Spa Toyota GR86 iRacing Track Guide: Official Baseline Data

This guide is built from the exact Valor Official Baseline for Circuit de Spa-Francorchamps — Grand Prix + Toyota GR86. 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 28 Valor data pack. The trace contains 9,830 recorded telemetry samples covering speed, brake, throttle, steering, gear, RPM and position. Turn numbering follows Valor's reviewed 18-turn map for this exact layout. Baseline speed is converted from meters per second to mph, and brake/throttle values are the recorded 0–100% channels. Conditions, setup, fuel, tires and 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: 18

• Meaningful brake events: 9 of 18 turns

• No-brake / flow sections: 9

• Peak speed in the reference trace: about 123.9 mph

• Telemetry-integrated reference time: approximately 2:43.44

• Average turn-profile confidence: 98.9/100

• Heaviest brake zones: Turn 17 100.0%, Turn 5 94.2%, Turn 12 86.6%

• Largest recorded speed reduction: Turn 17, roughly 123.9 → 42.7 mph

• Slowest mapped minimum: Turn 18 at about 39.4 mph in gear 1; the main braking event is carried in Turn 17

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. The average profile confidence is 98.9/100; Turn 6 is the one softer boundary at 80/100, while the remaining profiles are high confidence.

What the baseline says about Spa in the GR86

The GR86 reference makes Spa a momentum problem first and a braking problem second. Half of the mapped turns show no meaningful brake input, and the car stays above roughly 113 mph through the Turn 2–4 sequence. Because the GR86 has limited power compared with faster classes, unnecessary speed loss in those sections is expensive: once momentum is gone, the car cannot simply accelerate it back immediately.

The heavy stops are extremely clear. Turn 1 drops from about 101 mph to 40 mph with 86.1% brake. Turn 5 reaches 94.2% brake, and Turn 17 is the hardest stop in the baseline at 100% brake, falling from about 124 mph to 42.7 mph before the mapped Turn 18 minimum reaches 39.4 mph. By contrast, Turn 10 uses 67.2% brake but still carries about 96 mph. That makes Turn 10 a useful reminder that peak pedal pressure and minimum speed must be read together; a high-speed corner can be heavily braked without becoming a slow corner.

Turn-by-turn baseline guide

Turn 1 — right. This is a major braking zone. The baseline enters the braking event at roughly 101.1 mph, peaks at 86.1% brake, reaches about 40.2 mph in gear 1, and exits the mapped segment around 60.5 mph. Brake release finishes only about 2 m before minimum speed, so the reference carries the deceleration deep into the corner before asking the car to rotate. Full throttle follows almost immediately, about 3 m after minimum speed.

Turn 2 — left. The reference uses no meaningful brake input here. It carries about 114.0 mph into the mapped section, reaches about 114.0 mph in gear 5, and exits around 118.9 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 3 — right. The reference uses no meaningful brake input here. It carries about 119.2 mph into the mapped section, reaches about 113.5 mph in gear 5, and exits around 113.5 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 4 — left. The reference uses no meaningful brake input here. It carries about 113.3 mph into the mapped section, reaches about 113.2 mph in gear 5, and exits around 114.1 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 5 — right. This is a major braking zone. The baseline enters the braking event at roughly 119.3 mph, peaks at 94.2% brake, reaches about 68.8 mph in gear 3, and exits the mapped segment around 68.8 mph. Brake release finishes only about 6 m before minimum speed, so the reference carries the deceleration deep into the corner before asking the car to rotate. The mapped profile does not contain a definitive full-throttle point inside this corner boundary, so use the following trace to judge the exit rather than forcing an artificial throttle target.

Turn 6 — left. This is a light-brake speed-management corner. The baseline enters the braking event at roughly 71.7 mph, peaks at 10.8% brake, reaches about 68.6 mph in gear 3, and exits the mapped segment around 74.5 mph. Brake release is complete roughly 57 m before minimum speed, so most of the heavy deceleration is finished before the slowest point and the remaining job is rotation and balance. Full throttle arrives about 8 m after minimum speed, so getting the car pointed before committing to power is part of the reference shape. This profile carries 80/100 confidence, lower than the rest of this baseline, so treat the exact boundary timing here as a slightly softer reference.

Turn 7 — right. The reference uses no meaningful brake input here. It carries about 76.2 mph into the mapped section, reaches about 76.2 mph in gear 3, and exits around 87.9 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 8 — right. This is a firm braking zone. The baseline enters the braking event at roughly 104.9 mph, peaks at 79.8% brake, reaches about 54.1 mph in gear 2, and exits the mapped segment around 74.7 mph. Brake release finishes only about 4 m before minimum speed, so the reference carries the deceleration deep into the corner before asking the car to rotate. Full throttle arrives about 8 m after minimum speed, so getting the car pointed before committing to power is part of the reference shape.

Turn 9 — left. This is a speed-management braking zone. The baseline enters the braking event at roughly 84.6 mph, peaks at 30.6% brake, reaches about 77.5 mph in gear 3, and exits the mapped segment around 89.6 mph. Brake release is complete roughly 24 m before minimum speed, so most of the heavy deceleration is finished before the slowest point and the remaining job is rotation and balance. Full throttle follows almost immediately, about 1 m after minimum speed.

Turn 10 — left. This is a firm braking zone. The baseline enters the braking event at roughly 116.9 mph, peaks at 67.2% brake, reaches about 96.2 mph in gear 4, and exits the mapped segment around 101.7 mph. Brake release is complete roughly 22 m before minimum speed, so most of the heavy deceleration is finished before the slowest point and the remaining job is rotation and balance. Full throttle follows almost immediately, about 4 m after minimum speed.

Turn 11 — left. The reference uses no meaningful brake input here. It carries about 103.2 mph into the mapped section, reaches about 103.2 mph in gear 4, and exits around 111.8 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 12 — right. This is a major braking zone. The baseline enters the braking event at roughly 117.7 mph, peaks at 86.6% brake, reaches about 73.2 mph in gear 3, and exits the mapped segment around 73.3 mph. Brake release is complete roughly 24 m before minimum speed, so most of the heavy deceleration is finished before the slowest point and the remaining job is rotation and balance. The mapped profile does not contain a definitive full-throttle point inside this corner boundary, so use the following trace to judge the exit rather than forcing an artificial throttle target.

Turn 13 — left. The reference uses no meaningful brake input here. It carries about 75.1 mph into the mapped section, reaches about 75.1 mph in gear 3, and exits around 78.9 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 14 — right. This is a firm braking zone. The baseline enters the braking event at roughly 95.6 mph, peaks at 76.8% brake, reaches about 70.2 mph in gear 3, and exits the mapped segment around 79.6 mph. Brake release finishes only about 6 m before minimum speed, so the reference carries the deceleration deep into the corner before asking the car to rotate. Full throttle follows almost immediately, about 1 m after minimum speed.

Turn 15 — right. The reference uses no meaningful brake input here. It carries about 85.3 mph into the mapped section, reaches about 85.3 mph in gear 3, and exits around 103.0 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 16 — left. The reference uses no meaningful brake input here. It carries about 119.2 mph into the mapped section, reaches about 119.2 mph in gear 5, and exits around 120.5 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

Turn 17 — right. This is a major braking zone. The baseline enters the braking event at roughly 123.9 mph, peaks at 100.0% brake, reaches about 42.7 mph in gear 1, and exits the mapped segment around 44.2 mph. Brake release finishes only about 10 m before minimum speed, so the reference carries the deceleration deep into the corner before asking the car to rotate. The mapped profile does not contain a definitive full-throttle point inside this corner boundary, so use the following trace to judge the exit rather than forcing an artificial throttle target.

Turn 18 — left. The reference uses no meaningful brake input here. It carries about 44.6 mph into the mapped section, reaches about 39.4 mph in gear 1, and exits around 56.6 mph. Treat this as a momentum and positioning corner: if your trace shows a clear brake spike, first inspect line, steering load, and whether the previous corner left the car compromised before deciding you need more deceleration.

How to use this guide in Valor

Start with the three big anchors: Turn 1, Turn 5 and the Turn 17–18 final sequence. Compare the deceleration shape first, then minimum speed and throttle recovery. If your brake trace is similar but the exit delta keeps growing, the problem is likely rotation or throttle timing rather than where you initially hit the pedal.

Then audit the flow sections, especially Turns 2–4 and Turns 15–16. In the GR86, a small lift or unnecessary brake touch can create a loss that persists down the following straight. Valor's root-cause view is most useful here because it can separate the visible downstream time loss from the earlier input that actually caused it.
