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.
Have you written anything useful for my car?
Yes: Budget Bucket Seats For A Honda Civic EK: What Fits, And What It Costs, and Honda Civic FK8 Type R with Sparco Evo XL & TRS Red Harnesses. Those are written around the same car, from real fittings and customer questions, so they are worth a look before you decide.
Will this fit my car?
This frame is made for the Honda Civic Fourth Gen (EC/ED/EE/EF/EX). Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on PCI frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Base mount or side mount, and does it matter?
This is a side-mount frame: the seat hangs between side brackets bolted through its flanks, the motorsport-style stack that gives fine height and angle control. Our guide on base mount versus side mount explains the whole fitting stack.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
