The Planted Steel Offset Universal Side Mount in black. Part number PSOSSM-B.
The offset version, which is what you want when the seat needs to sit further inboard or outboard than a straight 90 degree mount allows. That comes up more often than people expect: narrow footwells, transmission tunnels, cages, and door cards that a seat fouls on.
Offset or 90 degree
The 90 degree version is the default and it suits most installations. Reach for the offset when you have measured and the seat lands somewhere it should not. If you are ordering blind, tell us the car and the seat and we will say which is likelier to work rather than let you buy twice.
What universal means here
Not cut for one car, but still needing to match your seat’s bolt spacing. Sparco and OMP share a common spacing, Cobra and Corbeau have their own, Recaro is different again. Send us the seat model and we will confirm before you order.
What goes underneath
A vehicle specific Planted bracket, or your own subframe.
