Precision 7075 chassis for improved handling

Owners of the Mugen Seiki MRX4 and MRX4-R can fit the 3Racing MRX4-12/TI 6mm 7075 aluminium main chassis to create a firmer platform. This precision-engineered part focuses on durability and consistent response.

Engineered for tighter control

The 7075 aluminium construction and 6mm thickness reduce unwanted flex under load, helping suspension settings remain stable during cornering and jumps. That lets drivers tune with more confidence.

Compatibility with MRX4 family

Manufactured to match the layout of the Mugen Seiki MRX4/MRX4-R series, this chassis offers a close fit for a direct upgrade. It is a common choice when replacing an aged or damaged original plate.

Material selection rationale

7075 is selected for its favourable strength-to-weight ratio, delivering increased rigidity with controlled mass. 3Racing uses this alloy to balance stiffness and usability on race circuits.

Is the chassis compatible with aftermarket hop-ups?

Yes. Standard aftermarket brackets and reinforcement parts that follow the MRX4 mounting pattern should be compatible, but check clearances for thicker upgrades.

Can this plate be drilled for weight tuning?

Minor modifications are possible but proceed with caution, as removing material will alter stiffness characteristics; test changes incrementally.

Will this suit both race and club tracks?

Yes. The chassis provides a firmer baseline that is beneficial across many track types, though final setup should be tuned to the surface and grip level.
