Road race cars differ from oval cars in one practical way: the seating angle varies between a front-engined GT car, a mid-engined prototype, a rally car and a club saloon. The Kirkey 65 Series answers that with an adjustable back angle, set once during installation to match the chassis. The range covers everything from a near-upright touring car position to a more reclined sports car layout.

The shell is 5052-grade aluminium with a black cover included. Width options are 15, 16, 17 and 18.5 inches. Part number is 65-Series, and the listing covers the seat and cover.

The 65 Series does not have full containment sides or a separate head surround, which suits road race applications where the rulebook may not require containment and the driver values lighter weight and easier exit. If the class requires a containment head surround, the 71 Series (part 71-Series) covers road racing with full containment at a fixed 20 degree angle and accepts a six-point harness.

The 81 Series (part 81-Series) is the road race alternative sized specifically for the Spec Miata chassis. Side mounts (part 99214, listed separately) and a rear bracket (part 99212, listed separately) are not in the price. Tell us the car and class and we can advise on the mounting combination for this seat.

Kirkey seat size guide

Kirkey aluminium seats are sized by hip width in inches, not by waist. Measure once, properly, and the size picks itself.

How Kirkey size their seats

The size is the width across the hips inside the seat. Kirkey’s method: sit upright on a hard surface with your legs slightly apart and measure straight across the widest point of your hips with a rule or a straight edge. A tape that follows the curve reads wide. Measure in the clothes you race in; a suit only adds to the snug fit.

If your hips measure a size exactly, order that size. If you fall between sizes go to the nearer one, and if you are within a quarter inch of the larger size take the larger. A Kirkey should hold you at the hips without pinching; there is no foam to take up slack.

Which Kirkey fits you

Series	What it is	Widths (inch)	Layback
38 Series Standard	The all-round aluminium seat for saloon and oval cars	14, 15, 16, 17, 18.5, 20	10 to 20 degrees, multi-mount base
58LW Series Lightweight	Lighter version of the standard seat	14, 15, 16, 17	20 degrees
16 Series Economy Drag	Drag and straight-line seat	15.5, 17.5	Drag layback
24 Series Child Quarter Midget	Junior seat	10, 11, 13	8 degrees

Covers are separateKirkey seats ship as bare aluminium. The padded cover is ordered to the same width as the seat.

Kirkey seats are not FIA homologated. They are used in drag racing, oval racing and grass-roots saloon classes; check your championship regulations before you order.

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 Kirkey 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.

Widths are our product data, checked 6 September 2026. The measuring method and the layback angles are Kirkey’s own.

Will I fit in this seat?
Send us your height and waist size and we will confirm the fit. The paper dimensions only tell half the story, and our showroom team sit in these seats every day, so you get the honest answer rather than a guess from a chart.

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

Kirkey comes through European distribution

Every Kirkey seat we supply comes through European distribution rather than direct from the USA. Stocked models run on a 7 to 10 day delivery schedule from the day you order.

Special order models

Anything outside the stocked range is built and shipped to order. That takes between 2 and 8 weeks depending on the model.

Before you order

Tell us the model and the date you need it for. We will confirm whether it is a stocked seat or a special order, and what the lead time is at the moment, rather than leaving you to find out after checkout.

In-store displays:

We have a premium range of over 125 seats from brands including: Bimarco, Cobra, Corbeau, Sparco, OMP, Recaro, GP-Race, and Bride to name just a few brands we work with.

Alongside this, we also stock and display HANS devices, harnesses, race-wear, race-suits, FIA helmets and various other safety equipment. If you are looking to visit us to see and try any particular seat or product, please contact us in advance and we’ll be happy to help.

In-Store appointments:

Due to the specialist nature of our services, we do ask that you please contact us in advance to book an appointment. We have multiple slots available each day including selected availability at the weekend.

Working by appointment allows us to dedicate our time with you and provide a personal and professional service. We’ll always ensure you leave with the right equipment for your needs.
