What it is
The Sim-Lab P1-X Pro is the redesigned version of the rig that has been the default aluminium-profile recommendation in sim racing for years. Sim-Lab kept the strength and adjustability of the original P1-X and reworked it to cut weight, cut cost and make it simpler to build. It is built from 40-series profile, ships as a box of beams and hardware from Sim-Lab’s Netherlands facility, and includes the profiles, mounting hardware, a wheel deck or front mount, a pedal deck, a side accessory mount, seat bolts and an adjustable feet set. At around $873 / £690 for the frame on its own it sits at the top of the consumer profile tier, not the mid-range.
Who it’s for
You are the right buyer if you are running, or about to run, a strong direct-drive base and you want a frame that will not flinch under it. The 40-series profile and Sim-Lab’s thick cast-aluminium brackets are the point of the thing, and they hold the wheel planted exactly where lighter entry rigs start to twist. It also suits anyone who wants a profile rig they can keep and upgrade for years, since every mounting point uses standard T-slot hardware, so third-party accessories fit without adapters.
You are the wrong buyer if you are on a tight budget or you mostly run a belt or gear base. At this price, and with several parts sold as paid extras, the P1-X Pro is more frame than a low-torque setup needs, and a cheaper folding or steel-tube cockpit will do the job for less.
In use
The headline is rigidity. Put 90 to 100kg of force through the brake and the base does not bow, the seat back does not move, and there is no damping of the force feedback through the uprights. It is every bit as rigid as the original P1-X that has been a daily-driver benchmark for years. There is a tiny dip in the optional pedal tray under a hard stab on the brake, visible on camera but not something you feel through the pedal, and a little vibration carries through a stiff shifter, but the frame itself stays solid.
The build is one of its quiet strengths. Sim-Lab redesigned the joints so almost none of the usual corner brackets are needed: most 90-degree connections are a single bolt straight into a tapped thread, which keeps the rig clean and the assembly fast. The spring-loaded roller-ball T-nuts slide and lock in place rather than dropping to the bottom of the channel, which makes mounting accessories far less fiddly than the spring-leaf nuts on rival rigs.
Adjustability is the other strength. The feet, pedal tray, wheel deck, seat position, accessory arm and integrated monitor mount all adjust independently, and the monitor mount uses a clever drop-in bracket with grub screws so you can dial in the last percent of monitor angle with a spirit level rather than rebuilding the joint.
What to watch out for
The price is the first thing to sit with. At around $873 / £690 for the frame, the P1-X Pro is a top-tier purchase, and the total climbs once you add the optional pedal tray, seat rails, handbrake mount and the seat itself, which is not included. Cost the full build before you commit.
A few specific niggles are worth knowing, none of them dealbreakers. Sim-Lab hollowed out the middle of the main profile to save weight and cost, so the inner channels are missing, which makes mounting some motion brackets and off-centre accessories more awkward. The wheel-deck uprights sit on a 20-degree slant, so anything you bolt to them moves closer or further away as you raise or lower it, which is fiddly if you reposition often. It is also worth checking your profile on arrival: there has been a report of two pieces turning up with paint defects from poor dusting before powder coating, which Sim-Lab replaced and said is not the normal experience.
It is also a proper cockpit at 1350mm long and 680mm at its widest, not a folding stand, so it wants a dedicated space. Plan the footprint before it arrives.
Where it sits in 2026
Against the Trak Racer TR160S and the Advanced SimRacing ASR-6, the P1-X Pro trades nothing on rigidity and wins on the build experience thanks to the bracket-less joints and the roller-ball T-nuts. It is the safer pick over a steel option like the Playseat Trophy if you want full T-slot expandability. The reasons not to buy it are the price and the footprint rather than anything it does badly. If you want one profile frame that will carry a strong DD base for years and you value a clean, fast build, it earns its long-standing reputation. If value per pound is the priority, shop the wider profile tier before committing.
