Tillett B10 XL Racing Seat In Carbon Fibre For Road & Track

The Tillett B10 XL Racing Seat in Carbon Fibre is a premium lightweight seat engineered specifically for larger drivers who want exceptional support without sacrificing day-to-day usability. Designed and manufactured in the United Kingdom, the B10 XL builds on Tillett’s renowned B6 race seat shape, reworked to better suit road and mixed-use vehicles while retaining the strength and rigidity expected from a true competition seat. The XL variant offers increased width and capacity, making it ideal for drivers over 100 kg or with a broader frame, while maintaining a compact, low seating position that improves driving feel and vehicle control.

The B10 XL features swept-away sides that make entry and exit easier and allow convenient use of factory three-point seat belts, solving a common compromise found in more aggressive race seats. A slightly raised front edge supports longer legs and works particularly well in saloon cars with limited steering column adjustment, while the taller headrest ensures proper support for drivers with longer torsos. Constructed using a twin-skin carbon fibre laminate, the seat is exceptionally rigid yet weighs approximately 5.4 kg, making it a standout option for drivers who value both comfort and reduced vehicle weight.
