Winton FIA F4 iRacing Track Guide: Official Baseline Data

This guide is built from the exact Valor Official Baseline for Winton Motor Raceway — National Circuit + FIA F4. It is not a generic track description and it is not reconstructed from internet braking markers. The numbers below come from the canonical baseline CSV, the reviewed Valor corner map and the corresponding turn profiles in the September 5 Valor data pack.

Turn numbering follows Valor's reviewed map for this exact layout. Baseline speed is converted from the recorded meters-per-second trace to mph. Brake and throttle are the recorded 0–100% channels. Conditions, setup, fuel, tire state and driving line can move the exact targets, so use the data as a measured reference rather than a command to copy blindly.

Baseline snapshot

• Mapped turns: 12

• Meaningful brake events: 9 of 12 turns

• No-brake / flow sections: 3

• Peak speed in the reference trace: about 124.6 mph

• Telemetry-integrated reference time: approximately 1:16.30

• Average turn-profile confidence: 100.0/100

• Heaviest brake zones: Turn 11 92.5%, Turn 3 89.8%, Turn 10 89.8%

• Largest recorded speed reduction: Turn 7, roughly 103.6 → 47.1 mph

• Slowest mapped minimum: Turn 9 at about 44.6 mph in gear 2

The integrated time is calculated from the reference trace's recorded position and speed because the distributed baseline CSV does not contain the simulator's lap-clock channel. Treat it as a telemetry-derived reference time, not an official iRacing timing result.

What the baseline says about this combination

Winton is much more brake-driven than VIR in the F4 reference. Nine of the 12 mapped turns show meaningful brake input, and several of those are very high-pressure events. That means the lap is less about one heroic braking point and more about repeatedly getting the car slowed, released and rotated without carrying unnecessary deceleration into the apex.

The biggest compression comes through Turns 7, 8 and 9. Turn 7 drops from about 104 mph to 47 mph, Turn 8 follows at roughly 62 mph minimum, and Turn 9 becomes the slowest mapped corner at about 45 mph. If the car is late or poorly positioned entering that sequence, the loss can cascade across multiple corners.

Turns 10 and 11 then demand two more strong braking events at roughly 89.8% and 92.5% peak brake. Winton rewards a driver who can make the heavy phase decisive, release the pedal early enough to rotate, and avoid turning every slow corner into a long coast.

Turn-by-turn baseline guide

Turn 1 — left

This is a firm braking zone. The baseline begins the brake event at roughly 124.5 mph, peaks at 71.8% brake, reaches about 88.6 mph in gear 4, and exits the mapped segment around 89.7 mph. Brake release is complete roughly 46 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle follows almost immediately after minimum speed; getting the car pointed early is central to the exit.

Turn 2 — right

The reference uses no meaningful brake input here. It carries about 91.8 mph in gear 4 and builds to about 96.2 mph by the mapped exit. If your trace shows a clear brake spike, first check line, steering load and whether the previous corner has left the car out of position.

Turn 3 — right

This is a major braking zone. The baseline begins the brake event at roughly 110.5 mph, peaks at 89.8% brake, reaches about 69.7 mph in gear 3, and exits the mapped segment around 80.1 mph. Brake release is complete roughly 46 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle follows almost immediately after minimum speed; getting the car pointed early is central to the exit.

Turn 4 — right

The reference uses no meaningful brake input here. It carries about 85.2 mph in gear 4 and builds to about 91.6 mph by the mapped exit. If your trace shows a clear brake spike, first check line, steering load and whether the previous corner has left the car out of position.

Turn 5 — right

This is a light-brake speed-management corner. The baseline begins the brake event at roughly 111.4 mph, peaks at 20.0% brake, reaches about 98.6 mph in gear 4, and exits the mapped segment around 99.0 mph. Brake release is complete roughly 58 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner.

Turn 6 — left

The reference uses no meaningful brake input here. It carries about 102.2 mph in gear 4 and builds to about 103.6 mph by the mapped exit. If your trace shows a clear brake spike, first check line, steering load and whether the previous corner has left the car out of position.

Turn 7 — left

This is a firm braking zone. The baseline begins the brake event at roughly 103.6 mph, peaks at 61.1% brake, reaches about 47.1 mph in gear 2, and exits the mapped segment around 61.4 mph. Brake release is complete roughly 25 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle follows almost immediately after minimum speed; getting the car pointed early is central to the exit.

Turn 8 — left

This is a speed-management braking zone. The baseline begins the brake event at roughly 76.1 mph, peaks at 31.7% brake, reaches about 61.6 mph in gear 3, and exits the mapped segment around 66.4 mph. Brake release is complete roughly 41 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner.

Turn 9 — right

This is a speed-management braking zone. The baseline begins the brake event at roughly 72.8 mph, peaks at 49.3% brake, reaches about 44.6 mph in gear 2, and exits the mapped segment around 75.5 mph. Brake release is complete roughly 28 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle arrives about 7 m after minimum speed, so exit preparation matters more than forcing the pedal early.

Turn 10 — right

This is a major braking zone. The baseline begins the brake event at roughly 107.2 mph, peaks at 89.8% brake, reaches about 58.5 mph in gear 3, and exits the mapped segment around 80.2 mph. Brake release is complete roughly 30 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle follows almost immediately after minimum speed; getting the car pointed early is central to the exit.

Turn 11 — left

This is a major braking zone. The baseline begins the brake event at roughly 114.5 mph, peaks at 92.5% brake, reaches about 63.1 mph in gear 3, and exits the mapped segment around 68.7 mph. Brake release is complete roughly 31 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle follows almost immediately after minimum speed; getting the car pointed early is central to the exit.

Turn 12 — right

This is a speed-management braking zone. The baseline begins the brake event at roughly 75.4 mph, peaks at 28.8% brake, reaches about 65.3 mph in gear 3, and exits the mapped segment around 85.4 mph. Brake release is complete roughly 24 m before minimum speed, so the reference finishes most of the deceleration before the slowest point rather than dragging heavy brake deep into the corner. Full throttle follows almost immediately after minimum speed; getting the car pointed early is central to the exit.

How to use this guide in Valor

The fastest way to use these numbers is not to memorize every speed before you drive. Pick one corner, complete a clean lap, and compare the trace.

At Winton, pay particular attention to whether a time loss begins at brake release rather than brake start. If you brake later but remain on the pedal longer, the car can arrive at minimum speed in the wrong position and cost more on exit than you gained on entry. Compare the shape of the full corner before chasing a single number.
