A PCI Racing sliding sub frame for the BMW 1-Series, 2008 to 2011. Part number PCI-BMW-1-Series.
Rear wheel drive, cheap to buy now, and light enough to be worth building, which is why 1-Series cars turn up at track days far more than a family hatchback normally would.
Check the body style and year
BMW used several body styles across this generation and the years matter. Send us the registration if you are at all unsure, and we will confirm the mount is cut for your car before anything ships.
The slider
The seat moves fore and aft after installation, which suits a car that is still used on the road. 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, with five and six point sub belt mounting locations built into the mount.
Ordering
Side mount, for a competition bucket, bolting to the factory seat mounting points so nothing is drilled and the original seats come out whole.
Handed, order twice for a pair. Tell us about side airbags in the factory seats before anything comes out.
Have you written anything about this exact product?
Yes, we have covered this exact product: Top 5 reclining seat choices for your BMW 1-Series, including our fitting guide. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on PCI frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Base mount or side mount, and does it matter?
This is a side-mount frame: the seat hangs between side brackets bolted through its flanks, the motorsport-style stack that gives fine height and angle control. Our guide on base mount versus side mount explains the whole fitting stack.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
