The Tillett W2i Carbon is a carbon and GRP racing seat, Road and Track approved. Part number W2i-Carbon-GRP. Construction is carbon fibre and GRP, black finish. Four-point harness compatible.
Mounts by base mount only. A back frame is available as an option for cars or regulations that require one. Seat cover options are Dinamica faux suede covered panels or bare shell.
Against the W1i Carbon: both are carbon and GRP construction, both are 4-point harness compatible, and both carry Road and Track approval. The practical difference is mounting. The W2i is base mount only; the W1i Carbon adds a side mount option. If your car has a fitting frame or floor setup that suits base mounting, the W2i works and costs a little less than the W1i. If side mounting is the right method for your car, the W1i is the seat to order.
Tillett do not publish a specific rolled-edges width figure for the W2i Carbon in the same way as the B-series seats. If you need to confirm the interior shell width before ordering, particularly for a car where the tunnel clearance is tight, ask us before buying.
We have stocked the full Tillett range since 2003. If you are fitting a W2i in a specific car and want advice on the bracket choice, give us the details and we will help.
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 base-mount seat: it bolts down through its base, the simpler stack for road cars. 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.
Tillett seats are custom-made to order
These carbon seats are handcrafted in the UK for each order. We do not stock or display them in the showroom, so everything is a special order placed with Tillett when you buy.
Lead times depend on the model and the options you choose, so ring us before ordering if you are working to a date.
Special order
Because each seat is made for you, our special order terms apply once production has begun.
Tell us your height, weight and the car, and we will confirm the right size and mounting before anything is made. Tillett sizing is specific and worth getting right first time.
