If you’re researching TREQ profile sizes explained, you’re probably trying to answer one simple question: will this rig stay rigid, feel adjustable, and support future upgrades without turning into a messy project?
Aluminium profile rigs (often called “8020 rigs”) are popular because they let you move everything: wheel height, wheel distance, pedal angle, pedal height, seat position, monitor position, and accessory placement. But not every profile rig delivers the same real-world experience.
Profile size is not just about strength
People talk about profile size like it’s a “bigger is better” contest. In reality, profile size affects three things you will notice every day:
- Stiffness under wheel torque and pedal force
- Adjustment range (how far you can move hardware without weird brackets)
- Build cleanliness (space for routing and accessory mounting)
What each profile size feels like in practice
| Profile size | Typical role | What you feel | When it makes sense |
|---|---|---|---|
| 40×40 | Entry profile class | Lighter rigs, good starter builds | If you run lighter wheels/pedals and want low cost |
| 80×40 | Universal sweet spot | Handles most DD + load cell setups | Most people’s “buy once” tier |
| 120×40 | Extra headroom | More stiffness + more adjustment range | Great for clean builds, heavy peripherals and future upgrades |
| 160×40 | Flagship class | Maximum stiffness and modularity | Motion, high torque, heavy builds, long-term ‘endgame’ rigs |
Using TREQ rigs as examples
TREQ’s lineup makes the profile-size concept easy to understand:
- Entry-level rigs sit closer to the 40×40 / lighter 8020 idea (think “get started and upgrade later”).
- TREQ One represents the classic 80×40 “do it all” category.
- TREQ CXX is a 120×40 based approach if you want extra headroom and a clean look.
- TREQ Ace moves into 160×40 flagship territory for maximum stiffness and modularity.
The SIMGASM tier match
SIMGASM mirrors this logic in a straightforward way:
- SIMGASM Hobby simulator is the entry point when you want the price low but still want profile modularity.
- SIMGASM Club simulator is the universal 80×40 tier that fits almost all peripherals.
- SIMGASM Sport simulator adds size, adjustability, and cleaner routing with 120×40.
- SIMGASM Pro simulator is 160×40 flagship stiffness with thick plates for truly flex-free builds.
Decision rule that works for most people
- Controller or gear-driven wheel today: start entry level, plan the upgrade.
- Load cell + mid torque DD: 80×40 is the safe bet.
- High torque, heavy pedals, tactile, or motion: 120×40 or 160×40.

What actually creates flex in a profile rig
Flex is rarely “the profile size alone”. It’s usually the combination of:
- Lever length: long uprights amplify movement at the wheel.
- Connection style: small brackets vs larger plates, and how well they are tightened.
- Pedal leverage: high-force brakes reveal movement quickly.
This is why a well-designed 80×40 rig can outperform a poorly assembled 120×40 build.
FAQ
-
Is bigger profile always better?
Bigger profiles add stiffness and adjustment range, but they also add cost and footprint. Choose the smallest size that meets your upgrade plan. -
What matters more: profile size or wheel mount design?
Both matter. A strong wheel mount on a smaller rig can outperform a weak wheel mount on a bigger frame. -
Will 80×40 handle direct drive?
In many cases yes, especially at moderate torque, but high torque and heavy peripherals may benefit from 120×40 or 160×40. -
Why do people go 160×40?
For motion readiness, extreme rigidity, and maximum modularity over years of upgrades. -
What’s the biggest benefit of profile rigs?
You can change ergonomics and layout without replacing the whole cockpit.
