Tillett B2 Carbon Epoxy Racing Car Seat by Tillett Seats. Here is what it is and what to check before you order. 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.

Brand: Tillett Seats. Check this against what you already run before ordering.
Brackets included: Seat only. Check this against what you already run before ordering.
Coloured Shell: Black. Check this against what you already run before ordering.
Construction: Carbon Fibre seats. Check this against what you already run before ordering.
Fixing Type: Side mount. 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 Tillett B2 Carbon Epoxy Racing Car Seat from SportSeats4u

Stock is shown live on this page. If you need the Tillett B2 Carbon Epoxy Racing Car 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.

Tillett B2 Carbon Epoxy Racing Car Seat questions

Will the Tillett B2 Carbon Epoxy Racing Car 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 Tillett B2 Carbon Epoxy Racing Car Seat is the right choice? Send us your car details or what you compete in and we will confirm before you order.

Tillett seat size guide

Tillett shells are thin single-skin composites with almost no padding, so the internal width is the seat width. Tillett publish it for every model, and the XL and W versions exist for a reason.

How Tillett size their seats

Tillett quote an external and an internal width for each shell. Because there is no foam to squash, your seated hip width has to fit inside the internal figure with 10 to 20 mm to spare. Every B-series shell has an XL, about 30 mm wider, and the W2i and W6 are the wide versions of the W1i and W5, made for drivers over 100 kg or over a 36 inch waist.

Several shells are offered with a rolled edge or a cut edge. The cut edge (B6-40, B7-40, B8-43) loses 30 to 40 mm of external width for narrow cars without changing the inside.

Brackets have to match the shellTillett brackets are angled to match the side of the seat: 8 degrees on the B2, 2 degrees on the B6, B7 and B8. A bracket at the wrong angle stresses the composite. Use a load-spreading spacer of at least 40 mm at every bolt.

Tillett dimensions

From Tillett’s dimension sheets, 2022 to 2025. Widths are the widest point.

W3, W4, W5	One size	All heights	GRP or carbon-GRP	Road and track
W6	Over 100 kg, over 36 inch	All heights	GRP	Road and track

The W-series shells are supplied single skin and need bespoke brackets, or the optional back frame on the W1i and W2i. The B6 comes bottom mount or side mount; the side mount version takes Tillett’s STB, VTB and Elise brackets.

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 Tillett 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 are our product data, checked 6 September 2026. Widths, heights and weights are from Tillett’s dimension sheets dated 2022 to 2025; blanks are where the sheet gives no figure.

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.

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 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. 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.
