A Planted Technology seat bracket for the Volvo S40, first generation, 1995 to 2004. Part number SB355.
The first S40 and V40 were built at the NedCar plant in the Netherlands alongside the Mitsubishi Carisma, and the two share a great deal underneath. If you have a Carisma, or a V40 estate of the same years, send us the registration and we will check whether this suits it.
The T4
The turbocharged T4 is the one worth building. It was quick for what it was and it had a following in touring car racing, which is where the interest in seating one comes from. The naturally aspirated cars are ordinary transport.
What Volvo built into the seat
Volvo of this era put a great deal of engineering into seat structures, including whiplash protection systems that are part of the seat rather than bolted to it. That is worth understanding before you remove one, and it is worth being honest that a competition shell does not replace it. On a car that stays on the road, think about that.
Practical
Twenty five to thirty years old. Get the carpet up and check the metal round the mounting points before you spend.
Handed, so order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Planted Technology Volvo Sub-Frames: Ready For The 2025 Racing Season. 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 Volvo S40 [First Generation] (1995-2004). 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 Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
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.
