Wheelbase Side Mount Pro

The Wheelbase Side Mount Pro is a heavy-duty sim racing wheelbase side mount system engineered for modern direct drive wheelbases. Built around rigidity, adjustability, and long-term durability, the Side Mount Pro ecosystem delivers clean fitment and mounting support for multiple wheelbase platforms.

Available in multiple mount configurations, the Side Mount Pro can be configured for modular front plate compatibility or dedicated direct side mounting for select wheelbase ecosystems including Fanatec, SIMAGIC, and MOZA.

By combining CNC-milled aluminum chassis brackets with laser-cut steel wheelbase brackets, the Side Mount Pro delivers the rigidity needed for high-torque direct drive systems while maintaining the flexibility to support different mounting styles and wheelbase layouts.

Integrated Front-to-Back Adjustment

All Side Mount Pro configurations include 45mm of front-to-back adjustment, allowing you to move the wheelbase closer or farther away without repositioning your seat or uprights.

Slotted mounting points make setup straightforward while locking down securely once tightened, helping maintain alignment and rigidity under heavy steering loads.

Purpose-Built Materials Where It Matters

• 10mm CNC-milled aluminum chassis brackets provide precise fitment and long-term durability where the mount connects to the rig.
• 5mm laser-cut steel wheelbase brackets add stiffness and resistance to flex where wheelbase loads are highest.
• All major components are finished in black powder coat for a clean, professional appearance.

This hybrid construction places strength where it matters most without adding unnecessary bulk or weight.
