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 E92 3-Series, 2007 onward. Part number SM-E92-S1.
The E92 mount is the basis for several others in the PCI range, including the M2 and F22 parts, which is what you would expect from cars sharing a floor arrangement. If you have seen this working in a related BMW, it is the same idea.
The slider
This is the slider version, so the seat moves fore and aft after fitting. PCI’s S1 slider bolts to the base with four bolts rather than the two a conventional slider uses, which they describe as twice as strong as two bolt mounting. With a harness loading the seat that is the right side to be on.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, with the bends placed to add stiffness rather than using thicker metal everywhere. Gloss black powder coat, grade 10.9 8mm hardware, and five and six point sub belt mounting locations built into the mount, which saves fabricating a crotch strap anchor.
Fitment and ordering
Side mount, for a competition bucket. It bolts to the factory seat mounting points, so nothing is drilled and the original seats come out whole and can go back in.
Handed, so choose driver or passenger side and order twice for a pair, or take the pair listing.
