Step-by-Step Installation Guide
- Remove the Old Seat
Begin by identifying the bolts that secure your current seat to the floorpan. Most vehicles use four mounting points—two at the front and two at the rear of the seat base. Before attempting removal, slide the seat all the way back to gain access to the front bolts, which are often tucked under the front edge of the seat when in the normal driving position.
Using a socket wrench or ratchet tool, carefully loosen each bolt. It's common for these fasteners to be tight due to years of corrosion or thread-locking compound. Apply penetrating oil if necessary and allow it time to work before continuing. Once the front bolts are loose, slide the seat forward to access the rear mounting points and remove them as well.
If your vehicle has integrated seat belts (common in sportier models), you'll need to disconnect the wiring harness for the belt warning system. These are usually located beneath the seat and feature a quick-disconnect plug. If your car uses floor-mounted seat belts instead, simply move the belts out of your way without disconnecting them.
- Use a socket wrench or ratchet set (typically 10mm to 14mm sockets)
- Penetrating oil may help loosen corroded bolts
- Label all hardware for easy reassembly later
- Prepare the New Seat
Before installing your new white racing seat, inspect it thoroughly for any damage incurred during shipping. Check that all mounting brackets and hardware are included according to the manufacturer's instructions. Racing seats typically come with either fixed rails or require separate rail kits depending on your application.

Many aftermarket racing seats comply with safety standards such as FIA homologation, so ensure your chosen harness meets local legal requirements for street use if applicable.
Racing seats sit lower than standard factory seats, which affects your driving position. Sit in the seat while it's on the ground to check visibility over the steering wheel and reach to the pedals. Adjust the rail positioning or consider spacers if needed to achieve optimal ergonomics.
- Verify seat height matches your driving preferences
- Check compatibility between seat rails and your vehicle's floorpan
- Ensure all included hardware is appropriate for your installation
- Install the New Seat
Begin by extending the seat rails fully and attaching them to the underside of your racing seat using the provided bolts. These connections should be tightened securely but not overtightened to avoid damaging the seat frame. Once the rails are attached, compress them by sliding the seat backward until they lock into their retracted position.
Position the seat inside the vehicle, aligning the rail mounting holes with the existing floor holes. Insert the bolts from underneath (if possible) to prevent them from dropping into the car body. Use a torque wrench if available to tighten fasteners to the manufacturer's specifications—usually around 25-30 ft-lbs for steel-to-steel connections.
If your racing seat includes a harness system, connect it to the vehicle's existing buckle or install a new mounting point if required. Ensure all straps have proper tension and there is no twisting in the webbing. Perform a final inspection by pushing firmly on different parts of the seat to confirm there's absolutely no movement.
- Double-check all mounting bolts after initial test seating
- Verify seatbelt function and locking mechanism operation
- Ensure full range of motion for adjustable rails if installed
