Virginia FIA F4 iRacing Track Guide: Official Baseline Data
This guide is built from the exact Valor Official Baseline for Virginia International Raceway (VIR) — Full Course + 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: 16
Meaningful brake events: 7 of 16 turns
No-brake / near-flow sections: 9
Peak speed in the reference trace: about 142.5 mph
Telemetry-integrated reference time: approximately 1:47.60
Average turn-profile confidence: 100.0/100
Heaviest brake zones: Turn 1 100.0%, Turn 14 82.4%, Turn 12 78.3%
Largest recorded speed reduction: Turn 1, roughly 142.1 → 57.3 mph
Slowest mapped minimum: Turn 13 at about 56.2 mph in gear 3
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
The F4 reference at VIR has two completely different personalities. The major stops are serious — Turn 1 reaches 100% brake and drops from about 142 mph to 57 mph — but the high-speed middle of the lap is built around commitment rather than pedal activity.
Turns 8, 9 and 10 are the clearest example. The baseline carries roughly 134–135 mph through all three without a meaningful brake event. If you are losing time there, the first question should be placement, steering load and confidence, not how much later you can brake.
The other defining area is the sequence around Turns 12 through 14. Turn 12 uses a hard 78.3% brake event, Turn 13 falls to the slowest mapped minimum on the lap, and Turn 14 then becomes another major stop from roughly 142 mph. VIR rewards drivers who can switch quickly between flow driving and disciplined heavy braking without carrying one technique into the wrong corner.
Turn-by-turn baseline guide
Turn 1 — right
This is a major braking zone. The baseline begins the brake event at roughly 142.1 mph, peaks at 100.0% brake, reaches about 57.3 mph in gear 3, and exits the mapped segment around 92.3 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 2 — left
The reference uses no meaningful brake input here. It carries about 102.9 mph in gear 4 and builds to about 107.7 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 — left
This is a speed-management braking zone. The baseline begins the brake event at roughly 109.1 mph, peaks at 36.5% brake, reaches about 88.0 mph in gear 4, and exits the mapped segment around 93.7 mph. Brake release is complete roughly 47 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 — left
This is a firm braking zone. The baseline begins the brake event at roughly 101.4 mph, peaks at 78.0% brake, reaches about 65.3 mph in gear 3, and exits the mapped segment around 75.5 mph. Brake release is complete roughly 43 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 5 — right
The reference uses no meaningful brake input here. It carries about 75.9 mph in gear 3 and builds to about 83.4 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 6 — right
The reference uses no meaningful brake input here. It carries about 84.5 mph in gear 4 and builds to about 96.3 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
The reference uses no meaningful brake input here. It carries about 100.1 mph in gear 4 and builds to about 115.4 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 8 — right
The reference uses no meaningful brake input here. It carries about 134.0 mph in gear 6 and builds to about 134.5 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 9 — left
The reference uses no meaningful brake input here. It carries about 135.0 mph in gear 6 and builds to about 135.3 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 10 — right
The reference uses no meaningful brake input here. It carries about 133.7 mph in gear 6 and builds to about 133.9 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 11 — right
This is a light-brake speed-management corner. The baseline begins the brake event at roughly 134.9 mph, peaks at 7.2% brake, reaches about 123.2 mph in gear 6, and exits the mapped segment around 127.2 mph. Brake release is complete roughly 81 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 firm braking zone. The baseline begins the brake event at roughly 130.4 mph, peaks at 78.3% brake, reaches about 91.1 mph in gear 4, and exits the mapped segment around 91.1 mph. Brake release finishes essentially at the minimum-speed point, so braking and rotation are tightly linked.
Turn 13 — right
This is a speed-management braking zone. The baseline begins the brake event at roughly 78.6 mph, peaks at 32.7% brake, reaches about 56.2 mph in gear 3, and exits the mapped segment around 75.3 mph. Brake release is complete roughly 26 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 13 m after minimum speed, so exit preparation matters more than forcing the pedal early.
Turn 14 — right
This is a firm braking zone. The baseline begins the brake event at roughly 142.0 mph, peaks at 82.4% brake, reaches about 62.9 mph in gear 3, and exits the mapped segment around 72.3 mph. Brake release is complete roughly 32 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 15 — left
The reference uses no meaningful brake input here. It carries about 79.1 mph in gear 3 and builds to about 104.9 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 16 — right
The reference uses only a very small brake trace here (3.2% peak), so this behaves much more like a flow corner than a true braking zone. Minimum speed is about 100.5 mph in gear 4, with roughly 117.4 mph by the mapped exit. If you are making a large brake event here, check whether entry placement or the previous corner is forcing the extra correction.
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.
If your minimum speed is lower than the reference, look backward at brake timing, release shape and steering load before assuming the solution is simply to enter faster. If your minimum speed is close but exit speed is weak, inspect throttle timing and how much steering remains when power is applied. If you are braking in a reference flow section, determine whether the problem actually began in the previous corner.
