Brey Krause R-9292 Bottom Seat Mount Adapter - BMW E9x/F8x

The Brey Krause R-9292 Seat Mount is an innovative solution that attaches bottom mounting Sparco, Cobra or Recaro seats to the OE-factory, power slider mechanisms on BMW E9X, F3X, E82, & F8X Series cars. The mount maintains the factory power adjustment for front/back settings (requires BMW E30 window switches - not included, but easily sourced).
