Kyosho MINI-Z RC Car MR-04 Audi R8 LMS RTR

The Kyosho MINI-Z RC Car MR-04 Audi R8 LMS Readyset brings full-scale handling traits to a compact indoor racer. It arrives factory-assembled with a pre-painted, display-quality body and the Syncro KT-531P transmitter so you can drive right away after installing batteries. The MR-04 chassis lowers the center of gravity and updates steering geometry for sharper handling and smoother cornering.

Key Features

• Authentic electric small-scale R/C car designed for indoor driving and close-quarters racing.
• Readyset package ships with a fully assembled chassis, painted body, and transmitter for minimal setup.

• Pinion gears included: 6T, 7T, 8T, 9T for quick gearing changes.
• Spare nuts supplied to speed repairs after wheel or gear work.
• Wheel wrench included for fast tire and wheel changes.
• Pinion gear tool included to make gear swaps simple and precise.
• Tires and wheels installed and ready for driving.
• AAA-size alkaline batteries x 4 required for the chassis operation.
• AAA-size alkaline batteries x 4 or Ni-MH batteries x 4 required for the transmitter.

Notes & Design Details

• The Audi R8 LMS Phoenix Racing NBR 2010 #98 livery reproduces the blue and yellow Bilstein paint scheme from the Nürburgring 24-hour race.
• MR-04 lowers the center of gravity compared with the MR-03 for improved cornering and straight-line stability.
• New front knuckles with integrated kingpins reduce scrub by 1.5 mm per side for more linear steering.
• 3 mm inner-diameter ball bearings reduce rotational resistance in the drivetrain.
• Front suspension geometry aligns camber with upper-arm movement to keep optimal tire contact while cornering; revised caster angle sharpens steering response.
• Batteries sit lower in the chassis than the MR-03 layout to improve handling balance.
• Rear uses a coil-spring damper for impact cushioning; you can upgrade to optional oil-filled shocks for finer damping control.
• T-bar rear suspension plate provides controlled flex for consistent rear-end behavior; optional FRP and carbon parts are available for rigidity changes.
• All axles use the same size low-resistance ball bearings to simplify spares and maintenance.
• Front tread can be adjusted using the supplied parts set; rear tread is changeable via wheel offset when fitting other bodies.
• The Syncro KT-531P transmitter offers steering and throttle trims, dual rate adjustment for steering angle, and a default training mode to limit top speed.
• The separately sold LED light unit set (MZW429R) cannot be installed on this Audi R8 LMS body.
