A PCI Racing adjustable seat mount for the Subaru WRX and STI, 2015 onward. Part number SM-15WRX-A1.
PCI’s adjustable mount gives the largest range of adjustment and the lowest possible seat fitment in their range, and it does that by leaving out the slider.
Whether that suits a WRX depends on how the car is used. For stage events with a co-driver, or a car shared between drivers, the sliding sub frame is the better buy because the seat has to be reset regularly. For a circuit car with one driver, this sits lower and costs less.
Not permanent
The hardware interlocks into the slots in the seat base, so the position can be changed later with one tool without removing the mount from the car.
Construction
Laser cut and CNC formed from one piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, and five and six point sub belt mounting locations built in. Those sub belt locations save fabricating a crotch strap anchor, which on a six point installation is usually the awkward part.
Ordering
Side mount, for a competition bucket, on the factory seat mounting points so nothing is drilled.
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 Subaru Impreza WRX/STI, including our fitting guide, and Installing Sparco Racing Seats In a Subaru WRX – What We Learned. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is made for the Subaru WRX STI. Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, 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.
