A purpose-designed carbon tube can reduce mass in a long wheelie-bar assembly while tuning its stiffness and launch response. Compression stability, impact loading, and end fittings govern the design.
Carbon wheelie bars are prohibited by the published IHRA Top Fuel rules. This highlight illustrates a material concept for other categories where permitted; it is not a Top Fuel replacement recommendation.
Carbon tubes can carry tension and compression with low added mass, making them candidates for a triangulated wing support. Controlling support deflection helps hold the intended wing position under aerodynamic load.
This is a custom structural application. Size for maximum downforce, drag, buckling, vibration, and the full bonded or bolted connection; confirm the competition rules.
Purpose-designed tubular stays can locate a front wing with low added mass and resist movement under aerodynamic load. A short, triangulated load path helps maintain its intended position.
The dragster uses a front wing rather than a road-car splitter. Any carbon support concept requires approved mounting, buckling and connection analysis, and confirmation of the applicable competition rules.
Reaction Composites can wind tubes for torque transmission as part of a custom driveline development program. Tailored composite shafts can reduce rotating mass and tune torsional response in suitable applications.
A rear-engine dragster has a short driveline, shown near the rear axle, rather than a long front-engine driveshaft. This is a custom material concept; stock axial tubes are not finished or approved Top Fuel driveline components.
A well-engineered carbon link can carry axial tension and compression with low moving mass. Tube diameter, laminate, joints, and span determine stiffness and stability.
The model has a rigid front axle and slender steering links, not wishbone suspension. Carbon steering concepts require independent design and testing for an approved application; they are not recommended substitutes for Top Fuel steering hardware.
Lightweight cross-bracing can locate secondary assemblies and reduce relative movement between their mounting points. Carbon tubes are most effective when the intended forces follow a clear axial load path.
These highlighted stays represent auxiliary support concepts. They do not replace required metallic chassis rails, roll-cage members, or other certified primary structure.
Small carbon tubes can support a dashboard, instrumentation, or a lightweight interior panel with little added mass. Short, well-supported spans help keep those accessories steady.
The metallic protective cage stays separate. These accessory supports do not replace roll-cage members, seat or belt anchorages, or required impact protection.
Secondary body stays and compact sensor booms are additional candidates for carbon tubing. Low mass and adjustable tube geometry can help keep instrumentation and removable panels in position.
Use appropriate attachment hardware and check vibration, service access, and the applicable mounting rules. These are custom concepts rather than approved racing parts.

Reducing component weight is useful when the finished assembly also delivers the stiffness and load capacity the application requires. Reaction Composites filament wound carbon fiber tubes provide a starting point for motorsport projects such as chassis bracing, aerodynamic supports, equipment mounts, and lightweight structural assemblies.
Our stock tube architecture emphasizes axial rigidity. Predominantly low-angle carbon fiber reinforcement carries loads along the tube’s length, while an outer ±45° layer contributes shear reinforcement and wall stability. Tube diameter, wall thickness, unsupported length, and end connections determine how that material performs in the finished assembly.
For a brace or support, begin with the expected tension, compression, and bending loads. Account for vibration, repeated loading, mounting details, and nearby heat sources when selecting the tube and its connections.
We can also wind custom tubes for torque transmission and rotating applications, including driveshaft development. These applications require a laminate selected for torsional loading, together with evaluation of rotational speed, critical speed, balance, fatigue, and end-fitting attachment. Stock axial-stiffness data alone does not establish a driveshaft’s suitability.
Temperature is another selection factor. Rated for use up to 250°F; confirmation is required for expected loads or critical applications.
