The OMP HTC EVO VTR, homologated to FIA 8855-2021. Part number OMPHA0-0903-A01.
Current standard rather than the 8855-1999 most competition seats still carry, which means stricter impact testing and a longer legal life. On a seat at this price that second point matters: it stays usable for more seasons than an equivalent 1999 seat, so the cost per season is closer than the ticket prices suggest.
Airtex trim
The trim is Airtex, which is a breathable technical fabric rather than velour or vinyl. In a closed car on a hot day that is a genuine difference rather than a marketing one: a velour seat holds heat against your back and an open weave moves air through it. Over a long stint that shows up as being less tired.
Specification
Fibreglass shell, fixed back, side mount, four and six point harness compatible, black. OMP list it for all heights with a 36 to 38 inch waist bracket.
Mounting
The 8855-2021 approval applies when the seat is on the correct side mountings, which are sold separately. Approved shell on unapproved brackets is not an approved installation.
You also need a vehicle specific sub-frame. Tell us the car and we will make sure the mounts and the frame are right.
Ask us to read the manufacture date off current stock before you order.
Have you written anything about this exact product?
Yes, we have covered this exact product: OMP HTC EVO VTR Fibreglass Seat In-Store Showcase. 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 8855-2021 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.
