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.
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.
