Mercedes-AMG GT3 2020
Braking numbers for the Mercedes-AMG GT3 2020 in iRacing, worked out from its grip estimate. Open any example in the Brake Planner to change the speed or corner.
Example braking zones
Fastest apex speed for each corner and the braking it takes to get there, assuming a corner arc of 100 m.
| Corner | Entry | Apex | Brake before apex | Time | ABS at 100% |
|---|---|---|---|---|---|
| Fast sweeper | 220 km/h | 170 km/h | 51 m | 0.96 s | after 9 m |
| Medium 90° corner | 200 km/h | 116 km/h | 69 m | 1.65 s | after 14 m |
| Hairpin after a long straight | 240 km/h | 85 km/h | 119 m | 2.84 s | after 14 m |
How to brake in the Mercedes-AMG GT3 2020
GT3 cars make real downforce, so they can take more pedal at 250 km/h than at 120 km/h. The planner shows this as the zone where holding 100% triggers ABS: the pedal has to ease off as speed drops even before you turn in.
Adjustable ABS and brake bias change the feel a lot between setups. Use the planner for where to brake and how the pressure should fall, then fine-tune the tolerance to your setup.
- Brake hardest at the top of the zone where the aero helps most.
- Trail the pedal to the apex in slow corners to keep weight on the front tyres.
- Fast corners need less trailing; the aero holds the car.
In a 90° corner at 200 km/h this means braking about 69 m before the apex and trailing the pedal down to 7% by the apex.
