The Z1 Interior is adorned in leather, end to end. From the seats to the centre console, the gaitor, door cards, and swerves around both seats to meet the dash in dark grey or green leather. The carpet came in three colours, green to match the green dash and yellow leather, dark grey carpet for the camo and light grey interiors and red carpet to match the red leather.
The Recaro bucket design seats were trimmed in 4 different styles.
Surprisingly none of the seat material came with any form of protection against the elements, including UV, which you would expect on a Roadster. Wear and tear is costly as the sections are no longer available, the material is not available and neither are the seats. If restoring, the seat itself can be dismantled into 4 basic components for restoring: The Seat base, Back rest, Side and Thigh support, the leather is bonded to the foam underneath, foam which deteriorates over time, sags and develops a sort of `wrinkly bum` effect, having lost some of its flexibility working against the leather.
To dismantle your seats, see the detailed guide Here.
The seats are secured by 6 studs, 2 up front and 4 behind, removable using a special tool.
Front Much of this is working in small cramped space, so mind your back. Push seat all the way back, using a torch and leaning into the car, peer under the seat at the seat runners. There are 2 studs, (one either side), using a long socket loosen both, but dont remove.
Rear Push seat forward and adjust for maximum lean, then remove 4 studs, (two each side). Keep these safe.
The seatbelt will be attached to the seat base, so place a very thick soft non abrasive blanket or duvet over the rear of the car.
Slide the seat runners backwards away from the front studs (that you loosened but did not remove), then firmly lift the seat onto the rear of the car, ensuring you clear any obstacles without making contact with anything and placing the seat onto its seat back (rear plastic).
