Rear-Axle Motion Feedback System

A precision linear actuator for any rig model that translates simulator telemetry into rear slip, rotation yaw, and grip-loss cues.

The rear-axle body feedback simracing was missing.

The gap

Immersion is entertainment. Information is skill.

The gap is the missing rear axle.

In a real car, you feel rear rotation through the seat. Your body senses the yaw before your eyes fully confirm the slide. That early cue is what makes counter-steer feel instinctive instead of calculated.

On a static rig, that channel disappears. The car rotates on screen, but your body receives nothing. You can still drive fast, but you are reading the slide instead of feeling it.

Most motion systems focus on pitch and roll. But tilting a cockpit is not the same as braking, cornering, or weight transfer. Without sustained g-force, the brain cannot process vestibular input as useful vehicle information, so those movements often become noise: impressive at first, tiring later, easy to switch off.

TamedTail takes a narrower approach.

It restores the one cue sim racers can actually use: rear yaw. A compact linear actuator shifts the seat laterally in response to rear slip, giving your body the missing signal at the moment it matters, so the correction feels natural and instinctive.

Less motion. More information.

What you feel

More realistic physics need more physical feedback.

Modern simulators are more physically accurate than ever. This realism exposes a paradox: the better the physics, the larger the gap between a real driver feeling inertia through the car and a sim racer sitting in a static rig. Without rear inertia, simracers often drift toward safer, understeer-led driving instead of trusting rotation. TamedTail adds a low-latency rear-axle cue, helping your brain build trust and speed lap after lap. It adds a new level of situational awareness.

Intuitive by design.

TamedTail is tuned to feel natural, not distracting. The rear-axle cue triggers an instinctive vestibular response, so your body reads the movement before you have to think about it. The result is more flow, more trust, and less hesitation.

Build rear-axle muscle memory.

TamedTail gives your brain a physical training layer for each car, setup, and track condition. Lap after lap, you learn how the rear axle loads, rotates, and recovers grip. Over time, that muscle memory helps you drive closer to the limit with more confidence.

Pipeline

From physics data to physical trust.

The tech behind the feeling: live simulator data, adjustable motion, compact package, easy install, and real lateral displacement. Each step is designed to remove noise and preserve the cue that matters: what the rear axle is doing.

01

Simulator physics

Live simulator telemetry<10 ms simulator telemetry → motor movement

TamedTail turns high-rate simulator telemetry into a rear-axle cue faster than conscious reaction time. The result is a signal your body can start reading early, even when the movement is still subtle enough to stay below obvious physical distraction.

TamedTail app

Intensity controlPlug & play appNew sims added over time

Every driver feels motion differently. Start from the recommended 50% intensity setting, then adjust the cue until it feels natural and instinctive. Save track- and simulator-specific profiles. Available simulators: iRacing, Le Mans Ultimate, and Assetto Corsa. More integrations coming.

TamedTail is designed to sit beneath a rigid-frame sim rig and seat, below the driver mass. No modification to the rig is required. The front of the rig rests on custom rubber supports that allow the rotational movement the system needs, while in many setups the original feet can stay in place. Route the included cables, connect the controller, and drive.

Linear actuator

300 mm travelSupports 160 kg per axle18.5 kg system weight

The actuator supports up to 160 kg per axle and provides 300 mm of lateral displacement, more than enough for intense motion feedback. The 18.5 kg system sits beneath the rig and seat and is held in place by gravity. Front rubber supports require no installation either - just place them in the front corners beneath the rig.

Safety is not a feature — it is the architecture. Three independent layers (software limits, firmware watchdog, mechanical end stops) ensure the system cannot exceed its physical boundaries, even in component failure scenarios. This is aerospace and automotive defense-in-depth applied to simracing.

Track test

Real rear-axle feedback.

This track test shows the cue where it matters: watch the displacement at seat level and how it creates a new layer of physical perception for the rear axle. You can see the driver’s instinctive counter-steer reactions as the car moves underneath him.

“The reactions feel completely natural. Very informative. Sometimes even clearer than in a real car. It’s almost like cheating.”

Software

Install. Configure. Drive.

The TamedTail user app is the control centre for your motion system. It runs quietly in the background while you drive, reading simulator telemetry and translating rear-axle physics into the physical cue you feel. The Windows installer guides you through setup and keeps the app ready for future sessions.

Motion Signal

Plug and drive

Launch the app and it runs the required startup and safety checks before enabling motion. You can also set it to launch with Windows so it is ready when you are.

Your feel, your control

Adjust intensity from 0 to 100% in real time with the slider. Save separate profiles for each car and track so the motion always matches your setup. Toggle the overlay on or off with a single click - no alt-tab, no menus.

Always up to date

The installed app checks for new builds on startup and downloads them automatically. Every release is published with SHA-256 hashes you can verify before you run.
