Complete fitting kit: side mounts included. This frame comes with its own side mounts, so any side mount bucket seat bolts straight to it. You only need the seat and the frame, with no separate side mounts to buy. The slider is built in as well, so no separate runner kit is needed.
Belt buckle clip included. This frame comes with a belt buckle clip, suitable for attaching a harness or the car’s factory seatbelt clip.
A PCI Racing sliding sub frame for the BMW F87. Part number SM-E92-S1-F22-1.
The F87 is the M2, and the part number tells you it shares its design with the F22 mount, which in turn derives from the E92. That family of BMWs shares enough of its floor arrangement for one design to serve them all.
Why an F87 gets seated
Usually the harness. A factory seat is built around a three point belt, and once you move to a four or six point the shoulder slot position and the shell shape start to matter a great deal. The seat is what makes a harness work rather than the other way round.
The slider
The seat moves fore and aft after installation. PCI’s S1 slider bolts to the base with four bolts where a conventional slider uses two, which they rate as twice as strong as two bolt mounting.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, five and six point sub belt mounting locations built in.
Ordering
Side mount, for a competition bucket, on the factory seat mounting points. The standard M2 seats come out whole and go back in at sale time, which on this car is worth money.
Handed, order twice for a pair. Tell us about side airbags before anything comes out.
