Overview

Racetech USA Alloy Back Brackets

Racetech USA alloy back brackets are high-strength, lightweight 5mm or 6mm aluminum seat supports designed to bridge the gap between a racing seat's shoulder beam and the vehicle's roll cage. They improve safety and driver feedback by reducing seat flex under high-load cornering or braking. These brackets are often required for FIA-homologated installations.

Additional details:

* These brackets secure the rear of the seat to the roll bar, enhancing structural rigidity and improving driver feel
* Manufactured from 5083-grade aluminum alloy, providing a balance of high strength, low weight, and corrosion resistance
* Common models:
-- RTB1006B/RTB1006BW (Standard/Wide): 6mm thick, often used for 129 Series seats to meet FIA 8862-2009 standards.
-- RTB2115B: A 5mm bracket designed for 119 and 4100 Series seats
-- RTB3115B (Adjustable): A 2-piece, 5mm adjustable bracket for versatile installation
Installation: The brackets require attachment to the shoulder beam of the seat and are typically used with cage clamps to fix to lateral/diagonal roll cage tubes
* These brackets are essential for professional motorsports, ensuring the seat remains a structural part of the chassis for maximum safety
