Rock Solid Rigs

What seats fit the RSR-21? 👇

The short answer: almost any seat.

As long as the total width is 50cm or less, you can mount nearly any racing seat or seat runner to the RSR‑21.

The plywood seat mount is pre-drilled for Sparco seat and slider rail bolt patterns, and if you’re using a different seat, simply drill the required bolt positions into the mount.

No adaptors required. Ever!

Built for flexibility so you can run the seat setup that suits your sim racing style.

And if you’ve seen our exclusive RSR seat… that’s what we provide to our brand ambassadors as part of their setup. 👀

Nothing beats reading real feedback from real drivers! 🙌

We stand behind every rig we build and the service that comes with it, so hearing customers stand behind us too… that’s what its all about…

What do you think to your rig?⬇️

Your sim racing rig is the heart of the entire setup 🏁

Start with the right foundation and everything else can grow around it.
Wheels, pedals, monitors, shifters, accessories, they all rely on the cockpit. (So it’s got to be pretty sturdy, right?)

Most people upgrade their hardware multiple times. If your rig can’t handle those upgrades, it quickly becomes an expensive bottleneck.

Build the structure right once and your entire system grows with it.
