About the MR-04


Advanced MR-04 Chassis for Improved Handling

The MR-04 chassis introduces multiple upgrades over its MR-03 predecessor, including a lower center of gravity and improved steering geometry. These enhancements provide sharper, more predictable handling and better cornering stability, essential for on-road racing. The W-MM (wide, mid-motor) configuration also gives users greater tuning potential, making it easier to optimize performance for different track layouts.

Ready for Customization

Ideal for drivers who want to create a one-of-a-kind Mini-Z, this set is fully compatible with Kyosho’s extensive range of Auto Scale Collection bodies and unpainted white kits. You can paint your body to match a real car or your own racing colors. This level of customization makes it perfect for both casual racers and competitive drivers who demand a personalized RC experience.

Reliable KT-531P Transmitter and Balanced Motor Power

Included in the set is the KT-531P pistol-grip transmitter, a user-friendly and reliable controller that makes the Mini-Z feel like a full-sized race car. The 130-class MZ9PB motor delivers balanced power suitable for both beginners and experienced racers.

Works great, easy to assemble.
Size: 2 Tier-9.5''Wx10.5''Dx9.5''H
I bought this to try and contain our cabinet clutter. It works really well. Was easy to assemble. I use it on the countertop instead of inside of the cabinets. Looks nice enough to sit out. Will buy 1 more in the coming days. The storage areas pull out, makes for easy access.

Awesome Spice Rack!
Size: 2 Tier-13.5''Wx10.5''Dx9.5''H
This works perfectly. I bought two as I have a lot of spices. Do need to remember that the height needed for unit is 9 inches, but with full size spice jars on top rack, you need at least 11 inches. Otherwise it works great. Smooth movement of the drawers. Very sturdy and stable.

A good value, works well.
Size: 1 Tier-8.5''Wx10.5''Dx2.5''H, Size: 1 Tier-8.5''Wx10.5''Dx2.5''H
It works great, and a good value for the price. Super easy to install, comes with a template (you probably wont need), screws and a screw driver. Easy peasy It will not affect the performance, but it is a little flimsy. Great service and price. Quality packaged as well.

Great quality product
Size: 2 Tier-5.5''Wx10.5''Dx9.5''H
The product quality is great. Assembly is needed but relatively easy. The moving shelves have a premium slide and catch at the end. I was impressed by this the most. The only potential small issue were the inside protectors it came with. Not that they're poor quality, they have a decent thickness. But during assembly they kept falling out easily because there wasn't enough catch on the shelf itself. In actual stationary use, this may not be an issue. But would have been better if the shelf held onto them more. You may not notice it when you put things on the shelf on top if it but they're also not a great color/texture match. Semi-opaque white plastic on a black metal rack; it cheapens the product. And in case you were wondering, magnets can stick to it. Overall though, I am pleased with the quality of this product.
