This is the 6Sigma Sim Racing 6S-Slim cockpit, and for anyone looking to enter the world of aluminum profile rigs without breaking the bank, this is one that deserves attention. I have been testing it for a while now, putting it through daily use with a variety of gear, and today I am finally ready to share my full thoughts. This review goes over the good, the bad, what you should expect, and who this rig is best suited for.

One of the biggest improvements since my earlier reviews of 6Sigma’s products is the packaging quality. Every single component arrived fully wrapped in bubble wrap, plastic, and protective material. Nothing came scratched or scuffed, and every extrusion looked pristine straight out of the box.
There is one complaint here, but I will get to that later. Assembly was smooth and straightforward. Unlike before, the kit now includes physical manuals that are easy to follow. I built the entire chassis alone within a few hours, and considering how many aluminum rigs require a painful amount of trial and error, that is impressive. Everything fit tightly, and the hardware was properly labeled and organized.
While the bare chassis retails for around $300, the build you see here is equipped with optional accessories that noticeably improve the experience.
The most eye-catching add-on is the Galaxy Red seat, finished in a fluorescent suede-like fabric with soft front cushioning and a sparkly fiberglass shell on the back. It completely changes the visual personality of the rig.
However, the Heavy Duty Feet Stand is what transforms this setup. For an additional ninety dollars, the rig is elevated by about fifteen centimeters, which not only makes it easier to get in and out, but also gives it a far more premium stance. This one accessory improves the overall look more than anything else.
Because this is an aluminum profile chassis, it can also support keyboard trays, mouse trays, shifter plates, PC mounts, and other attachments. These are not necessary, but they help complete the setup and add convenience where needed.
The freestanding monitor stand ties everything together. Mine supports a 49-inch ultrawide, but it can accommodate up to a 55-inch TV. The key benefit is versatility. Since it is not rigidly attached to the cockpit, I can reposition it whenever needed. Throughout testing it has performed flawlessly and makes the entire build feel complete.
Despite the rig’s entry-level positioning, I wanted to push it as hard as possible. I mounted a 12nm direct drive base and stiff load cell pedals, both of which can overwhelm cheaper cockpits instantly.
To my surprise, the 6S-Slim handled it far better than I expected. There is some flex during extreme situations, but none of it affected my driving performance. I was comfortable running the Fanatec ClubSport DD at full force, slamming through gears on my H-pattern and sequential shifters, and heel-toe downshifting without concern.
It is not the strongest or stiffest cockpit I have used, but compared to similarly priced non-extrusion rigs or foldable entry-level frames, this is easily among the best performers for the money. Most users pairing it with mid-range gear such as the Moza R5 or Logitech Pro will experience almost no meaningful flex at all.
As expected with an aluminum profile chassis, adjustability is excellent. Steering angle, height, pedal distance, pedal angle, seat position, and accessory placement can all be tuned exactly to your preference.
There are several nice touches throughout the 6S-Slim that show 6Sigma has been refining their design. The optional shifter plate is large enough to fit both a shifter and a handbrake. The matte black finish looks clean and blends well with most setups.
Cable management clips and branded end caps are now included, along with floor-protecting studs and a seat slider on the optional bucket seat.
The seat is not included with the base 6S-Slim, which is a good thing for users trying to save money. You are free to use a seat you already own or pick up a used one locally, which many sim racers do.
For those considering the Galaxy Red seat specifically, I have no complaints. It is comfortable, supportive, and large enough for a wide range of body types. It also adds a unique visual identity to the cockpit.
There are only a few drawbacks worth mentioning.
If you eventually plan to install heavier motion systems, you will want a cockpit with larger beams, since a 40-series extrusion chassis is not ideal for heavy actuators. This is not a flaw, but simply part of the product category.
The plastic end caps are loose and tend to fall out easily, which is something many cockpits suffer from.
And lastly, although the packaging quality has improved dramatically, the amount of plastic waste with the 6S-Slim is extreme. I filled an entire large trash bag with bubble wrap and packaging materials, which is far from environmentally friendly. Everything arrived in perfect condition, but I wish there were a more balanced approach.
The 6Sigma Sim Racing 6S-Slim is easy for me to recommend. Despite being aimed at beginners, it offers strong performance, great adjustability, and a clean, modern look. Adding optional accessories enhances the experience even further, but even the base chassis is a solid and capable platform.
For anyone looking for an affordable way into the world of aluminum profile cockpits without sacrificing stability or upgrade options, the 6S-Slim should absolutely be on your shortlist.
