Brey Krause R-9246 Driver Seat Bottom Mount Adapter - BMW E46/E85/E86

The Brey Krause R-9246 Seat Mount is an innovative solution that attaches bottom mounting Sparco, Cobra or Recaro seats to the OE-factory, power slider mechanisms on BMW E46 (including M-Series), and E85/E86 (Z4 Roadster/Coupe) cars. The mount maintains the factory power adjustment for both the seat height and front/back settings (requires BMW E30 window switches - not included, but easily sourced).
