The Mirco RTS-2 Velour Diamond Stitch Red Edition FIA Motorsport Seat is a seat from Mirco Racing Seats, supplied from stock. Seat choice comes down to how the car is used. A fixed-back bucket holds you best and is what competition regulations expect, but it is harder to live with on the road. A reclining sports seat gives up some support for adjustment and everyday usability.

Choosing the right seat

Seat choice comes down to how the car is used. A fixed-back bucket holds you best and is what competition regulations expect, but it is harder to live with on the road. A reclining sports seat gives up some support for adjustment and everyday usability.

A competition seat needs a vehicle-specific fitting frame, and usually side mounts as well. Check the seat width against your car’s tunnel and sill before ordering, because a wide shell in a narrow car is a common and expensive mistake.

We have been supplying motorsport kit since 2003, so if you are unsure between two options, ask.

What to check before you order

A handful of details decide whether this seat suits your car. These are the ones that matter.

Approval: FIA 8855-1999. Check this against what you already run before ordering.
Brand: Mirco Racing Seats. Check this against what you already run before ordering.
Coloured Shell: Red. Check this against what you already run before ordering.
Construction: Fibreglass seats. Check this against what you already run before ordering.
Driver Height: Over 6ft, Under 6ft. Check this against what you already run before ordering.

If any of it does not match what you have, ask us before you buy.

Buying the Mirco RTS-2 Velour Diamond Stitch Red Edition FIA Motorsport Seat from SportSeats4u

Stock is shown live on this page. If you need the Mirco RTS-2 Velour Diamond Stitch Red Edition FIA Motorsport Seat for a specific event date, tell us when you order and we will confirm the lead time up front.

We have been in the motorsport trade since 2003, supplying club racers, race teams and workshops across the UK and exporting worldwide. That means the advice you get on fitment comes from people who use this kit, not from a spec sheet someone copied over.

If you are buying for yourself and you are torn between two options, call us. Five minutes on the phone usually settles it.

Mirco RTS-2 Velour Diamond Stitch Red Edition FIA Motorsport Seat questions

Will the Mirco RTS-2 Velour Diamond Stitch Red Edition FIA Motorsport Seat fit my car?

The seat needs a vehicle-specific fitting frame to mount to the floor. Tell us the car and we will confirm which frame you need alongside it.

Is it FIA approved?

Check the approval listed in the specification above. FIA-approved seats carry an expiry date, so check that too if the seat is for competition.

Can I use my standard seat belt?

With a reclining seat, usually yes. With a fixed-back bucket and harness slots, a harness is the safer answer, and some competition regulations require one.

How do I know what size I need?

Measure across your hips and compare against the seat width in the specification. If you are between sizes, go up, because a seat that is too narrow gets painful quickly.

Not sure the Mirco RTS-2 Velour Diamond Stitch Red Edition FIA Motorsport Seat is the right choice? Send us your car details or what you compete in and we will confirm before you order.

Bucket seat size guide

A bucket seat is sized on your hips, not your chest. That is the first thing to unlearn coming from clothing. Everything else follows from one measurement across the widest part of you when you are sat down.

Measure yourself sitting

Standing measurements are no use here. A bucket seat has fixed bolsters and it has to take you as you actually sit in the car.

1Sit on a hard, flat chairFeet flat, knees together, back straight against the chair back. No cushion.

2Measure across your hipsThe widest point, side to side, sitting down. This is the number that decides everything.

3Take your waist tooStanding, around the natural waist. Our seats are listed against this.

4Note your heightAnd whether you are long in the body or long in the leg, because it changes which shell suits.

Measure in what you will wearA race suit, and fireproof underwear under it, adds real bulk at the hips. If you drive in a suit, measure in it. Between two seats, that layer is often what decides it.

Waist size, and what each band means

Every seat on the site is listed against a waist band.

Waist band	What it is
28 to 32 inch	Small and narrow shells. Junior and lighter drivers
32 to 36 inch	The standard size. Most of the range sits here
36 to 38 inch	A half step up, mostly the wider Sparco and OMP shells
36 to 40 inch	The wide shells, and the ones to look at first if 32 to 36 is tight
40 to 42 inch	The widest we stock. Ring us, the choice is narrow

If you are between two bands, take the wider seat. A seat that grips at the hips is uncomfortable within twenty minutes and there is nothing you can do about it afterwards. A slightly wide seat can be padded out with an insert kit or a thicker cover.

Driver height

The second filter. It decides how far up your back the shell comes and where the head support sits relative to your shoulders.

Height band	What it means
Under 6 ft	Shorter shell, head support closer down
All heights	Deep enough to suit either
Over 6 ft	Taller shells with the head support set higher

If you are over six foot, filter on that first and then on waist. The tall shells are a much smaller part of the range and it is quicker to start from the shorter list.

Cobra seat dimensions

Cobra publish a dimension drawing for every seat they make, and these are their figures for the bucket seat families. Height is floor to the top of the shell with the base flat on the ground, width is across the widest point, depth is front to back. All in millimetres. The GT versions of the FIA seats are the same shell cut wider across the hips, so if a standard shell is tight, the GT is the next step.

Seat family	Height	Width	Depth	Weight (kg)
Nogaro (Street, Circuit, Club Sport)	910	560	710	7.9
Imola	900	590	730	10.3
Suzuka	900	590	730
Sebring	935	590	690
Evolution	935	555	720
Ultralite Carbon	915	590	610	6.9
Aqua 4×4	880	580	680

Every Cobra seat listing on the site carries these figures, plus the base width, on its Additional information tab, so you can check the exact model and edition you are looking at. Other brands publish theirs on the listing where available.

Seats sized in inches

The Kirkey aluminium seats and some of the Tillett composites skip the waist bands and give you an explicit seat width instead, measured across the inside of the shell at the hips. That is the most precise way any of these are sold, so if you have measured yourself sitting down you can match it directly.

Seat width	Who it suits
12 and 13 inch	Junior and very slim drivers
14 and 14.5 inch	Slim adult
15 and 15.5 inch	The common adult size
16 and 17 inch	Broader across the hips
18 and 18.5 inch	The widest, and the ones to ask about if others have been tight

As a rough rule, take your seated hip measurement and add an inch for a suit. That gives you the internal width you are looking for.

Construction, and how it changes the fit

Material	What it feels like
Fibreglass	The default. Stiff, well priced, a little heavier
Carbon fibre	Lightest and stiffest. The bolsters barely move under hand pressure
Steel frame	Reclining and road-biased seats, and the sim racing shells
Kevlar	Between fibreglass and carbon on both weight and price
Aluminium	Kirkey style, sized by explicit seat width rather than by waist band

It is not only about weight. A carbon shell is far stiffer, so the bolsters do not give at all and the seat feels a size smaller than a fibreglass shell on the same nominal band. Push on the bolsters of a cheaper fibreglass shell and you get some flex. On carbon you get none. If you are at the top of a waist band, that difference matters.

Three things to check before you order

Head support or not

About half the range has integrated head support and half does not. A seat without it is lighter and easier to see out of, and it suits a car that already has a headrest or a cage with a rear bar in the right place. A seat with it is the usual choice for circuit and rally work.

Harness holes

Almost every seat here takes a four point harness and most take a six point as well, but not all. The six point needs two extra holes low in the base for the sub straps. It is listed on every product under harness compatibility, and it is worth checking before you buy the harness.

HANS clearance

A good part of the range is listed as HANS friendly, meaning the shoulder openings are cut to clear a head restraint device without the collar fouling the shell. If you already run a HANS or you plan to, filter on it. A seat that is not HANS friendly will physically work but the device sits badly against the shoulder wings.

Side mount or base mountTwo ways a seat bolts in, and they are not interchangeable. Nearly all of our competition bucket seats are side mount, fixing through brackets on the sides of the shell; a few are base mount, bolting down through the seat base. Which one you need depends on the car and the subframe, not on the seat, so read our seat mounting and fixing points guide before you order the brackets.

Approval and dates

Most of the FIA seats we stock are 8855-1999, which is the long-standing competition standard. A smaller number are 8855-2021, the newer one, and a handful are 8862-2009, the tougher standard used in top-level racing. Road and Track seats are not competition approved and are meant for fast road and track day use.

FIA seats carry an expiry date printed on the homologation label. Check what your championship requires and how long the seat has left before you buy, particularly on a discounted older stock item.

Send us your seated hip measurementThat, your waist, your height and the car. Seats are the one thing worth getting right first time, and we 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, height and construction bands are from our product data, checked 2 August 2026. Cobra dimensions and weights are Cobra’s own published figures, read 3 August 2026.
