The HA737E is the OMP Classic single seat, the individual version of the pair listing. The seat uses a tubular steel frame with velour across the centre section and vinyl at the sides, taking its style from 1970s competition car interiors. A headrest is included, the bolsters are deep sided, and the OMP branding is kept subtle.
The tubular steel frame is strong without being heavy: the seat weighs 7kg complete, which is competitive with a fibreglass shell and unusual for a steel framed seat.
The approval, plainly
The Classic is not an FIA rated competition seat. The approval is Road and Track, which covers track days and road use. For Motorsport UK events where FIA rated seating is required, this seat does not qualify.
Against the Silverstone
It sits slightly above the Silverstone Classic, which is the low back vinyl alternative in the same range and the same 7kg. The difference is clear: the Classic Revival is a high back seat with a headrest and the velour and vinyl combination, reading as a proper period bucket. The Silverstone is low back, all vinyl, and designed for cars where headroom is tight or a headrest would foul a roll hoop.
If both could work, the choice is between wanting a headrest and a warmer interior feel, or keeping the seat profile as low as possible.
Tubular steel frame. Four point harness compatible. Base mount at 345mm x 271mm. Sold as seat only, no brackets included.
If you are replacing both front seats, the pair listing covers both in one order.
Have you written anything about this exact product?
Yes, we have covered this exact product: Discover Our OMP Classic Bucket Seat Line-Up, and Can I Fit OMP Classic Seats Into My Classic Mini?. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will I fit in this seat?
The maker lists no driver size restriction on this seat, so it suits the full range of heights and waists. 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.
What kind of car suits this seat?
Classic and retro vehicles, which is exactly what this shell is designed around. The low-back retro style belongs in a period build, not a modern car, however tempting the weight figure looks. If you are kitting out a modern road or track car, we will point you at the right modern shell instead.
Is this seat FIA approved?
No, this is a road and track day seat rather than a homologated competition seat. For events that require an FIA seat, look at the FIA-approved shells in the range, and ask us if you are unsure what your series needs.
What do I need to fit it to my car?
This is a base-mount seat: it bolts down through its base, the simpler stack for road cars. 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. 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.
