The Tillett T15VTI is a kart seat in the upper tier of the T15 range, sharing the same size options and material tiers as the T15VG but with a different shell profile. Part number TIL-T15VTI; the suffix varies by material and size, for example TIL-T15VTI-WF-L for white fibre in a large.
Available in four sizes: L, ML, XL and XXL. Three material options: white fibre at £204.75, silver fibre at £244.65 and carbon fibre at £321.30.
The T15VTI and T15VG are priced identically and use the same material options. The practical difference is shell shape. In kart seat design, shell profile determines how the seat holds the driver and how it manages lateral force through corners. The VTI and VG are two shapes at the same price point, and the right one depends on your kart type and driving position. If your class has an established preference for one profile, follow that. If you are choosing fresh, ask us or your kart supplier.
Both the T15VTI and T15VG sit above the T15STD and T15T in price. The higher cost reflects the shell design. Within this tier, material choice works the same way: white fibre is the entry option, silver fibre is mid-range, carbon gives the lowest weight.
No HANS compatibility. No harness compatibility (standard kart belt only). No headrest.
We have stocked the Tillett range since 2003. Tell us the kart and we will help you choose.
Will I fit in this seat?
Send us your height and waist size and we will confirm the fit. how a seat actually feels to sit in is a different question, and our showroom team sit in these seats every day, so call us and we will give you the honest answer.
What do I need to fit it to my car?
The car-specific frame for your vehicle, plus 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.
How do I know it will feel right, not just fit on paper?
Makers publish widths and weights, never feel, and two seats with identical numbers can feel nothing alike. We keep the ranges on display in the showroom, you are welcome to come and sit in them, and our head support measurements guide shows the kind of real-world data we collect.
