More info
This Kyosho MINI-Z RWD readyset pairs the current MR-04 chassis with a fully finished DENSO KOBELCO SC430 2012 body, so there's no building or painting standing between you and your first run. The chassis arrives factory assembled, the body comes pre-painted with markings already applied, and the included Syncro KT-531P transmitter rounds out a package that only needs batteries to get moving. That's the appeal of a Kyosho readyset: less setup friction before the first run, more time actually driving.
The MR-04 replaces the older MR-03 platform that ran in previous MINI-Z readysets, and the changes go beyond a name update. New front knuckles with integrated kingpins cut scrub by 1.5mm on each side versus the MR-03, and 3mm inner diameter ball bearings reduce rotational resistance in the front end for a more linear feel through the steering. The four AAA batteries that power the chassis sit lower in the MR-04 than they did in the MR-03, which drops the car's center of gravity and helps with both cornering stability and straight-line tracking. Front suspension geometry adjusts camber angle as the upper arm moves, keeping tire contact more consistent through a corner, and revised caster angle sharpens steering response.
Key Features
- Factory-assembled MR-04 chassis, the fourth-generation platform that debuted in the EVO2 model
- Pre-painted DENSO KOBELCO SC430 2012 body finished to display-model standard, decals already applied
- Geared differential for smooth cornering behavior
- Full ball bearing setup on all axles, with matching front and rear bearing sizes
- Syncro KT-531P pistol-grip transmitter with a steering wheel styled after a real car's wheel
- Rear suspension uses a coil spring damper, upgradeable later to an optional oil-filled shock
- T-bar rear suspension plate holds the motor and rear axle as one flexible assembly
- Compatible with the wider range of MINI-Z Racer optional parts for those who want to tune further
- Optional gyro unit (MZW711) can be added, with sensitivity adjustable from a volume dial on the chassis
The transmitter itself deserves a mention beyond just being included. The KT-531P lets you trim the neutral position of steering and throttle, adjust steering angle through dual-rate settings, and even drop into a reduced-speed training mode, which is actually the default setting out of the box. That's a nice touch for anyone new to RC cars or just getting used to MINI-Z scale handling before opening things up.

Kyosho also built in some practical flexibility. If you swap to a different body down the line, a front tread adjustment parts set is on hand to match the new body's width, and rear tread can be changed simply by swapping wheel offset. The kit also comes with pinion gears in 6T, 7T, 8T, and 9T sizes, giving you room to adjust gearing without buying extra parts right away. A wheel wrench, pinion gear tool, and spare nuts round out the small tool kit included with the car.
Why Choose This Product
If you want to get into MINI-Z racing without hunting down a chassis, body, and transmitter separately, this readyset covers all three in one box, already matched and ready to run. The MR-04 platform is the current standard chassis Kyosho uses across its higher-end MINI-Z RWD lineup, so you're not starting on outdated hardware, and the SC430 livery is finished to display quality if you just want it to look sharp sitting on a shelf between runs. Note that a motor case and differential gear assembly suited to the body are required separately if you plan to switch to a different MINI-Z body down the road.
