If you’re comparing Sim-Lab’s P1X Pro and P1X Ultimate, you’re not asking “is it strong enough?” Both are built to handle serious direct drive wheels and heavy pedals. The real question is:
Which design makes your setup easier to build, adjust, and expand over the next few years?
This guide breaks down the differences that matter in day-to-day use: upright geometry, slot access, accessory mounting, and how to plan your monitor strategy.
The two design ideas in one sentence
- P1X Pro: a high-end profile cockpit built for rigidity and adjustability.
- P1X Ultimate: an evolution that emphasises straight uprights and slotted/accessible profiles to make adding accessories more intuitive.
Why upright geometry matters more than you think
Most buyers focus on profile size. But the biggest “feel” change often comes from upright geometry:
- Straight uprights keep the wheel’s horizontal distance more consistent when you raise or lower wheel height.
- Angled uprights can make the wheel move closer as you raise it (because you’re moving along an angle). For some drivers that’s perfect; for others it creates a fit problem.
Before you decide, measure your current comfortable position:
- Seat reference: sit with your shoulders against the seat and measure from shoulder to wheel rim.
- Wheel height: measure from the floor to the center of the wheel.
- Elbow angle: aim for a relaxed bend (not locked out).
If your ideal wheel is high and far away (tall GT seating, truck, rally), straight uprights often make adjustment simpler.
Slotted profiles: not a marketing gimmick
“More slots” sounds like marketing until you start mounting real-world peripherals:
- button boxes and dashboards
- keyboard trays
- shifters and handbrakes
- stream decks, tablet mounts and microphone arms
Slot access determines whether you can mount something exactly where you want it or whether you need extra brackets (and extra flex points).
If you already own a P1X Pro and you’re fighting accessory placement, the fix is often simpler than swapping rigs: add a rigid side arm and mount the accessory closer to the structure. On SIMGASM builds this is what the Apex side mounting arm and Core side mounting arm are for.
Wheel mounts: choose based on torque and ergonomics
For high-end rigs, wheel mount choice is less about compatibility and more about the balance between stiffness and adjustment speed.
A practical rule:
- Pick the mount style that lets you set your wheel height, reach, and tilt without compromising stiffness.
- Then lock it down and stop adjusting it every week—consistency is speed.

Monitor mounting: integrated looks clean, freestanding stays calm
High-end rigs make it tempting to bolt the monitor to the cockpit and call it done. Sometimes that’s perfect. Sometimes it’s a long-term annoyance.
- Integrated is clean and compact. On SIMGASM, the Apex integrated triple monitor stand is designed for integrated triple builds.
- Freestanding isolates vibration and makes fine alignment easier over time. See the Apex freestanding triple monitor stand.
If you plan motion later, freestanding often avoids rework.

How SIMGASM fits into the same decision
If you like the “P1X Ultimate idea” (more usability for mounting, easier clean builds), that’s the same reason SIMGASM is split into tiers:
- SIMGASM Club simulator is the universal 80x40 platform.
- SIMGASM Sport simulator adds a larger footprint, stronger wheel mount concept and built-in cable routing paths for cleaner builds.
- SIMGASM Pro simulator is the flagship 160x40 tier for maximum adjustability and rigidity.
The main point: pick the rig that makes your future peripherals easy, not just the rig that looks best on day one.
FAQ
Is the P1X Ultimate “better” than the P1X Pro?
“Better” depends on your priorities. If straight uprights and easier accessory placement solve problems you care about, the Ultimate design direction makes sense. If you already have a stable setup and don’t change peripherals often, the Pro can be more than enough.
What’s the most common mistake when buying a high-end rig?
Buying for torque, but forgetting ergonomics and monitor planning. A premium rig is valuable because it lets you lock in a repeatable seating position and keep it consistent over long sessions.
