A pair of OMP ARS competition seats in fibreglass. Part number HA774E-X2.

The ARS is a roomier shell than most in the OMP competition range. OMP list it for all heights with a 36 to 38 inch waist bracket, which is a good deal more accommodating than the WRC-R or the First R, and it is the seat to look at if narrower shells have not worked for you.

Specification

Fibreglass, velour trim, FIA 8855-1999 homologated, fixed back, side mount, four and six point harness compatible, black.

Velour grips more than a smooth surface, which matters when you are strapped in hard and the shell is doing the holding. It also does not go cold and slippery the way vinyl can in an unheated garage.

Why a composite shell

It holds its shape under lateral load in a way a tubular steel frame with foam over it cannot quite match, and it weighs less. That is what separates the fibreglass seats from the steel framed TRS range below them, and it is what you are paying for. The approval is the same.

What else you need

Approved side mounts and a vehicle specific sub-frame per seat. An approved seat on unapproved mounts is not an approved installation, so the mounts are part of the job.

Seats only. Tell us the car and we will match mounts and frames, and ask us for the manufacture dates on current stock.

OMP seat size guide

OMP publish a full dimension table for every shell, which makes them the easiest brand to size from a measurement. Most models are one size, with XL versions on the HTE-R, WRC-R, HRC-R and TRS-E.

How OMP size their seats

OMP quote external width at the shoulders, external width at the base, overall height and, the useful one, the inner width at the belt holes. Compare that inner width with your seated hip measurement: you want 20 to 40 mm of room, no more. The XL shells add 20 to 45 mm of inner width and 30 to 60 mm of height.

The HTE-R is the mid-size shell at 390 mm inside; the HTE-R XL and WRC-R XL go to 415 mm; the TRS-E XS is the slim one at 330 mm. Carbon versions of the same model are a little narrower than the fibreglass ones, which is worth knowing if you are at the edge.

The WRC-R XL is the big oneAt 665 mm across the shoulders and 415 mm inside it is the widest OMP we list, and the only one we band to a 42 inch waist.

Every OMP shell in the table fixes through the side with four M8 8.8 bolts as a minimum. The TRS-E also takes bottom fixing.

Measure yourself first

Four numbers decide whether a seat fits. Take them in the clothes you drive in, and write them down before you compare models.

AWaistAround your natural waist, not your trouser size. Trouser sizes usually run an inch or two under the real figure, and the waist bands on our product pages use the real one.

BSeated hip widthSit on a hard chair with your feet flat and measure straight across the widest point of your hips with a rule or a straight edge, not a tape that follows the curve. This is the number that decides whether a fixed shell is tight.

CShouldersStraight across the back at the widest point. Fixed back seats hold you here, so a shell that is narrow at the shoulders is uncomfortable long before it is unsafe.

DHeight and torsoYour height, and if you are over 6 ft whether that is mostly leg or mostly body. A long body needs a taller shell with the head support set higher.

Before you order

Check the car, not only the driver. Transmission tunnels, door cards and B pillars are what stop a wide shell going in. Our seat mounting and fixing points guide covers what to measure.
Side mount and base mount shells are not interchangeable. Which one you need depends on the car and the subframe, so pick the brackets at the same time as the seat.
If you run a HANS or plan to, filter on HANS friendly. The shoulder openings are cut to clear the collar.
FIA seats carry an expiry date on the homologation label. Check what your championship accepts and how long the seat has left, particularly on discounted older stock.

Send us your measurementsWaist, seated hip width, height and the car. We have fitted a lot of OMP seats and will tell you honestly if the one you have picked is going to be tight. Call 0115 989 3488 or email Sales@GSMPerformance.co.uk.

Waist bands and heights are our product data, checked 6 September 2026. Dimensions and weights are from OMP’s race seat size guide.

Have you written anything about this exact product?
Yes, we have covered this exact product: Which Is Right For You? OMP Champ VS OMP ARS. That is first-hand coverage from our own builds and showroom, not brochure copy.

Will I fit in this seat?
The maker sizes this seat for drivers with a 36in to 38in waist. Those are the paper numbers; how a seat actually feels to sit in and climb out of is a different question, and our showroom team sit in these seats every day, so call us with your height and waist and we will give you the honest answer.

Is it FIA approved, and for how long?
Yes, it carries FIA 8855-1999 homologation. Every FIA seat has a not-valid-after year printed on its homologation label, and that label date is what a scrutineer checks, so look at the label on the seat you receive and check it against your championship regulations. Buying new means you get the freshest label the maker currently produces.

What do I need to fit it to my car?
This is a side-mount seat: it hangs between side brackets, the motorsport-style stack with fine height and angle control. You will need the car-specific frame, and a sliding runner if you want fore-and-aft adjustment. Our guide on base mount versus side mount walks through the whole stack, and tell us your car and we will quote the full kit.

Does it work with harnesses and a HANS device?
The shell takes 4 point compatible and 6 point compatible. If you are planning the full seat, harness, and HANS setup, tell us the car and we will spec it end to end.

How do I know it will feel right, not just fit on paper?
Fair question, because makers publish widths and weights, never feel, and two seats with identical numbers can feel nothing alike in the car. We keep the ranges on display in the Nottingham showroom, you are welcome to come and sit in them, and if you cannot get to us, call and describe your build, as the team sit in these seats every day. Our head support measurements guide shows the kind of real-world data we collect.
