A PCI Racing sliding sub frame for the Acura RSX, 2001 to 2006. Part number SM-DC5-S1.
The part number is the useful detail. DC5 is the chassis code, and the Acura RSX is the same car as the Honda Integra DC5 sold under a different badge in North America. If you have an Integra DC5 rather than an RSX, this is your mount.
The slider
The seat moves fore and aft after installation, which suits a car that is shared or 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.
If you want the lowest possible fitment, the DC5 adjustable mount sits lower and costs less. In a car where Honda put the driver high, that is a real consideration.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, with the 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 in.
Ordering
Side mount, for a competition bucket, bolting to the factory seat mounting points so nothing is drilled.
Handed, order twice for a pair. If the car has its factory Recaros, keep them: DC5 values are climbing and this installation is reversible.
Have you written anything about this exact product?
Yes, we have covered this exact product: PCI Racing Sliding Sub Frames Updated For 2023. 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.
