Planted Technologies

The best seat bases for a 2013+ Subaru BRZ, 2013-2016 Scion FR-S, or 2017+ Toyota 86 at JDMuscle are the two Planted Technologies bases in this collection: one for the driver side and one for the passenger side of that same platform. A seat base is the foundation an aftermarket seat mounts to, so choosing the side-specific base for your car is the starting point of any seat swap. Check your year and model, and confirm which side you need.

A seat base, sometimes called a seat bracket, bolts to the floor of the car and gives an aftermarket seat a flat, correctly positioned mounting surface. Factory seats use integrated mounting, so replacing them with a fixed-back or reclining aftermarket seat normally requires a vehicle-specific base, plus sliders or side mounts depending on the seat. The important checks are side (driver and passenger bases are not interchangeable), floor bolt pattern for your exact chassis, and how the seat and hardware you plan to use attach to the base. Start your shopping in Seats and Harnesses.

Planted Technologies is represented here by exactly two focused listings: the driver-side seat base and the passenger-side seat base for the FR-S, BRZ, and 86. The brand's approach in this collection is vehicle-specific fitment rather than a universal bracket, which matters because floor shapes and bolt positions differ between cars. Buying the base made for this platform avoids the cutting and adapting a universal bracket can require.

Sparco is one of the seats most often paired with a base like this, known for fixed-back and reclining seats used in track and street builds. If you are choosing the seat before the base, Sparco's range shows the shell styles and sizes the base will need to support. Match the seat's mounting style to the base before ordering either part.

Corbeau is another seat maker BRZ and 86 owners cross-shop, with reclining and fixed-back seats aimed at street and dual-purpose cars. Corbeau is a useful comparison for seating position and bolstering, and its seats likewise need a vehicle-specific base underneath.

Do I need a seat base to install an aftermarket seat?

In most cases, yes. An aftermarket seat needs a base that bolts to your car's floor and presents the correct mounting points for the seat, sliders, or side mounts. Check the seat maker's requirements for your exact seat before ordering.

Are driver and passenger seat bases the same?

No. The two listings in this collection are side-specific, and floor shapes and mounting points can differ by side. Order the driver base for the driver seat and the passenger base for the passenger seat.

Will these bases fit my car?

These bases are listed for the Scion FR-S 2013-2016, Subaru BRZ 2013+, and Toyota 86 2017+. Later GR86 and newer BRZ cars are a different platform, so check your year and model carefully before ordering.

How difficult is a seat base installation?

Swapping a base is unbolting the factory seat and bolting the new assembly in, but seat hardware is safety-related, so torque fasteners correctly and keep the work methodical. If you are unsure about any step, have a shop complete the install.
