A Planted Technology seat bracket for the Chevrolet Corvette on the C5 chassis, 1997 to 2004. Part number SB198.
The C5 is where the Corvette got a rear transaxle and a hydroformed chassis, and it is the generation that turned the car into a proper circuit machine rather than a straight line one. C5s are cheap now and quick enough to be worth building, which is why they turn up with competition seats far more often than a car of that value normally would.

The C6 and C7 bracket carries a specific note about the seat belt tab being on the inboard side only, and the ZR1 bracket carries a stronger warning still. Belt arrangement is not something to assume carries over between Corvette generations. Photograph your seat area with the carpet back and send it to us before you order.
Getting in and out
A C5 has wide sills and a low roof. A fixed shell changes how you get into the car considerably, and on a road car that is worth thinking about honestly before you commit. Tell us how the car is used.
Handed. Tell us about side airbags in the factory seats too.
Have you written anything about this exact product?
Yes, we have covered this exact product: Planted Technology Chevrolet 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 Chevrolet Corvette [C5 Chassis] (1997-2004). 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.
