The Planted Steel 90 Degree Universal Side Mount in black. Part number PS90SM-B.
Side mounts are the pieces between the seat and the floor bracket. The 90 degree profile means the seat bolts through its side holes into a vertical face, which is the arrangement most competition seats are designed around.
Steel or aluminium
We also stock an aluminium 90 degree version. Aluminium saves weight, steel costs less and takes abuse better. If the car is a road or club car, steel is usually the sensible answer. If you are counting grams on a build, ask about the aluminium.
What universal means here
It means these are not cut for one car. They still have to match the bolt spacing of your seat, and seat makers do not all use the same one. Sparco and OMP share a common spacing, Cobra and Corbeau use their own, and Recaro is different again. Send us the seat model before you order and we will confirm it.
What goes underneath
A vehicle specific Planted bracket, or your own subframe. Ask us if you are not sure which you need.
