W4 Racing Car Seat
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 composite back frame. This secondary moulding bonded to the back allows the seat to be bolted rigidly to a floor or runner system. Please note that the backframe moulding is not Carbon Kevlar.
(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.
