Drive your run

Stage → three ambers → green.
Press W on green or release the transbrake.

Launch RPM 3,500 RPM

THROTTLE 0%

Hold W / ↑ to feed in power; release to lift.

CLUTCH PEDAL 0%

Hold C to disengage; release gradually to engage.

Default: press W on green; pressing it early is a red light. Hold C to disengage the manual clutch; release it to engage gradually. In transbrake-release mode, hold Space for the brake and launch RPM; keep W held for throttle. Releasing Space after green launches in one motion. Releasing early is a red light. Shift hint begins at 5,500 rpm. Hold C until the clutch meter is nearly full, then shift with Shift / X. Shifts without the clutch are rejected. Aim for the bright green perfect-shift band at 6,400–6,600 rpm; 6,200–6,800 rpm is still a good shift. Over-rev upshifts are allowed but rougher. Peak torque: 300 Nm at 4,300 rpm. Shift timing changes torque transfer and rear-tire upset without stopping forward power. Hold W to roll into the throttle; release it to lift. Throttle builds and falls at a fixed rate through a smooth, progressive response map. Rear-tire slip ratio compares wheel-surface and road speed, with low-speed regularization to avoid division by zero. High launch RPM can overwhelm grip. Distance displays in metres.

VEHICLE PRESETS Prototype

Reference presets use published stock gear ratios/final drives and tire-code static-radius estimates. Mass includes a driver estimate for the BRZ. Engine curves, limiter behavior, and power delivery remain simplified.

Engine power · crank HP 197 hp

GEAR SPEED GRAPH Drag an endpoint to tune

MPH runs left to right; RPM runs bottom to top. Each gear has its own rising line from 0 RPM to redline. Drag a 7,000-RPM endpoint left or right to tune that ratio. Numeric inputs below also work by keyboard.

WHEEL SPEED VS GROUND SPEED Above diagonal = wheel overspeed

Ground speed is chassis speed. Driven-wheel speed is wheel rotation converted using tire radius. The diagonal marks equal speeds; divergence shows slip.

Tune power, mass, clutch capacity, and grip live; each changes the simulation immediately, including during a run. The 650 Nm default clutch can slip at high engine torque; a higher rating isolates the tire limit. Grip scales the modeled tire force from 0.1× to 2× the dry baseline. The ET figures use the calculator's empirical cube-root formulas, not the live tire simulation. They are not validated performance predictions; parts and weather effects are not modelled yet. Choose 1–10 forward gears and tune each active ratio from 0.30 to 5.00 before staging; transmission settings remain fixed during a run. Use progressively lower ratios in higher gears to make RPM drop on upshifts. Higher numeric ratios multiply engine torque more; lower ratios provide taller gearing.
