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 F80 M3. Part number SM-E92-S1-F80 M3.
Derived from the E92 mount, which follows from the two cars sharing their floor arrangement.
Keep the originals
On an F80 M3 the factory seats are worth serious money, particularly the buckets. This mount bolts to the factory seat mounting points, so they come out whole and go back in when the car is sold. Nothing else you do to an M3 is as easy to undo, and it is worth doing properly.
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. With a six point harness loading the seat rather than a seatbelt, that is where you want to be.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, with bends placed to add stiffness rather than using thicker metal throughout. Gloss black powder coat, grade 10.9 8mm hardware, and five and six point sub belt mounting locations built into the mount.
Ordering
Side mount, for a competition bucket. Handed, order twice for a pair.
Tell us about side airbags in the factory seats. On an F80 they are fitted, and removing one has consequences for the car’s systems worth understanding first.
