If you’re shopping for your first “real” aluminium profile cockpit, two names come up constantly: the Sim-Lab GT1 Evo and rigs in the 80x40 class like the SIMGASM Club. Both target the same problem: give you a stable, modular platform that doesn’t wobble when you add a direct drive wheel and a load cell brake.
This guide focuses on what actually changes your driving feel: stiffness where it matters, adjustability, and a realistic upgrade path.
Quick verdict
- The Sim-Lab GT1 Evo is a classic entry point with a wheel deck and a pedal tray concept.
- The SIMGASM Club sits in the same “do-it-all” zone but is positioned as a step above budget rigs with an 80x40 structure aimed at broad hardware compatibility.
- If you already know you want motion, very high torque, or maximum cable management, skip the debate and look at SIMGASM Sport simulator or SIMGASM Pro simulator.
Key specs that matter
Specs evolve over time, so verify the exact version you’re buying. These are the decision-making categories:
| Category | Sim-Lab GT1 Evo | SIMGASM Club |
|---|---|---|
| Profile class | Primarily 80x40 with some 40x40 elements | 80x40 base structure (Club tier) |
| Wheel mounting style | Wheel deck; direct drive upgrade mounts are typically add-ons | Designed as a universal platform; Sport/Pro step up wheel-mount adjustability |
| Pedal mounting | Adjustable pedal tray concept | Profile-based adjustability; easy to add a rigid heel reference |
| Monitor strategy | Integrated options exist; freestanding often preferred for motion | Core integrated triple monitor stand / Apex integrated triple monitor stand or Apex freestanding triple monitor stand |
Why 80x40 aluminium profile is the “sweet spot”
When people say a rig “flexes”, profile size gets blamed first. In practice, flex usually comes from the wheel mount design, the pedal mount leverage, or simply a build that isn’t squared and torqued evenly.
That’s why 80x40 rigs are so popular: they’re stiff enough for most ecosystems, but still easy to adjust when you change wheels, pedals, seating position, or monitors.
Wheelbase mounting: wheel deck vs front mount
Your wheelbase mount affects both stiffness and ergonomics (wheel height and reach).
- Wheel deck mounting is straightforward and broadly compatible. It’s great for “get in and drive” builds.
- Front/side mounts typically tie the wheelbase into the uprights more directly and are common on higher-end rigs.
If you plan to move into higher torque later, or you like a high steering wheel position (tall-driver GT, rally, truck), consider a cockpit tier with a stronger, more adjustable wheel mount. That’s exactly where SIMGASM Sport simulator and SIMGASM Pro simulator sit.

Pedal mounting: where consistency actually comes from
Load cell braking is the quickest way to expose a weak pedal mount. If the pedal plate shifts under peak force, your brain can’t build a reliable “brake reference”.
What to prioritise:
- Angle range you can repeat without ankle strain.
- A stable heel point (a simple upgrade is a dedicated heel plate).
- Enough adjustment to match your seating style (GT vs formula).

Monitor strategy: integrated vs freestanding
If you run triples, the “stand decision” matters more than most people expect.
- Integrated stands are clean and compact (see Core integrated triple monitor stand or Apex integrated triple monitor stand).
- Freestanding stands isolate monitor vibration and make alignment easier over time (see Apex freestanding triple monitor stand).

Picking the right SIMGASM tier (if you want a future proof path)
SIMGASM is split into four steps so you don’t overbuy:
- SIMGASM Hobby simulator as the lowest-cost entry.
- SIMGASM Club simulator if you want an 80x40 cockpit that works with almost anything.
- SIMGASM Sport simulator if you want more size, more adjustability, and a cleaner cable-routing approach.
- SIMGASM Pro simulator if you want flagship rigidity and maximum adjustability.
If you’re unsure, the https://simgasm.com/pages/guide-tour helps you pick based on budget and hardware goals.
Recommended SIMGASM parts for GT1 Evo owners and new builders
- SIMGASM Club simulator as a universal aluminium profile base.
- seat bracket set + Atlas GT bucket seat if you want a supportive GT driving position.
- Apex integrated triple monitor stand or Apex freestanding triple monitor stand depending on your space and motion plans.
- Accessories for shifters, handbrakes and extra mounts (profile rigs are made for modular add-ons).
FAQ
Is an 80x40 rig enough for a high torque wheelbase?
Often yes, if the wheel mount and upright connection are designed well and everything is tightened correctly. If you’re planning motion or you want maximum adjustability, stepping up a tier can still make sense.
What’s the fastest way to make a new rig feel better?
Lock in your seating position, stabilise your heel point, and set monitor height + FOV. Those three changes improve consistency more than most hardware upgrades.
