Manual · Live
The /live page is your phone-propped-next-to-the-TV dashboard: real-time chassis state while you drive. The instrument cluster runs across the top; four corner panels sit around a center column. Each corner shows per-tire grip plus that wheel's spring and damper; the center column carries your inputs, the chassis attitude and power readouts, and the G-G dot.
G-G scatter · chassis
Round disc at the foot of the center column. Plots the car's instantaneous lateral G against longitudinal G — the so-called "friction circle" or "G-G plot," a pro-tool standard. The scatter cloud shows the envelope of how the car has been driven over the last ~20 seconds.
- X axis — lateral G. Left of center = cornering left; right = cornering right.
- Y axis — longitudinal G. Up = braking, down = accelerating. Matches the in-game G meter's convention (force on the driver).
- Inner dashed ring at 1 g, outer rim at 2 g.
- Amber dots — last ~20 s of history, fading from old (faint) to recent (brighter). ~200 dots, decimated to ~10 Hz so density carries the shape.
- Bright green dot — current instantaneous position. Updates at 60 Hz.
- Lat · long readout in the corner, in g.
| Smooth arc from top to side | Trail-braking — releasing brake as steering loads up. |
| Vertical line (top-to-bottom) | Straight-line braking + acceleration without cornering. |
| Horizontal blob | Sustained cornering with neither throttle nor brake (coast / steady-state). |
| Cloud fills the whole disc | Aggressive driving using all of the available envelope. |
| Tight near-center cluster | Smooth / cautious / cruising lap. |
| Cloud only on one side | Mostly turning one direction (a tight infield, hairpin loop, etc.). |
Friction circle · per tire
Same idea as the chassis G-G scatter, but plotting slip at one tire rather than acceleration at the whole car. Answers "is this specific tire past its grip limit right now?"
- X axis — slip angle (lateral). Negative = slipping one way, positive = the other.
- Y axis — slip ratio. Up = lockup (wheel slowed past road speed, braking too hard), down = wheelspin (wheel turning faster than road, accelerating past grip).
- Dashed inner ring at 0.7 — the "working zone" boundary. Inside = under-worked, outside = engaged in the grip envelope.
- Solid outer ring at 1.0 — friction limit. Outside this ring the tire is past grip; the Past grip chip lights up.
- Amber trail — recent ~0.5 s of slip.
- Center dot color — reflects the combined-slip value (greens through amber to red as you approach the limit).
| Dot stays inside the 0.7 ring | Tire under-worked at this moment — not at the grip limit. |
| Dot sits between the 0.7 and 1.0 rings | Working in the grip zone — what you want most of the time in a corner. |
| Dot passes outside the 1.0 ring | Past grip — the Past grip chip flares; could be intentional (drift, rally) or unwanted. |
| Trail stretches up | Braking past grip on this tire — lockup. The Lockup chip will follow. |
| Trail stretches down | Wheelspin under power. The Wheelspin chip will follow. |
| Trail stretches left or right | Lateral slip in that direction — the tire's sliding sideways rather than gripping. |
Spring & damper · per corner
Two different things share this strip, and they're tuned separately. The coil shows spring travel — where the suspension is sitting right now (a position). The bar beside it shows damper velocity — how fast it's moving (a rate). The spring is set by spring rate and ride height; the damper is set by bump and rebound stiffness. Same corner, different levers — hence the two labels, each linking to its own /tune page.
- SPRING coil — anchored at the base (the wheel on the road). As the corner loads, the top (chassis) cap descends and the coils bunch toward the bottom — the body squatting onto the wheel.
- Dashed line at the top — the full-droop reference. The gap between it and the coil's top is how far this corner has travelled.
- Coil color — green normal, amber past 80 % travel, red past 95 %. The red band at the base is the bump stop; the whole coil pulses when bottoming. The cm readout below is travel.
- DAMPER bar — zero in the middle. Rebound fills up (REB, spring extending), bump fills down (BMP, spring compressing). The mm/s readout is signed: + = bump, − = rebound.
- Bar color & ticks — faint ticks mark 25 and 50 mm/s. slow < 25, medium 25-50, fast > 50 mm/s (kerb hits, rapid weight transfer). Lightly smoothed so it's readable rather than strobing every frame.
| Coil near full length, top near the dashed line | Light load / droop — corner unloaded (cresting, inside wheel mid-corner, braking-unloaded rear). |
| Coil bunched, color amber/red | Heavy compression — weight piled on this corner; red means near the bump stop. Consider spring rate / ride height. |
| Bar mostly small / near center | Slow damper movement — smooth surface, steady-state corner. Where you want to live most of the time. |
| Bar slamming to the fast zone | Fast damper events — kerbs, bumps, sharp transitions. Bump vs rebound bias points at bump vs rebound damping. |
