Race-Oriented Rear Body Post

The 3RACING Auper D6 Aluminum Rear Body Post in red is engineered to provide a firm, repeatable rear mount for competitive setups. Its aluminium construction reduces flex at the mounting point, which helps maintain consistent body height and aerodynamic behaviour during aggressive driving lines.

Chassis Compatibility and Tuning

Optimised for the Auper D6 platform, this post is suitable for fine tuning body position across 1/10 touring chassis that share similar mount geometry. Use it as part of a setup change to evaluate aero and balance differences between bodies.

Fitting Procedure for Track Use

Install with correct-length fasteners and verify that the post sits perpendicular to the chassis plate. For track use, consider pairing with hardened screws and inspect mounting points between heats to ensure no loosening that could affect lap times.

How does this affect aerodynamic tuning?

A secure, non flexing rear mount helps keep the body in the intended aero position, which makes aerodynamic testing more repeatable between runs.

Which fasteners are recommended for circuit use?

Use medium strength thread lock with hardened or alloy screws sized to the original thread; this reduces the chance of mid-session loosening without damaging aluminium threads.

Any checks to perform after installation?

Confirm parallel alignment to the chassis plate, verify body peg alignment, and run a brief shake test to ensure no movement before track sessions.
