How deeply the engineers read your car — the hardest setting to nail in a setup, made visible.
FRONT
REAR
Indianapolis: the front "goes through" but won't bite.
Flat-out into Indianapolis, downhill, the front dives and the rear unloads — the bubble slides to the rear. The front turns in but won't bite: vague, on the edge of a snap. Not viable over 24 hours.
- What it reveals: the balance is at fault — too much load on the rear, front platform too soft.
- Typical conclusion: support the front (rake, ride height, ARB) to bring the bubble back to centre — sharper turn-in, stable at top speed.
- Live + logged: the pit wall tracks this bubble and the per-corner extremes by distance, so repeated anomalies surface and get corrected.

In the corner, the car rolls onto its outer tyres.
Through a fast right-hander the bubble swings right — load piles onto the outer tyres while the inside goes light. Too much roll and the car leans on two tyres instead of four: less grip, vague balance.
- What it reveals: a front-to-rear roll imbalance — one axle leaning more than the other.
- Lever: anti-roll bars, springs and ride height — keep all four tyres working through the corner.

Center of gravity: where the weight really sits.
We read the per-wheel loads and the car's mass and show the weight on each axle — plus a CoG marker that walks backward as you fill the tank, exactly like a corner-weight rig in the garage.
- Market-first: no other sim telemetry plugin computes weight-per-axle and center of gravity to guide a setup.
Center of pressure: the wind-tunnel number, computed.
The sim never gives you downforce — so we deduce it from ride-height drop and stiffness, and show the CoP migrating with speed: that reveals whether an imbalance is aerodynamic or mechanical.
- Market-first: as of 2026, no other plugin for iRacing, Le Mans Ultimate, RaceRoom, Automobilista 2 or rFactor 2 computes the center of pressure.
