The W4 is a very inclined seat used primarily in vehicles that use a Formula car seating position. This seat is a wider version of the W3 seat. In addition to the single skin shell, the W4 can be bought with an optional back frame. This secondary moulding bonded to the back allows the seat to be bolted rigidly to a floor or runner system.
(It is not recommended to use a runner adjustment system in a race vehicle) Bought as a single skin shell the seat requires customer made brackets to fit the chosen vehicle.

Key Features:
- The W4 is 25mm wider than the almost identical W3, making it a great option for those drivers over 100kg and with a waist size larger than 36 inches.
- Body mirroring shape gives the driver full support, helping reduce fatigue and ensure comfortability even over long periods of time.
- No headrest.
- The W4 weighs approximately 2kg without the backframe and 3.6kg with the backframe.
- Low profile moulded seat belt harness holes are included, enabling 5 or 6 point race harness to be used.
- Custom brackets will need to be made by the customer to fit the single skin model
