A PCI Racing sliding sub frame for the Subaru BRZ, 2013. Part number SM-FRS-S1.
The part number gives the game away: FRS is the Scion FR-S, which is the same car as the BRZ and the GT86 sold under a third badge. The mount fits all three of that generation, so if you have seen it working in a GT86 it works here.
The slider
The seat moves fore and aft after fitting, which suits a car that is still driven on the road. PCI’s S1 slider bolts to the base with four bolts where a conventional slider uses two, and PCI rate that as twice as strong as two bolt mounting. With a harness loading the seat rather than a seatbelt, that is the right side to be on.
If you want the lowest possible fitment and never need to move the seat, PCI’s adjustable mount for this car sits lower and costs less. Ask us.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, with bends adding stiffness where thicker metal would otherwise be needed. Gloss black powder coat, grade 10.9 8mm hardware, 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 standard seats come out whole. Handed, order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Customer Question: How Do I Fit The Sparco R100 Seat Into My Subaru BRZ?, and PCI Racing Sliding Sub Frames Updated For 2023. Some of that comes straight from real customer questions, so you are reading answers other buyers actually needed.
Will this fit my car?
This frame is made for the Subaru BRZ. 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.
