CMS Performance Sub Strap + Lap Belt Mount for BMW
This mount fits BMW cars (2010+), driver or passenger side
The Best Way to Mount Harness Lap and Sub Belts in Your BMW
The CMS Performance Sub Strap + Lap Belt Mount is designed to be installed and used with your factory BMW seats, giving you strong, secure mounting points for your racing harness lap- and sub-belts without any drilling or cutting. The CMS Performance mount bolts to the rear mounting points of the driver and/or passenger seat, beneath the seat slider tracks, using your original BMW mounting bolts.
CNC machined from 1/4-inch solid carbon steel and fully 360º TIG welded, the CMS Performance Sub Strap + Lap Belt Mount provides an extremely strong structure to which you can clip or bolt your harness lap belts and wrap your sub strap(s). Powder coated a rich, durable satin black, the CMS Performance Sub Strap + Lap Belt Mount is nearly invisible once installed. It does not interfere with seat movement fore/aft or up/down in any way, installs in minutes, and can be removed just as easily without leaving a trace.
The CMS Performance Sub Strap + Lap Belt Mount is designed, manufactured, and powder-coated entirely in-house in the USA.
