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 E36 3-Series, 1992 to 1998. Part number SM-E36-S1.
E36s are cheap enough to build properly and old enough that the standard seats are usually past their best, which is why so many end up with a bucket in them.
Why a proper mount on a car this age
A fabricated bracket on a thirty year old floorpan is exactly the wrong combination. A purpose made mount bolts to the factory seat mounting points and feeds seat load into structure designed to carry it. On a car of this age it is worth lifting the carpet and looking at the metal round those points before you spend anything, because a mount can only do its job if what it bolts to is sound.
The slider
PCI’s S1 slider bolts to the base with four bolts where a conventional slider uses two, which PCI rate as twice as strong as two bolt mounting. The seat moves fore and aft after fitting, which suits a car that is shared or still used on the road.
Construction
Laser cut and CNC formed from one piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, with five and six point sub belt mounting locations built in.
Ordering
Side mount, for a competition bucket. Handed, so order twice for a pair.
