Rear Offset Kit Mugen MBX8R Ultimate

Take your Mugen MBX8R performance to the next level with the new Rear Offset Kit from Ultimate Racing! Specifically designed to optimize rear geometry, this kit introduces a trend successfully adopted by leading official brands in today?s market.

With this kit, you'll achieve greater overall grip in the rear end thanks to the increased offset, resulting in an immediate boost in your car's mechanical grip.

Why do you need it in your toolbox?

Predictable driving: The stock MBX8R tends to dive sharply at the rear when track conditions change or when the tire choice isn?t ideal. This kit allows the rear bridge to work flatter and twist less during acceleration.

Crisis-proof in races: Minimizes time loss in those heats where the track becomes slippery or you miss the perfect tire. The car will be much more forgiving and maintain a noble behavior.

Recommended Setup Guide

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

Rear stabilizer bar: If you?re using the 2.7 bar stock, it?s recommended to switch to a 2.6 bar as a base. If the track grip is extremely low, don?t hesitate to reduce the thickness even further.

Rear upper link: You should shorten it by 3 mm from your usual measurement (for example, if the distance between plastics was 19 mm, set it now to 16 mm).

Rear knuckle position: The stock car usually uses the upper hole of the knuckle. When mounting this kit on medium or high grip tracks, it?s highly recommended to use the lower hole. This will further flatten the rear end while providing you with extra rotation in corners.
