Complete fitting kit: side mounts included. This frame comes with its own side mounts, so any side mount bucket seat bolts straight to it. You only need the seat and the frame, with no separate side mounts to buy.
A PCI Racing adjustable seat mount for the Honda Civic, 1990 to 1991. Part number SM-90EF-A1.
The part number is the fitment here. EF is the chassis code for that generation of Civic, and it is a narrow year window: a car from 1992 onward is an EG and takes a different mount. Check the year before you order and send us the registration if you are not certain.
The low option
PCI’s adjustable mount gives the lowest possible seat fitment in their range. On a Civic of this age, where the standard seating position is high and the car is light enough that everything you add matters, that is usually the right choice.
The trade is the slider. The seat is set at installation and stays there, though the hardware interlocks into the slots in the seat base so the position can be changed later with one tool without removing the mount from the car.
Construction
Laser cut and CNC formed from one piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, five and six point sub belt mounting locations built in.
On a car this old
Check the metal round the factory seat mounting points before you spend. A mount works by feeding load into that structure and it can only do that if the structure is sound.
Side mount, handed, order twice for a pair.
