Direct drive wheel bases have become a popular upgrade for sim racers who want more responsive steering, clearer force feedback, and better control over the virtual car. However, choosing the right direct drive system is about more than chasing maximum torque. The right setup depends on your driving style, preferred racing disciplines, and the level of feedback you want from your wheel base.
The PXN VD Series includes three direct drive wheel bases: the VD4, VD6, and VD10, each offering a different torque level for different sim racing setups.
PXN VD10 direct drive wheel base, designed for sim racers who want stronger torque, precise steering response, and competitive-level performance.
PXN VD4 vs VD6 vs VD10: Choose the Right Direct Drive Wheel Base
| Model | Constant Torque | Peak Torque | Recommended For |
| PXN VD4 | 4Nm | 5Nm | Racers entering direct drive |
| PXN VD6 | 6Nm | 7Nm | Racers seeking balanced performance |
| PXN VD10 | 10Nm | 12Nm | Racers wanting higher torque output |
PXN VD4: An Accessible Direct Drive Option
The VD4 is designed for racers moving beyond entry-level wheels. It provides an accessible way to experience direct drive technology without requiring a high-end setup.
PXN VD6: The Balance Between Performance and Usability
The VD6 is a balanced sim race wheel base that combines strong feedback, precise steering control, and practical usability. It suits racers who want a meaningful direct drive upgrade for GT, Formula, and circuit racing setups.
PXN VD10: Built for High-Torque Setups
As a 10Nm direct drive wheelbase, the VD10 is designed for experienced racers who want stronger force feedback and a higher level of steering performance in their sim racing setup.
Direct Drive Servo Motor for More Responsive Feedback
Direct connection for faster force transfer
The PXN VD Series uses a direct drive servo motor connected directly to the steering shaft. Compared with traditional belt-driven systems that transfer force through additional transmission components, this design delivers a more direct connection between the motor and the wheel, allowing force feedback signals to be delivered more directly and with faster response.
Low-inertia design for quicker reactions
The 20-pole low-inertia motor is designed to respond quickly to changes in steering forces. When the car begins to lose traction or weight shifts during cornering, the wheel base can adjust its feedback output more smoothly, helping drivers react with greater control.
Clearer feedback during dynamic driving
In practice, this can improve the way racers interpret:
- front tire loading through corners
- grip changes during acceleration
- braking weight transfer
- corrections during oversteer situations
24-bit Magnetic Encoder for Precise Steering Control
High-resolution input for smoother steering response
While the motor determines how force feedback is delivered, the encoder determines how accurately steering movements are captured. The PXN VD Series uses a 24-bit magnetic encoder with over 16 million resolution points to detect wheel rotation with high precision.
Higher resolution allows the system to recognize subtle steering changes and translate them into smoother, more accurate input throughout the race.
Precision when every input matters
In competitive sim racing, small steering corrections can influence braking stability, corner exits, and overall lap consistency. The encoder helps drivers maintain better control when:
- adjusting steering angle while trail braking into a corner
- making quick corrections during traction loss
- maintaining stability through technical sections
- managing high-speed direction changes
Customize Your Driving Experience with PXN Software
Direct drive technology provides the foundation for detailed feedback, but different cars, racing disciplines, and driving conditions can require different steering characteristics. The PXN SimRacing PC Control Center allows users to adjust key settings such as force feedback strength, damping, and response characteristics.
These adjustments help racers refine the wheel base’s behavior based on their preferred driving style, from a heavier steering feel for cars that benefit from stronger resistance to a quicker response profile for vehicles requiring rapid steering inputs.
Intelligent Temperature Control for Long Racing Sessions
Direct-drive wheel bases generate continuous motor activity during operation, making heat management an important factor for long-term reliability. The PXN VD Series uses intelligent temperature control with thermal sensors to monitor internal conditions and help maintain stable operation during extended racing sessions.
An aluminum alloy chassis further supports heat dissipation, helping the wheel base remain dependable during longer practice sessions, endurance races, and repeated high-load use.
