Sim racing · head‑to‑head
Choosing between these two sets comes down to a choice between plug-and-play simplicity and high-performance pressure braking. The RACELINE PEDALS III offer a reliable metal build for mainstream racers, while the Simsonn Plus X Racing Simulation Pedal targets budget-conscious enthusiasts demanding a load cell.
The Simsonn Plus X suffers from hit-or-miss quality control, including dead load cells, faulty control boxes, and defective hydraulic dampers out of the box. Furthermore, you will likely need to ground the pedals to your rig to prevent electromagnetic interference (EMI) from causing input flickering, and the plastic throttle spring holder is a known failure point.
The RACELINE PEDALS III can be upgraded within its own ecosystem using Thrustmaster's official Load Cell kit. However, purchasing this official upgrade pushes your total investment over $300, making it less competitive against factory load-cell alternatives.
If you want a hassle-free, reliable metal build that plugs directly into your existing setup, the RACELINE PEDALS III at $149.96 is a safe stepping stone despite its loose RJ12 cable quirks. However, serious racers looking to master trail-braking will find the Simsonn Plus X at $191.59 far superior due to its 200 kg load cell, provided they are willing to tackle potential EMI grounding issues.
