Have you ever noticed that once you’re strapped into your harness with a HANS device, the factory Lightweight Bucket Seat just doesn’t feel quite right anymore?

On the street, the seating position feels great. But once you install a roll cage, 6-point harnesses, and a HANS device, everything changes. You’re pulled deeper into the seat, your posture becomes more upright, your helmet gets pushed forward, and your natural sightline through the windshield just doesn’t feel as comfortable.

That was exactly the problem we kept running into on our own track and race cars.

After countless track days, race weekends, and coaching drivers, we decided to build a solution instead of simply living with it.

Introducing the SPM Seat Tilt Kit for the Porsche 992.1 GT3 OEM Lightweight Bucket Seats.

Why we developed it

The goal wasn’t simply to recline the seat.

We wanted to restore a natural driving position once you’re fully secured with a harness and HANS device.

By slightly increasing the seat tilt, the driver’s posture becomes much more natural. Your sightline through the windshield improves, your helmet no longer feels like it’s constantly being pushed forward, and long sessions behind the wheel become noticeably more comfortable.

It’s one of those modifications you don’t fully appreciate until you drive with it.

At SP Motorsports, we build products to solve problems we’ve personally experienced—not simply to add another part to the catalog.

If you’ve ever climbed out of your 992.1 after a long session with a sore neck or felt your seating position wasn’t quite right once the harnesses were tightened, this kit was designed for you.

I’m curious to hear from other 992.1 owners. Have you noticed the same issue after installing harnesses and a HANS device, or did you come up with a different solution?
