If you’re researching TREQ CXX vs SIMGASM Sport, 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.

Why 120×40 rigs exist

Most people jump from entry rigs straight to 80×40. A 120×40 chassis is the next step for one reason: it gives you more headroom. Not only for torque and pedal force, but for how much you can adjust without compromising rigidity.

Spec snapshot

Clean builds are about more than zip ties

When you start adding peripherals (shifter, handbrake, button box, dash, bass shakers, maybe motion), cable management stops being a cosmetic issue. It becomes a reliability issue. A clean build is easier to:

• troubleshoot when USB devices disconnect
• upgrade without re-routing the whole cockpit
• keep quiet (no rattling cables hitting profiles)

How SIMGASM Sport approaches this

The SIMGASM Sport is built to stay clean without requiring a bag of clips. It uses internal routing via multiple passthrough points, so you can run cables from the back to the front and up the frame while keeping the outside of the rig tidy.

Which tier should you pick

• Go 120×40 now if you already own load cell/hydraulic pedals or a strong direct drive base, or if you want to add tactile/motion later.
• Go 80×40 if you’re on an entry wheelbase now and you mainly want a stable platform for your first serious pedals.

SIMGASM equivalents and upgrades

If you like the modularity of aluminium profile rigs, SIMGASM follows a clear tier approach. It helps you pick the right stiffness and adjustability without overbuying.

• Entry and budget friendly: SIMGASM Hobby simulator
• Most universal 80×40: SIMGASM Club simulator
• Clean routing and extra adjustability: SIMGASM Sport simulator
• Flagship stiffness for motion and high torque: SIMGASM Pro simulator

For comfort and long sessions, pair your rig with SIMGASM Core Recline seat or a bucket like SIMGASM Atlas GT seat or SIMGASM Atlas Formula seat.

Make your screen setup future-proof

If you plan to add tactile or motion, monitor stability becomes a big deal. A freestanding stand like SIMGASM Apex freestanding triple monitor stand keeps your displays independent from the forces in the cockpit. If you want maximum cleanliness and an integrated look, SIMGASM Core integrated triple monitor stand is a strong starting point.

FAQ

• How tight should profile bolts be?
  Tight enough that nothing shifts under force, but avoid over-tightening that strips threads. Tighten in stages and re-torque after a week.
• Do I need threadlocker?
  It’s not mandatory, but it can help on bolts that see repeated vibration. Use it selectively.
• Why does my rig squeak?
  Usually a slightly loose joint or a cable rubbing a profile. Find it by pushing on the rig while listening.
• How do I stop pedals from moving?
  Use proper mounting and make sure the pedal deck is clamped correctly. High-force pedals punish weak mounting.
• Do I need to re-check alignment?
  Yes, especially after moving the rig or changing hardware. Small shifts can change feel significantly.
