A Planted Technology seat bracket for the Chevrolet Camaro and Pontiac Firebird Trans Am, 1993 to 2002. Part number SB059.
From 1993 the two cars share a bracket, which they did not do in the previous generation. General Motors brought the seat mounting into line when they redesigned the F-body.
The LS1 cars
From 1998 these got the LS1, which is the engine that made the fourth generation genuinely quick and which is still the default cheap route to serious power. A 1998 onwards car is a different proposition from a 1993 LT1 car, and it is where most of the building happens.
The T-top question
A great many of these have removable roof panels. That affects headroom differently from a fixed roof car and it affects how much water gets in when the panels are off or leaking, which they do. If yours is a T-top, tell us and we will talk about trim as well as height.
Practical
Side airbags on later cars, not on early ones. Tell us the year.
Handed, so order twice for a pair.
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 Camaro/Pontiac Transam (1993-2002). 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.
