Press Release From JConcepts:

Born on the world stage, ready for a new generation. JConcepts brings the Finnisher to the Team Associated RB10, capturing the look, attitude, and racing heritage of the original in a body designed specifically for today’s retro-inspired buggy. It’s a resto-mod approach with a familiar JConcepts signature—competition styling from a memorable era, fitted to a platform ready to create new memories.

The Finnisher story began in Vaasa, Finland, where JConcepts arrived at the IFMAR World Championships with an all-new body design. Its name paid tribute to the location, while its distinctive shape made an immediate impression on the track. Building on lessons learned from the Punisher body line, the Finnisher combined a more aggressive appearance with carefully considered details for handling on the ground and control in the air.

Originally developed around the extended +8mm Team Associated B4.1 chassis, the Finnisher reflected the demands of increasingly technical racetracks. Bigger jumps, faster corners, and changing conditions called for attention to every surface. The increased windshield angle, forward cab position, simplified side-pods, and close chassis fit each played a role in the original design’s approach to airflow, steering response, and jumping consistency.

That unmistakable design language provides the inspiration for the RB10 edition. The forward cab profile and angled windshield establish the Finnisher’s recognizable stance, while the chamfered side-pod treatment carries the clean, purposeful appearance along the chassis. The stepped area behind the cab and distinctive window styling recall the details that gave the original its identity. Together, these elements bring the vibe and feel of the World Championship-era Finnisher to the RB10 with a fit developed specifically for the vehicle.

Completing the package, the Aero 6.5” wing complements the Finnisher’s aggressive profile and brings another familiar JConcepts racing element to the RB10. From the forward cab to the rear wing, the combination captures the competition-inspired appearance that makes this resto-mod project feel complete. For enthusiasts building a retro-inspired RB10, the Finnisher brings that history into the paint booth and onto the track. Revisit a favorite racing scheme or create something entirely your own; the familiar lines provide the canvas for a fresh take on a JConcepts classic.
