Product Overview
The W4 is a 25 mm wider handmade version of the W3, which is a reclined seat with a formula race car driving position. This is the black GRP version with a backframe which makes it easily floor mountable with the M8 mounting bolts moulded into the seat. With the backframe the seat is self-supporting and easy to mount rigidly to the floor or on top of the Tillett TR1 seat adjustment runners. Seat belt harness holes are included. A five or six point harness is advised with any reclined seat. An alternative and popular covering option is a Dinamica® suede two-piece seat pad set which is a special-order item.
