Supporting Our Customer At Donington With Tillett B6 Screamer Seats
Customer race car, December 2021
We spent a day at Donington with one of our customers and had a proper look around their Ginetta race car. The main reason for the visit was to see the Tillett seats we supplied in place, and to try them for comfort and support.
They look right at home in the car and they fit well. It was also a good chance to get a feel for what it takes to race something like this.
- Customer car: a Ginetta race car at Donington
- Seat: Tillett B6 Screamer in carbon, FIA 8855-1999
- Shell weight from 5.8kg
- Mounted on Tillett's 6mm aluminium side mounts

The Tillett B6 Screamer
The customer chose the Tillett B6 Screamer in carbon, and it suits the car well. The shell is light, which helps with the weight of the car, without giving up strength or support. It is moulded to hold the driver’s back and sides, which gives the lateral support and comfort that matter over a long race.
The B6 Screamer replaces the popular B6F. Tillett reworked the design to make it stronger while taking weight out, and the shell weighs from 5.8kg. The back is shaped with tight cockpits in mind, and the seat is approved to FIA 8855-1999.
Up close you can see the carbon weave of the shell and how the shoulder straps pass through the harness slots. The slots are sized to take top end harnesses, and the headrest pad carries the Tillett logo.
Tillett's seats come from years of making kart seats with little or no padding. That is where the direct, seat of the pants feel comes from.

The customer's set up
The seat sits on Tillett side mounts, made to line up with the bolt points on the sides of the shell. The TB F1 brackets, now listed as the PTBI, are 6mm aluminium and are made for the B6 Screamer and the B7. The bolt positions let the seat be tipped, raised and lowered to suit the driver.
Tillett’s brackets can also be used with its TR1 and TR3 adjustable runners. We advise against runners in a race car, though, because they are meant for road use.
The belts are Schroth. The harness we featured for a set up like this is the Schroth Profi 3x2, homologated to FIA 8853-2016. It has 3in shoulder straps, 2in lap straps with pull up adjusters, clip in fittings, and works with an FHR (HANS) device.
Schroth has been making four to six point restraints for all kinds of motorsport for more than 50 years, and its harnesses are used by race teams around the world.

Our Tillett and Schroth range
We carry Tillett’s race seats together with its own mounting brackets and fitting equipment, all made to work with the rest of the Tillett range. Getting the seat, the mounts and the harness right as a package is what makes a race seat work in the car.
Garreth’s advice for anyone putting together a race car is to start with what the class regulations ask for, then match the seat, mounts and harness to the driver. Our guide to fitting a motorsport harness covers the angles and anchor points.
