An OMP direct fit subframe for the BMW Mini R56. Part number HC818-R56.
This is the frame for a fixed back bucket on a harness. It sits the seat lower than the Sparco R56 frame and has no bracket for the original seatbelt buckle, so plan on a harness, with a roll cage or harness bar behind the seat. If you are keeping the factory seatbelts, the Sparco R56 frame comes with a metal bracket for the buckle.
Check the chassis code, not the Mini badge
The R50, R52, R53 and R56 span two Mini generations and they do not all take the same frame. The R53 is listed separately on the same HC818 stem.
This is the commonest cause of a wrong order on a Mini. The cars look closely related and the floors are not, so read the V5 rather than the badge, and send it to us if the code is not obvious.
What a Mini needs from a seat
Support more than height. A Mini already puts you fairly low and quite upright, so the gain from a bucket is mostly lateral: these cars carry a lot of cornering speed for their size and the standard seat lets you move.
Space is the constraint. A Mini cabin is narrower than the exterior suggests, so measure between the tunnel and the sill before choosing a shell and tell us the figure.
The frame
Steel, base mount, bolting to the mounting points already in the floor. Nothing is drilled and the standard seats come out whole, which matters on a car people tend to sell on rather than keep.
Two bolt patterns from the multi-hole clusters at each corner: 345mm by 271mm for Sparco, OMP and Corbeau, 405mm by 290mm for Recaro. Sold singly and handed, so order twice for a pair.
