used. This allows maximum flex and provides maximum steering. However, the car is less stable on-power.
2.) Stiff setting - Both screws are used. This setting gives reduced flex, rotation is decreased. This setting provides maximum stability and makes the car easier to drive.
