Brey Krause Side Mount Brackets for seats 410mm-434mm to fit in BMW E9X/E82 Series

Description

BMW E9X / E82 Fixed-Back Bucket Seat Mount – R-9261 (410–434mm)

The R-9261 Seat Mount is a purpose-built, lightweight, and ultra-strong solution for installing fixed-back bucket seats directly to the floor of BMW E9X (E90, E91, E92, E93) and E82 chassis. Designed for precision fitment rather than generic slot-style adapters, the R-926X line delivers lower seating position, reduced weight, and OEM-level mounting integrity—ideal for track, race, and performance-focused street builds.

Constructed from 11-gauge Type 304 stainless steel and finished in a durable black wrinkle powder coat, this mount provides exceptional strength, corrosion resistance, and long-term durability under motorsport conditions.
