A New Era for GP Touring Car Racing! At the initial stage of suspension movement, a soft, supple spring is ideal. However, in high-speed corners, a soft spring may not provide enough support under heavy loads. On the other hand, a stiffer spring designed to handle these high loads can be too stiff during the initial stage of suspension movement. Finding the ideal spring for different circuits and track conditions has always been a challenge, often requiring considerable time and effort to achieve the right setup. Our new Progressive Springs solve this problem! By combining closely wound and widely spaced coils, these springs provide different levels of support throughout the suspension travel, delivering the ideal balance between initial softness and support under heavy loads. Developed by SMJ's spring specialist, Masayuki Miura, this versatile lineup offers options optimized for each racing category.

Precision machined from lightweight, high grade pure titainium. This delivers a smoother driving feel than the standard aluminum version offered in the kit. Making better use of the materials properties. The surface has been anodised to give a vibrant finish.
Due to the nature of the anodizing process applied to the surface, there may be slight variations in the actual color, but this does not affect the performance of the parts.

The MSX1 Major features:

Height-Adjustable Front & Rear Gearboxes

The MSX1 features height-adjustable front and rear gearboxes, allowing the differential position to be adjusted to three different heights. This provides racers with additional tuning options to alter the buggy’s handling characteristics and optimize performance for different track conditions.

Slipper Clutch & Adjustable Front One-Way

A slipper clutch provides an additional tuning option for managing power delivery, while the adjustable front one-way allows racers to fine-tune the drivetrain characteristics to match their preferred driving style and track conditions.

2.5mm A7075 (T6) Aluminum Chassis

The MSX1 utilizes a lightweight and durable 2.5mm A7075 (T6) aluminum chassis featuring an 8-degree kick-up. The chassis design provides a strong foundation for the buggy while helping deliver predictable handling and stability.

7-Degree Aluminum Caster Blocks  

Durable 7-degree aluminum caster blocks provide precise front-end geometry and contribute to the MSX1’s responsive and consistent handling.

Lightweight Lexan Body  

The MSX1 comes equipped with a lightweight, stylish Lexan body designed to complement the buggy’s modern appearance while helping reduce unnecessary weight.  

Designed for Performance and Adjustability  

With its combination of extensive tuning options, durable construction, and proven Mugen Seiki engineering, the MSX1 is designed to give racers the tools they need to maximize performance on the track.  

The MSX1 represents an exciting new addition to the Mugen Seiki lineup, offering racers a modern platform with the adjustability and performance expected from Mugen Seiki.
