Feel the Road.
Not Just the Speed.

The Road Rumble Sim transforms your sim racing setup by bringing the track surface to life.

Powered by SimHub telemetry, this system delivers real-time haptic feedback directly to your rig—so you don’t just see the road… you feel it.

Every bump, curb, gear shift, and loss of grip is translated into physical feedback, adding a new layer of immersion that connects you to the car like never before.


How It Works

Using in-game telemetry, Road Rumble converts data into precise vibration feedback across your rig.

With multi-point motor placement, feedback becomes directional—so you feel where the car interacts with the track.

While SimHub offers a wide range of effects, we believe the most immersive experience comes from focusing on a few core sensations that truly matter—rumble strips and track surface detail. By prioritizing these key effects, you get a cleaner, more connected driving experience—one that enhances feel without overwhelming you with unnecessary noise.

That said, you still have full access to SimHub’s full range of effects if you want to go beyond our recommended setup.

Here’s what that feels like in practice:

  • Hit a curb → sharp, directional feedback on the left or right side
  • Ride aggressive rumble strips → consistent, textured vibration through the frame
  • Subtle surface changes → light feedback that adds realism without distraction

Configurable Rumble Zones

Choose how your rig comes alive.

The Road Rumble Sim supports multiple configurations depending on how immersive you want your setup to be.

“Motor count defines placement. Motor size defines intensity.”

2-Motor Setup (Left / Right)

  • Clean, simple directional feedback
  • Feel curbs and surface changes side-to-side
  • Great entry point with strong immersion gains

“Simple, effective, and a strong starting point.”

4-Motor Setup (Full Frame)

  • Front / Rear separation for traction awareness
  • Corner-based feedback (FL, FR, RL, RR)
  • More precise road detail and vehicle behavior
  • Ideal for competitive drivers and full immersion builds

“Full-frame feedback with front/rear and corner awareness.”

This scalable approach lets you start simple and expand into a fully immersive system over time.


Motor Size Options

Choose the right output level for your rig.

Standard Motors (Compact / Lighter Rigs)

  • Ideal for: aluminum profile rigs, lighter setups, smaller frames
  • Balanced output with clean, controlled feedback
  • Great for maintaining detail without overwhelming the rig

High-Output Motors (Large / Heavy Rigs)

  • Ideal for: heavier rigs, reinforced frames, larger cockpits
  • Stronger output to drive vibration through more mass
  • Maintains clarity and intensity on larger set ups and frames

What You Feel

This isn’t just vibration—it’s information.

  • Curbs & Track Edges – Directional hits based on where you contact
  • Road Surface Detail – Changes across different parts of the track
  • Engine & RPM Feedback – Deep, responsive rumble through the frame
  • Wheel Slip & Traction Loss – Front vs rear grip awareness
  • Gear Shifts & Impacts – Sharp, localized feedback

The result is a more intuitive driving experience where you react faster and drive more consistently.


Features

  • SimHub-powered real-time haptic feedback
  • 2 or 4 motor configurations (expandable)
  • Directional and positional vibration feedback
  • Tuned for road surface simulation
  • Adjustable intensity and effect profiles
  • Compatible with bass shakers / transducers and other tactile feedback systems
  • Plug-and-play integration with your rig
  • Designed to scale with your immersion ecosystem

Compatibility

Designed for use with SimHub.

Supports a wide range of racing titles, including:

  • iRacing
  • Assetto Corsa
  • Assetto Corsa Competizione
  • rFactor 2
  • Automobilista 2
  • Dirt Rally
  • And more through SimHub telemetry

Why It Matters

Speed is something you see.
Grip is something you feel.

With directional, multi-point feedback, Road Rumble gives you the same kind of spatial awareness real drivers rely on.


The Result

More immersion.
Better control.
A deeper connection to every lap.
