Sim racing · head‑to‑head
Choosing between these rigs comes down to whether you want a heavy-duty, ultra-thick profile foundation with some customer service risks, or a lighter, highly respected industry standard. The 6S-120 Chassis Special Bundle offers massive 40x120 profiles, while the GT1 Evo Sim Racing Cockpit relies on a lighter 40x80 frame.
The 6S-120 Chassis Special Bundle is frequently criticized for poor customer service, shipping delays, and inaccurate website stock status. Additionally, the GT1 Evo has 1x1 corner brackets that can crack if over-tightened or subjected to heavy body weight when climbing in.
If you run a high-torque wheelbase on the GT1 Evo, you may need to use Nord-Lock washers or upgrade to a dedicated DD bracket to prevent wheel deck slipping. You might also need to flip the seat brackets to get a comfortable GT driving position due to the high pedal plate.
If you want a bulletproof, ultra-heavy 40x120 frame and are willing to risk frustrating customer service and poor assembly instructions, the 6S-120 Chassis Special Bundle delivers massive physical stability. However, for most racers, the lighter GT1 Evo Sim Racing Cockpit is the smarter, more reliable buy, offering incredible rigidity and a much safer purchasing experience despite its minor hardware quirks.
