The W5 is a reclined version of the W1i shape with the driving angle suited to vehicles that are very low, such as the GT40. The lightweight handmade version only weighs 1.1 kg.
Seat belt harness holes are included. A five or six point harness is advised with a reclined seat. The W5 seat is a single composite skin and will need brackets made in order to fit the various vehicles.
