Dear sim racers,

Today marks the day of launching a new era of Overpower products. We’ve come a long way in developing simulators using sheet materials, and from the beginning our enthusiasm has been to make Overpower products easy to use, affordable to acquire and innovative in design. Let us introduce you the OP Koivu – a Finnish-made sim rig that combines professional-level adjustability, a sturdy structure, and versatile expansion options. Perfect for both beginners and enthusiasts who want a frame that can withstand hardware upgrades for years to come – with best in class performance available only at 399 €.

Koivu grows with you – from your first laps to top -tier racing – handling everything from load cell pedals to the most powerful direct drive wheels with ease. And if you want to take the experience even further, you can easily mount bass shakers or add a HOTAS bracket for immersive flight simulation.

This is a rig that evolves with your passion – from entry level to pro.

Everything you need, all in one budget-friendly rig

Koivu comes fully equipped right out of the box, making it the most versatile sim rig in its price category.

Standard equipment included

• Wheel and pedal mount – adjustable and rigid, built to handle even high- end hardware
• Seat base – compatible with the most popular seats on the market (including Playseat models)
• Monitor stand – supports screens up to 34”
• Gaming platform mount – suitable for PC, PlayStation, or Xbox
• Handbrake and shifter mount – large mounting plate for all additional controllers

Optional accessory: OP HOTAS Mount

Wheel Mount – Rigidity and Adjustability Without Compromise

We believe a great driving experience comes down to three key factors – adjustability, rigidity, and compatibility.

The wheel must sit exactly where it feels natural to use, without causing fatigue even during long driving sessions. With Koivu’s high adjustability, you can fine-tune your driving position for lasting comfort and endurance.

Rigidity is equally important — every bit of flex or lateral movement translates into distortion in the force feedback you feel through your hands. Koivu’s five cross  supports eliminate unwanted movement, allowing you to sense driving telemetry with exceptional precision.

And with wide -ranging compatibility, setup is effortless — ensuring a smooth installation and perfect wheel positioning from the very start.

Features

• Five cross -supports – eliminate lateral movement and ensure rigidity, even under heavy force feedback
• Professional – grade adjustability – every driver can find their perfect position
• Wheel tilt adjustment: 53.5 °
• Height adjustment: 30 cm
• Full compatibility – pre-drilled mounting holes for the most popular wheel bases
  • Logitech, Thrustmaster , Heusinkveld, Asetek , Simagic , Simucube, Fanatec, and more

Pedal Mount – Stability and Adjustability for Every Driver

The most important feature of a pedal mount is its ability to handle heavy braking forces with ease. That’s why we added four cross-supports to the Koivu pedal platform — giving lightweight Finnish birch plywood the rigidity needed for precise and confident trail braking.

Adjustability and ergonomics are equally central to the design. The pedals must remain comfortable and natural to use, even during long driving sessions that demand both consistency and performance.

Features

• Rigid structure – designed to withstand the forces of load cell and hydraulic pedals
• Extensive adjustability – adjustable pedal plate angle and distance for optimal ergonomics
  • Tilt adjustment: 33.6 °
  • Distance adjustment: 28 cm
• Pre-drilled mounting points – compatible with the most popular pedal brands
  • Logitech, Thrustmaster , Heusinkveld, Asetek , Simagic , Simucube, Fanatec, and more
• Easy customization – additional reinforcements or personal
  modifications can be added to match your driving style

The screen exactly where it should be – stable and ergonomic

The primary purpose of the monitor stand is to ensure the optimal viewing angle and distance to the driver’s eyes — stable, ergonomic, and perfectly aligned. Three cross-supports keep the structure solid, while the lightweight yet durable birch plywood provides a firm foundation for your display, even during long driving sessions.

Developed with over a decade of sim racing experience, Koivu’s monitor stand is built around proven ergonomics. Its design is based on a tested and
recommended viewing distance of 45 – 65 cm, ensuring eye comfort and maximizing immersion.

Features

• Stable structure – three cross-supports eliminate wobble
• Wide adjustability – height adjustment 25 cm, distance adjustment 13 cm
• Smart positioning – multiple mounting options depending on driver preference and screen size
• Ergonomically tested – optimal 45 – 65 cm viewing distance based on years of experience
• Expandable – can be upgraded to a triple -monitor setup using OP Stand – alone Monitor Stands

Ergonomics without compromise – a seat base that adapts to every driver

The seat base’s primary role is to provide the driver with a natural, ergonomic driving position — stable, comfortable, and fully adjustable. The Koivu seat base is among the most adjustable on the market, featuring both tilt and height adjustments so every driver can find their ideal position, whether a beginner or a seasoned sim racer.

The structure is lightweight yet exceptionally rigid: four cross -supports and four longitudinal supports keep the base completely solid even under heavy use. It’s also designed for broad compatibility — most popular racing seats fit directly, and even Playseat seats can be installed easily with sliders.

The wooden construction makes customization effortless: you can, for example, mount bass shakers directly to the seat plate exactly where you want them using simple wood screws.

Features

• One of the most adjustable seat bases on the market – includes both tilt and height adjustment
• Rigid structure – four cross-braces and four longitudinal supports ensure stability
• Highly compatible – pre-drilled holes for most seat models, including Playseat with sliders
• Easy customization – bass shakers and other accessories can be mounted directly to the seat plate
• Adjustability: tilt adjustment 13 ° , height adjustment 5 cm

Strong, adjustable, and customizable handbrake & shifter mount – control stays in your hands

The primary role of the handbrake and shifter mount is to bring essential controls
within the driver’s immediate reach — as close to the wheel as possible for minimal hand movement and a natural driving feel. The mount is also designed to accommodate other important peripherals such as game controllers, keyboards, mice, and headsets.

The structure is solid and reliable: a four -way cross -supported frame keeps your controls stable even under heavy use. The large mounting plate allows for easy installation of all major handbrake and shifter models using standard wood screws and basic drilling, while the birch plywood material gives you freedom to add and position other devices as you wish.

A 6.5 cm height adjustment ensures optimal ergonomics, allowing every driver to find the perfect position — whether for rally, drifting, or circuit racing.

Features

• Robust construction – four-way cross -braced frame keeps controls stable under load
• Large mounting plate – plenty of room for multiple controllers and layouts
• Easy customization – mount your own devices with standard wood screws and basic drilling
• Height adjustment: 6.5 cm – designed for optimal driver ergonomics
• Natural positioning – handbrake and shifter placed close to the wheel for fast,
  intuitive use

The heart of your setup – clean, open, and ergonomic

The gaming platform mount integrates your PC, console, or other gaming platform directly into the simulator, turning Koivu into an ergonomic, all -in- one gaming hub. The placement is designed to support efficient cable management, reducing clutter and eliminating the need for extra -long cables.

The elevated, open design features ventilation and mounting slots that improve airflow and ensure optimal performance for your hardware. In addition, a dedicated
cable box neatly conceals excess cables, maintaining a clean look while protecting
them from damage.

The PC supports keep your hardware firmly in place. If desired, you can also secure your platform with additional straps, making it easy to roll and reposition the rig using the pedal stand’s wheels.

Features

• Integrates your platform – transforms the simulator into an ergonomic gaming center
• Smart placement – improves cable management and eliminates the need for long cables
• Open, ventilated design – airflow slots enhance cooling and performance
• Cable box – neatly hides and protects excess cables for a clean aesthetic
• Stable supports – hold the platform securely in place, with optional straps for added stability and easy movement
