6S-120 V2 Sim Racing ChassisvsTR120S V2 Racing Simulator with Seat Slider Kit

The Bottom Line

Both the 6S-120 V2 Sim Racing Chassis and the TR120S V2 Racing Simulator deliver rock-solid, flex-free aluminum profile foundations capable of handling high-torque direct drive wheelbases. However, your buying experience will differ wildly based on which brand's notorious customer service and quality control quirks you are more willing to tolerate.

Watch out

Both brands suffer from frustrating logistics and quality control issues. You may face missing hardware, scuffed profiles, or split shipments where key accessories arrive weeks after the main frame.

Note

Because both rigs use standard aluminum extrusion, you can easily source your own replacement T-nuts and bolts from local hardware stores if your kit arrives incomplete.

Why choose 6S-120 V2 Sim Racing Chassis

7.2
Performance Rating
  • Uncompromising Rigidity: The 120mm anodized aluminum and reinforced steel frame remains completely flex-free under 25Nm+ direct drive torque and heavy load cell braking.
  • Intuitive Basic Build: While the instructions are poor, the physical assembly is straightforward for anyone who has previously worked with standard aluminum profiles.
  • Universal Compatibility: Easily mounts high-end direct drive wheelbases and universal bucket seats without requiring proprietary adapters.

Why choose TR120S V2 Racing Simulator

7.8
Performance Rating
  • TR One Ecosystem: The interchangeable TR One mounting system provides highly secure, specialized fits for major wheelbase brands.
  • Zero Flex Performance: The 120x40mm extrusion easily manages high-torque wheelbases over 20Nm and heavy braking forces.
  • Included Seat Slider: Comes packaged with a seat slider kit, saving you the hassle of sourcing a separate adjustment mechanism.

The Verdict

Both chassis deliver outstanding, flex-free driving physics once fully assembled. However, the Trak Racer TR120S V2 edges ahead slightly due to its superior mounting ecosystem, despite both brands struggling with quality control and shipping logistics.
