Classic Cobra Seats In A Datsun 240Z

Seat fitting guide

A question we get a lot is which parts you need to fit classic Cobra seats to a Datsun. We have been fitting seats to Datsuns and Nissans for many years, from the 240Z through to the 350Z, so we know these cars well.

The 240Z suits a period seat far better than a modern race bucket. This guide covers the Cobra GT3 Historic and the Cobra Classic GT, how they are mounted, and the Planted Technology bracket that puts them into the car.

Both are base mount seats, with no side mounts needed
Bracket: Planted Technology 240Z seat bracket, on the factory points

Choosing the seat

For a 240Z, the Cobra GT3 Historic is the seat most people ask about. It is a fixed back bucket on a steel frame, trimmed in black vinyl with an integrated headrest, and you choose anthracite or silver eyelets. Deep bucketed sides give well rounded support, and it is made for classic and historic cars where how the car looks is part of the job.

If you want a lower back, the Cobra Classic GT is cut low for traditional sports and classic cars, with more legroom than the standard Classic, and it weighs 6.7kg. Cobra hand trim both in the UK, so there is a wide choice of colours and materials. There are more classic seats in Cobra’s range, and the right size depends on your height, so tell us before ordering.

Both seats are road and track approved, not FIA homologated. That suits road use, shows and track days, but check what your class asks for if the car is going to race.

The GT3 Historic's harness slots take a 4 point belt only, with no 6 point routing. The Classic GT comes in two versions, plain or with side harness slots, and the slots cannot be added later, so choose the slotted one if you might ever run a harness.

Keeping the standard seat belts

If you want to keep the 240Z’s standard seat belts with your new Cobra seats, that is fine: these seats can be used with standard belts. It gives a factory fitted look with a far better seat, which suits a car like the Z.

If you plan to use the car on track more seriously, a 4 point harness through the seat’s slots is the next step, but the harness needs proper anchor points. Our harness fitting guide explains what is needed.

Fitting the seats to the 240Z

The Cobra GT3 Historic and the Classic GT are base mount only. They bolt straight down onto a frame through the base of the seat, without side mounts.

We recommend Planted Technology’s 240Z seat bracket. It picks up the factory mounting points in the floor, so nothing needs cutting, and the Cobra seats bolt to it through the base. The seat bolts to the bracket, and the bracket bolts to the floor.

Two things are worth doing first. S30 floors and the areas around the seat mounts are prone to rust, so look properly under the carpet before you buy anything. And keep the original seats and every fixing, labelled, because an interior that can be put back exactly matters on these cars. Garreth’s advice is to send us the chassis number, because Datsun changed the rear seat mounting partway through the S30 run, and we will confirm the right bracket.
