Design and handling highlights: the MR-04's lower battery mounting and revised steering geometry reduce scrub and rotational resistance, producing sharper, more linear steering and improved cornering stability. Front suspension links maintain optimal tire contact through camber alignment changes during movement, and the rear uses a coil spring damper for added stability (upgradable to optional oil-filled shocks). The flexible T-bar rear suspension plate helps isolate the rear pod for effective suspension action, and all axles use low-rotational-resistance ball bearings to keep the drivetrain efficient. A parts set is included to adjust front tread for alternate bodies, and rear tread can be altered via wheel offset changes. The transmitter provides trims, dual rate steering adjustment and a training mode (default) for reduced speed control—ideal when introducing new drivers to the hobby.

Whether you want a compact indoor racer or a detailed display model, the Kyosho McLaren 12C RC MINI-Z MR-04 Readyset balances realism, tuning potential and out-of-the-box usability.
