The BMW Series 1 E87 is a five-door hatchback that makes a popular track day and club racing base, and OMP’s HC848-X2 covers both seat positions in one order. This is a pair of vehicle-specific subframes, one for the driver side and one for the passenger side in right-hand drive.
Each frame is steel, powder-coated black, and designed to drop into the E87’s factory floor mounting points in place of the standard seat runners. No drilling is needed. The standard runners come out, the subframe goes in, and the replacement seat mounts on top, either direct to the frame or on side mounts if you are using a fixed-back competition seat.
OMP’s HC848 carries two bolt patterns: 345mm x 271mm (the OMP and Sparco standard) and 405mm x 290mm (the Recaro standard). That means you have a choice across four seat brands without buying a second frame: Corbeau, OMP, Recaro, and Sparco base-mount seats are all compatible.
Buying the pair covers driver and passenger in one order. If you only need the driver seat, single subframes are available for many other models in the OMP range, but the E87 pair listing (HC848-X2) covers both positions and keeps the order simple.
Before ordering, confirm which seat you are fitting, because the bracket between the subframe and seat varies by seat model. If you are ordering the frame before the seat is decided, let us know and we will check the requirements when you are ready.
