Disclaimers:
- Seats come in many different shapes and sizes, so not all seats will fit in all vehicles. It is up to the end user to determine if the seat will fit before ordering the seat bracket and other components.
- Many vehicles have the steering wheel offset toward the center of the vehicle. This can be accentuated when installing an aftermarket seat of a different size than the factory seat.
- Replacing a factory seat with an aftermarket seat may cause the vehicle's warning indicators to activate. This can be due to airbag, weight and/or other sensors in the factory seat that are not included in an aftermarket seat. It may be possible to eliminate these indicators with an electronic resistor, but it is up to the end user to determine if a resistor will work and which resistor to use.
- Professional installation is recommended.
Putting a modern seat into a 1970-1974 Pontiac Firebird is one of the best upgrades for a vintage build, but the original floor was never designed to carry one. Fabricated mounts rarely end up square, and they're hard to undo. A vehicle-specific bracket solves both problems.
Every Sparco 600 Series base is built for a specific vehicle and bolts straight to the factory seat mounting points. It turns an uneven factory floor into a flat, solid platform for your seat, and the install is fully bolt-in.
It's built from 3/16" steel for stiffness and finished in black wrinkle powder coat. The Sparco top plate is drilled for Sparco sliders. There's also a wide platform for direct side-mount installation (drilling required), which drops the seat as low as possible in a race car.
This is the driver/left base, sold individually. The passenger side is 600SB220R. Confirm your seat's dimensions against the cabin before ordering. Removing the factory seat can trigger airbag or occupancy warning lights, which may need a resistor. Professional installation is recommended.
