A frame built to handle direct drive

Sim-Lab has long been regarded as the gold standard for aluminum cockpits, and the P1X Pro raises the bar even higher. The guiding principle is simple: to provide a base so rigid that it doesn’t budge, even when faced with the most aggressive direct-drive setups. As soon as you assemble it and mount a steering wheel on it, the message is clear. Here, we’re not looking for a lightweight, portable compromise—we’re looking for absolute stability.

The backbone consists of massive 160x40 mm profiles at the base, 120x40 mm uprights, and a few 80x40 mm sections for the gearshift support. By comparison, many entry-level cockpits use only 80x40 mm sections throughout. Suffice it to say that the difference in weight and stiffness is immediately noticeable to the touch.

Sturdy aluminum and custom-made plates

What sets the P1X Pro apart from a simple assembly of bars is the design of the joints. Sim-Lab has replaced the universal brackets with dedicated sandwich plates, and many of the profiles come pre-drilled. As a result, most connections are made with a single M8 bolt, a washer, and sometimes a spacer, instead of using multiple brackets that need to be adjusted. The washers featuring the company’s logo and the black anodized finish give the kit a clean, professional look.

A clever design choice or an aesthetic decision, depending on your point of view: Sim-Lab has removed the internal grooves from the 160- and 120-mm profiles for a cleaner look. It’s visually appealing, but it also leaves larger gaps between the remaining slots, which can make it harder to install third-party accessories. Keep this in mind if you plan to mount equipment that isn’t from Sim-Lab.

What it's like once you're at the controls

That’s where the P1X Pro really proves its worth. We put the chassis through its paces with a sturdy base, and the results are clear: zero perceptible flex, even under hard riding. During hard braking, when we slam the pedals with 50 bar or more on a load cell, the structure doesn’t budge an inch. No unwanted vibrations, no twisting motion to interfere with the riding experience. The force feedback remains crisp and accurate—which is precisely the goal of a cockpit of this caliber.

Going into a turn, this rigidity is a game-changer. When you’re aiming for the apex and adjusting the steering wheel with pinpoint precision, you want the only movement to be the one you’re making—not that of a vibrating frame. The P1X Pro delivers on this promise. During long endurance sessions, the Speed 1 bucket seat with breathable mesh fabric does its job well: firm support, a comfortable seat, and a small pocket for your phone that doesn’t get in the way. Thinner drivers will be the most comfortable; those with larger waistlines might want to look for an alternative seat.

Adjust your position down to the millimeter

Modularity is the other major selling point. The pedal mount attaches directly to the base and slides a considerable distance—about a dozen centimeters forward and the same amount vertically—allowing you to switch from an upright GT position to a stretched-out, Formula-style riding position. The steering wheel mount, meanwhile, is adjustable for both height and angle, with several mounting options—at the front, on the side, or on the base—depending on your steering wheel brand.

The seat slides back and forth along a rail, and the adjustable feet allow you to compensate for a floor that isn't perfectly level. One caveat: all these adjustments require a wrench; there's nothing that can be done quickly or without tools. Once you’ve found your ideal position, it’s not a problem, but if multiple drivers share the cockpit, you’ll need to grab the Allen wrench every time there’s a driver change.

Assembly, like a premium flat-pack furniture set

Good news for those intimidated by aluminum: the P1X Pro is surprisingly easy to assemble. The illustrated instructions, in the style of IKEA, show the bolts to scale; the hardware bags are labeled; and the pre-drilled profiles eliminate the need to fiddle with brackets. It takes about three hours to set up the frame, a little longer for a beginner. You’ll need an 8 mm Allen wrench, a 24 mm flathead wrench, and a rubber mallet; no tools are included.

What kind of equipment can you attach to it?

When it comes to compatibility, the P1X Pro is designed for universal use. Like any good profile-style cockpit, it contains no electronics of its own: it can therefore accommodate any base, whether you’re playing on a PC, PlayStation, or Xbox, depending on your steering wheel. Front, baseplate, and side mounting options support Fanatec, MOZA, Thrustmaster, Simagic, Simucube, and others. The adjustable pedal mount accommodates virtually all load-cell pedals, and a pre-drilled mounting point for an in-cockpit display (DDU) is provided at the front. Several seats are supported, ranging from Sim-Lab’s Speed series to the Sparco Grid and Circuit II.

Things to Consider Before Giving In

Nothing is perfect. The finish, while very beautiful, shows marks quite easily, so be careful not to bump it during assembly. We also noticed a few minor quality control issues depending on the unit, such as a thread clogged by excess coating. The wide rubber feet must be removed to fit through a door. And you’ll need to be prepared to spend a significant amount: this product is clearly aimed at the high end of the market, with the chair and monitor stand quickly driving up the price.

Verdict

The P1X Pro is one of the most well-designed cockpits we’ve ever used. With exemplary rigidity, generous modularity, a well-thought-out design, and broad compatibility, it checks almost all the boxes for sim racers looking for a platform built to last. The price and the seat’s size are the only real drawbacks. If you’re using a high-torque direct-drive system and flex bothers you, this is a safe bet.
