The SIMSONN Plus X is a dedicated three-pedal set engineered for desktop motorsport enthusiasts who want authentic hydraulic resistance without investing in commercial-grade racing cockpits. Built with high-strength steel arms and a sealed fluid damper, the unit bridges the gap between basic mechanical springs and full-scale motorsport hardware by simulating the hydraulic backpressure of a real race vehicle. If you want a firm, progressive brake pedal that rewards deliberate muscle memory during trail braking, this configuration delivers excellent mechanical fidelity right out of the box.
This pedal set is tailored specifically for PC drivers using Windows who mount their gear to dedicated cockpits or rigid wheel stands. The progressive resistance profile provides immediate consistency benefits in competitive sim racing titles where precise brake modulation determines corner exit speed. However, drivers seeking multi-platform compatibility for gaming consoles or those looking for a lightweight desk setup with an integrated heel plate should look elsewhere, as this set requires a secure mount and operates strictly on PC hardware.

Hydraulic Braking System and Pedal Resistance
The defining element of the SIMSONN Plus X pedals is the advanced hydraulic brake assembly, engineered to replicate the non-linear hydraulic pressure curve found in real motorsport braking circuits. Conventional sim racing pedals often depend entirely on linear coil springs or basic polyurethane stoppers that compress evenly throughout pedal travel. In contrast, the SIMSONN Plus X hydraulic brake incorporates a dedicated fluid cylinder that dampens the travel speed of the pedal arm both on entry and release. This fluid resistance prevents abrupt mechanical spikes and ensures that initial pedal compression requires smooth, deliberate foot input.
As you depress the brake pedal further into its stroke, the hydraulic displacement combines with the internal resistance stack to create a progressive wall of backpressure. This progressive ramp mirrors how physical brake pads compress against spinning steel rotors as fluid pressure multiplies throughout an automotive brake line. Rather than relying purely on positional travel distance, your leg learns to gauge braking power through applied physical pressure, allowing for significantly cleaner trail braking into tight apexes without prematurely locking up tires.
Rebound control is equally vital during high-speed deceleration. Because hydraulic fluid resists instantaneous displacement, the pedal arm does not violently snap back the moment your foot eases off the faceplate. This steady damping allows drivers running complex physics engines on a high-performance PC equipped with an intel core ultra 7 system to modulate brake release smoothly, preserving front-end grip and avoiding unwanted chassis pitching during corner entry.
Damping Customization and Elastomer Options
Driver preferences vary widely across racing categories, ranging from the long, compliant travel preferred in rally stages to the ultra-short, rock-hard pedal throw required in modern open-wheel formula cars. To support these varied driving styles, the SIMSONN Plus X damping assembly includes three distinct elastomer hardness ratings: 60HA, 70HA, and 80HA. The Shore hardness rating scale indicates material stiffness, meaning the 60HA elastomer compresses with moderate resistance, while the 80HA option yields a stiff, unyielding threshold designed for high-force braking.
Fine-tuning does not end with elastomer hardness alone. The package supplies thirteen modular spacers that let racers adjust the pre-load and progressive ramp of the pedal stroke. By alternating soft and firm elastomers separated by spacers, you can create a distinct two-stage brake feel where initial travel takes up virtual pad clearance before encountering a dense hydraulic wall. Alternatively, stacking high-durometer elastomers with minimal spacing creates a short-throw pedal suited for drivers who rely strictly on heavy foot pressure.
Changing these mechanical components is straightforward and does not require opening the sealed hydraulic cylinder or handling loose fluid. Drivers simply release the retaining assembly on the rear shaft, swap the desired elastomer durometers and spacers, and lock the unit back into position. This level of physical customization ensures that pedal resistance matches your exact driving posture and virtual car class without messy maintenance routines.
Build Quality and Mechanical Construction
Rigidity under load is essential for hydraulic simulation hardware, and the SIMSONN Plus X specs emphasize structural durability throughout. The entire assembly is constructed from high-strength steel cut into reinforced side plates, base brackets, and pedal arms. With a total weight of 7 kg across the three individual modules, the unit resists lateral twisting and flex even when subjected to emergency braking forces during close wheel-to-wheel competition.
Smooth, consistent pivot articulation is maintained via a specialized dual-bearing design integrated into every pedal joint. Each arm rotates on a pairing of flange bearings and plane bearings, which work together to distribute torsional stress evenly across the rotation axis. This configuration eliminates the unwanted horizontal play, squeaking, and metal-on-metal friction that often develop in entry-level pedals using simple through-pins or plastic sleeve bushings.
The physical layout of the SIMSONN Plus X P3 H3 package includes three independent standalone pedal assemblies: throttle, brake, and clutch. Each unit measures approximately 9.84 inches in height, 6.81 inches in depth, and 3.15 inches in width. The manufacturer ships these pedals without a baseplate, meaning they are designed to bolt directly onto an aluminum profile cockpit, custom pedal deck, or dedicated wheel stand. Attempting to use these individual pedals unbolted on carpet or bare floors is impossible due to the high operating forces required to actuate the hydraulic brake.
Software Calibration and Electronics
A reliable physical mechanism must be supported by responsive electronic signal translation, and the SIMSONN Plus X for PC addresses this through an upgraded external control box. The enclosure is reinforced to provide robust anti-interference shielding against electromagnetic signal noise emitted by direct-drive wheelbases and nearby power supplies. The control box connects directly to the PC using a corded electric USB-C cable, ensuring stable, jitter-free signal communication across Windows 11 and earlier Windows desktop environments.
Digital calibration and curve manipulation are handled through the SIMSONN Manager software. This utility provides full control over pedal behavior, enabling drivers to set custom dead zones at the top and bottom of the stroke to prevent accidental dragging. Users can also configure non-linear pedal response curves, allowing for fine initial modulation in low-grip conditions while retaining full stopping power at maximum exertion. All customized settings can be saved to individual profile files and reloaded with a few clicks when switching car classes.
In addition to standard pedal calibration, the upgraded control box incorporates three dedicated vibration module ports. These ports support direct integration with SIMSONN VAM, VAM RPO, and VAM Neo vibration motors to provide tactile telemetry feedback straight to the pedal arms. When configured alongside simulation software running on graphics-heavy systems powered by an msi nvidia geforce rtx 5070 ti, these haptic motors deliver tactile pulses for ABS engagement and wheel traction loss, providing an extra sensory layer to help you stay on the limit.
Throttle and Clutch Ergonomics
While the hydraulic brake serves as the centerpiece of the set, the accompanying throttle and clutch pedals on this SIMSONN Plus X sim racing set provide complementary mechanical adjustability. The throttle pedal utilizes a linear return spring calibrated to offer smooth resistance throughout its travel arc. This balanced resistance prevents accidental over-application of the throttle when balancing a high-horsepower car on corner exit, and the mechanical throw can be adjusted to match your ankle ergonomics.
The clutch pedal features a digressive pivot linkage engineered to simulate the distinct release point of an automotive clutch pressure plate. During the initial portion of travel, pedal resistance increases steadily until it reaches a mechanical tipping threshold, after which resistance drops off sharply. This mechanical progression provides clear tactile confirmation when the virtual clutch plates disengage, enabling authentic standing starts and smooth manual heel-and-toe downshifts.
Both the throttle and clutch share the high-strength steel side plates, durable finish, and dual-bearing assemblies found on the brake unit. The pedal faces feature textured grip patterns to keep your feet planted during aggressive footwork. Because the metal edges are firm and defined, using thin-soled sim racing shoes or athletic sneakers is recommended for optimal comfort during extended endurance racing stints.
