Take your Mugen MBX8R's performance to the next level with the new Ultimate Racing Rear Offset Kit! Specifically designed to optimize rear geometry, this pack introduces a setup trend successfully adopted by the industry's leading factory teams.

This kit provides increased overall rear traction by expanding the offset, resulting in an immediate boost to your car's mechanical grip.

Why do you need it in your pit bag?

Predictable Handling: The stock MBX8R tends to squat sharply at the rear when track conditions change or tyre choice isn't optimal. This kit ensures the rear suspension stays flatter and flexes less under acceleration.
Race Insurance: It minimizes time loss during those qualifiers where the track becomes slick or your tyre choice isn't perfect. The car becomes much more forgiving and maintains noble driving characteristics.

Kit Includes
1 x Ultimate C-Plate +2mm
1 x Ultimate D-Plate +2mm
1 x Ultimate Wheel Hex Set +5mm
1 x Ultimate Wheel Hex Set +4mm
2 x MUGEN 89mm Driveshafts
1 x MUGEN MBX8 Rear Suspension Arms

⚠️ Assembly Note: To install this kit, you only need to slightly shave the included rear suspension arm in the contact area to prevent any rubbing against the diff cup outdrive. See picture 6.

Recommended Setup Guide

To get the most out of this new geometry, we suggest the following adjustments compared to your stock setup:

Rear Anti-Roll Bar: If you normally run the stock 2.7 bar, it is recommended to switch to a 2.6 bar as a baseline. If track grip is extremely low, do not hesitate to go even softer.

Rear Upper Link: You must shorten it by 3mm compared to your standard measurement (e.g., if the distance between plastics was 19mm, set it to 16mm).

Rear Hub Position: The stock car typically uses the upper hole on the rear hub. Once this kit is installed on medium to high-grip tracks, it is highly recommended to use the lower hole. This will keep the rear end even flatter while providing extra rotation mid-corner.
