MOMO seat size guide

MOMO make the Daytona and Daytona Evo in three sizes and publish every dimension of each. The Start and Super Cup are one size.

How MOMO size their seats

Standard, XL and XXL are three shells, not three pad sets. The XL adds about 15 mm of inner width and 15 mm of height; the XXL adds 35 mm of inner width and 30 mm of height over the Standard. MOMO’s inner width at the belt holes (365, 380 and 400 mm) is the figure to hold against your seated hip measurement.

Our product pages band the Standard at 32 to 36 inch and the XL and XXL at 36 to 40. Both bigger sizes are the ones to look at if you are over 6 ft as well as broad, because the shell grows in height too.

Which MOMO fits you

Model Waist band Driver height Shell Approval
Daytona, Daytona Evo Standard 32 to 36 All heights Fibreglass FIA 8855-1999
Daytona XL, Daytona Evo XL 36 to 40 Over 6 ft Fibreglass FIA 8855-1999
Daytona XXL, Daytona Evo XXL 36 to 40 Over 6 ft Fibreglass FIA 8855-1999
Super Cup 32 to 36 Under 6 ft Fibreglass FIA 8855-1999
Start 32 to 36 Under 6 ft Fibreglass FIA 8855-1999
Daytona or Daytona EvoSame three sizes. The Evo has the HANS-friendly head surround and the Airnet cover; the Daytona is the plainer shell. Size them the same way.

All five are side mount with five harness slots. The Super Cup and Start have no side head protection, which suits an open car or a driver who finds the Daytona surround close.

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 MOMO 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 are MOMO’s own Daytona Evo table, read from momo.com the same day.

Have you written anything about this exact product?
Yes, we have covered this exact product: Momo Start VS Momo Super Cup: Driver Seat Profile, and Momo Start & Super Cup Seats Arrive In-Store. 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 under 6ft in height with a 32in to 36in 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 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.

Availability

Momo seats are not stocked in the UK

Not by Momo UK, and not by us. Every Momo seat is special order direct from Momo, so plan well ahead of the date you need it.

Allow 8 to 12 weeks. Dispatch times vary, so contact us for the precise position before you order.

If you have a deadline

Tell us the date when you enquire and we will speak to production and see what can be done. Doing that before you order is far more useful than after.
