The HA756N is OMP’s Silverstone seat, named for the low back, open top silhouette that references early circuit cars. The construction is tubular steel with a full vinyl cover: smooth sides and a ribbed centre back and base cushion. Deep sided bolsters, subtle OMP branding, no headrest.
The tubular steel frame keeps it strong without the weight that usually comes with steel. The seat is 7kg complete.
The approval, plainly
Road and Track approval only, covering track days and road use. The Silverstone does not carry FIA 8855-1999 or 8862-2009 homologation. For any Motorsport UK event where FIA rated seating is specified by the regulations, this is not the correct seat.
Against the Classic Revival
The Silverstone sits just below the Classic Revival, and the two take a different approach at the same 7kg. The Classic Revival is a high back design with a headrest and a velour and vinyl mix, a proper period bucket. The Silverstone is low back, all vinyl and deliberately minimal.
For an open top car, or a build where the roofline is tight and a headrest would foul the roll hoop, the low back Silverstone is the practical option. For a car where the driver wants a headrest and a slightly more padded feel, the Classic Revival is the step up.
Four point harness compatible. Base mount at 345mm x 271mm. Sold as seat only, no brackets included.
Have you written anything about this exact product?
Yes, we have covered this exact product: Classic Mini With OMP Silverstone Seats Package!, and Our Silverstone Classic Bucket Seat. 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.
