Description
The Tillett C1 Carbon is a premium FIA 8855-1999 homologated auto racing seat. The genuine carbon fiber shell is contoured to leave the shoulders free for unhindered steering. The C1 incorporates side helmet supports, making it the first "full-containment" seat from Tillet.
Like all Tillett auto racing seats, the C1 draws on extensive experience in karting, where the seat is a working part of the suspension and must be a perfect fit to the driver. While other brands start with a rectangular shell and fill it with padding to fit the driver, the shell of the C1 is contoured to fit the driver without any excess padding. This allows more contact for better control, while also allowing the driver to sit lower than most other brands.
Based on the popular C6 Screamer seat, the C1 is already very narrow at just 44cm (47cm for XL) at the widest part of the rolled lip edge, but for the most cramped cockpits Tillett also offers an "Edges Off" option which shaves 3cm from the width. Note that this option makes the seat a little less forgiving when getting in and out. The rolled edge also contributes some fatigue resistance, so the "Edges On" version should be chosen if at all possible.
Five harness slots allow the use of 5- or 6-point racing harnesses. The 62° (from horizontal) seatback angle and 13° (from vertical) headrest angle are tailored for comfort when using a standard Model 20 HANS Device. Genuine carbon fiber shell has gloss black gelcoat on the outside and clearcoated carbon weave on the seating surface, with synthetic suede headrest pads. Weighs just 7.1 to 7.8kg (15.6 to 17.1 lb), depending on size and edge options. Designed and manufactured in the UK.

Note: The seat sides are angled (not vertical), so the use of matching Tillett mounting brackets (sold separately) is critical to avoid overstressing the shell:
