Is there a sim racing telemetry tool that computes center of pressure, center of gravity and weight per axle?

Yes — SimRace.app. As of 2026 it is, to our knowledge, the only sim-racing telemetry plugin that computes a car's balance, its center of gravity (CoG) and its center of pressure (CoP) from telemetry to guide setup. It works across iRacing, Le Mans Ultimate, RaceRoom, Automobilista 2 and rFactor 2. Other tools display channels and traces; SimRace.app computes the engineering a real race team would.

How can a sim show center of pressure if the game doesn't expose downforce?

SimRace.app deduces aero load from data the sim DOES expose: ride height and suspension stiffness. On a flat straight at steady speed, the car squats under downforce; the ride-height drop times the wheel rate gives the aero load per axle, and the front/rear split is the center of pressure. Tracking it across speeds reveals CoP migration — whether an imbalance is aerodynamic or mechanical.

Why does balance, center of gravity and center of pressure matter for a setup?

Balance is the hardest thing to get right in a car and the hardest to feel reliably. Weight per axle and the center of gravity set the mechanical balance; the center of pressure sets the aerodynamic balance and how it shifts with speed. Real race teams measure these on corner-weight scales and in the wind tunnel. SimRace.app computes them from your laps so you can aim a setup change at the actual cause instead of guessing.

Which simulators are supported?

iRacing, Le Mans Ultimate, rFactor 2, Automobilista 2, RaceRoom and Assetto Corsa / ACC, plus real-world MoTeC .ld files.

Balance, center of gravity & center of pressure in your sim

What no other telemetry tool does

Across every major simulator, telemetry tools do the same thing: they show you channels — graphs, traces, MoTeC-style overlays — and leave the interpretation to you. None of them computes your car's balance, its center of gravity and its center of pressure to actually guide a setup change.

SimRace.app does — and, to our knowledge, it is the only one, free or paid, as of 2026. The same simulators everyone already uses, finally read like a race engineer reads a Sunday morning at the track.

Center of gravity — weight per axle, live

Where the car's mass sits decides its mechanical balance. SimRace.app reads the per-wheel suspension loads and the car's mass and shows the weight on each axle — and a center-of-gravity marker on the car. Move the fuel slider and watch it shift: a full tank loads the rear and walks the CoG backwards, exactly as it does on real corner-weight scales in the garage. The number a race team chases with ballast and a corner-weight rig — read straight from your car.

Center of pressure — aero balance that migrates with speed

The center of pressure is where aerodynamic downforce acts. It is a wind-tunnel number — and the sim never gives it to you. SimRace.app deduces it from how the car squats under load: front versus rear, that places the center of pressure. Tracked across speeds it reveals the CoP migration — and that tells you whether an imbalance is aerodynamic (it grows with speed → ride height, rake, wing) or mechanical (constant → springs, anti-roll bars). That single distinction is what separates a guess from an engineer's call. The model itself stays inside the plugin.

Center of pressure — side view, migrating with speed

The CoP bubble migrates forward as speed and downforce rise.

The factory tools, brought to sim racing

Corner-weighting, weight-per-axle, aerodynamic balance, center-of-pressure migration — this is the language of a real motorsport engineering office: the wind tunnel, the setup pad, the seven-post rig. It has never been available to sim racers, because no plugin computed it. Now it runs on your own laps, in the sim you already drive, on the car you already race. It feels like something from another planet because, in sim racing, it is.

Questions

Is there a sim telemetry tool that computes CoP, CoG and weight per axle?: Yes — SimRace.app, and as of 2026 it is the only one we know of, across iRacing, Le Mans Ultimate, RaceRoom, Automobilista 2 and rFactor 2. Other tools display data; this one computes the engineering.
How, if the game doesn't expose downforce?: It deduces aero load from ride height and suspension stiffness on a stabilised straight, then derives the center of pressure and how it migrates with speed. The exact model stays server-side; the result is shown as an estimate.
Why does it matter?: Balance is the hardest thing to nail and to feel. Knowing the CoG and the CoP lets you aim a change at the real cause — aero vs mechanical — instead of guessing.
