Sim-Lab P1X Ultimate Review: Is It Worth It Over the Pro?
Short answer: The P1X Ultimate is the better P1X for builders who value straight uprights, fully slotted profiles and easier accessory placement. It does not replace the P1X Pro by being dramatically more rigid; it refines assembly and modularity, with a TFS frame price of €899.90 checked on 30 July 2026.

Why the Ultimate exists
Sim-Lab developed the Ultimate after feedback on the P1X Pro. The key change is not a new torque claim: it is the return of straight uprights and profiles with slots on all four faces. Dashboards, button boxes, keyboard arms and cable-management parts are therefore easier to align without working around angled members.
Assembly and long-term adjustment
Pre-drilled holes, sandwich plates and revised brackets reduce guesswork during the initial build. An aluminium-profile cockpit still requires time, floor space and careful squaring, but the Ultimate is designed to make later changes less awkward. This matters if the rig will evolve from a single screen to triples, add a shifter, or receive a motion system.
Choose the wheel mount before ordering
The Wheeldeck is the broadest consumer option. The Front Mount is intended for compatible front-mounted bases such as Simucube, Simagic and VRS models. The Fanatec DD mount is the focused choice for compatible Fanatec Direct Drive wheel bases. Always verify the exact model rather than relying only on the brand.
What is not included
The base cockpit is infrastructure: wheel base, steering wheel, pedals, seat and screens are not included. Seat brackets and sliders also depend on the selected seat. Budget the complete configuration, not only the frame.
P1X Ultimate vs P1X Pro
The Pro remains a strong option at €789.90. The €110 difference buys the Ultimate’s straight uprights, fully slotted quad-slot profiles and revised assembly details. Choose the Pro if its angled architecture already supports your planned accessories; choose the Ultimate when mounting freedom and cleaner future upgrades justify the premium.
Strengths
- Very rigid permanent foundation
- Excellent accessory placement through quad-slot profiles
- Three wheel-mount architectures
- Broad pedal and seat ecosystem
- Made in Europe with a three-year warranty
Trade-offs
- Seat and screens are additional purchases
- Large and heavy once fully equipped
- More assembly than a tubular cockpit
- Correct wheel mount must be chosen before checkout
- Only a €110 value gain if you do not need the revised profiles
Who should choose it?
It suits a permanent high-end build using a powerful Direct Drive wheel base, stiff Load Cell or hydraulic pedals, multiple accessories, triples or future motion. It is excessive for a lightweight entry-level setup or a cockpit that must be moved frequently.
Alternatives inside the Sim-Lab range
The P1X Pro is the closest lower-priced alternative. The GT1 Pro reduces the budget and visual mass, while the GT1 Evo prioritises value.
TFS verdict
The P1X Ultimate is not a mandatory upgrade from every P1X Pro. Its value is practical: cleaner geometry, easier accessory mounting and fewer compromises as the rig evolves. For a long-term flagship build, those refinements are more useful than a headline rigidity claim.

FAQ
Is the P1X Ultimate stronger than the P1X Pro?
Both target high-end rigid builds. Sim-Lab primarily presents the Ultimate as an ergonomic and modular refinement, not through a quantified rigidity comparison.
Is a seat included?
No. Seat, brackets and slider depend on the configuration selected.
Can an integrated triple monitor mount be added later?
Yes. Sim-Lab offers Integrated Vario single and triple options for the platform.
