How the McLaren 570S GT4 Handles Braking

The McLaren 570S GT4 offers comprehensive braking control through three adjustable parameters: brake bias, brake pad compound, and ABS/TC/ESC settings. Brake bias adjustment is critical and should be mapped to an in-car control for real-time tuning, as values above 50% shift braking force forward, increasing front lockup tendency but improving stability under heavy braking. The car provides three brake pad compounds—Low offers maximum modulation with reduced initial bite, while Medium and High progressively increase friction at the expense of pedal feel.

Braking performance is deeply interconnected with suspension setup, particularly front compression damping and camber. Higher front camber values improve mid-corner grip but reduce longitudinal braking force, necessitating a rearward bias shift to compensate. Similarly, increased front bump stiffness accelerates weight transfer during initial brake application, sharpening turn-in response but potentially destabilizing the rear on rough surfaces.

For optimal braking stability, use the 'Track' ABS/TC/ESC setting which provides minimal intervention while preventing catastrophic lockups. The car's 1540 kg wet weight and twin-turbo V8 generate significant momentum, making trail-braking technique essential. Focus on progressive brake release through the turn-in phase rather than abrupt inputs, allowing the suspension to manage weight transfer smoothly while maintaining aerodynamic platform control.

Stop Guessing, Start Improving

Many drivers slam the brakes with all their strength, but the fastest modulate pressure, use the brake to rotate the car, and exit as fast as possible. Train that skill here.

3 Essential Setup Tips

Tip 1

Brake Bias

Brake bias controls front/rear brake force distribution. Start with 56-58% front for most cars. Engine placement matters: front-engine cars need more front bias (58-62%), mid-engine cars run balanced (54-58%), rear-engine cars need less (50-54%). Understeering under braking? Add 1-2% front bias. Rear feels loose in braking zones? Reduce front bias by 1-2%.

Tip 2

Know Your Car

Check if your car has ABS, traction control, or brake mapping. ABS allows later braking but can increase stopping distance—adjust activation threshold in setup. High-downforce cars brake later and harder at speed but lose grip quickly as downforce bleeds off. Low-downforce cars require earlier, progressive braking with more trail-braking to rotate.

Tip 3

Quick Fixes

Locking fronts frequently? Reduce front bias 1-2% or brake earlier with gradual pressure. Car won't turn in under braking? Increase front bias 1% and practice trail-braking deeper into corners. Rear unstable in braking zones? Reduce rear bias or use smoother pedal release.

Master Your Braking

Common questions about braking in this car. Practice these techniques in our free app.

What's the best brake bias for the McLaren 570S GT4?
Most cars work well starting with 56-58% front bias. Adjust based on behavior: if you're locking fronts frequently, reduce front bias by 1-2%. If the rear feels unstable under braking, increase front bias. Engine placement matters too—front-engine cars typically need more front bias (58-62%), while mid/rear-engine cars run more balanced (54-58%). Always adjust in small increments and test.

Does the McLaren 570S GT4 have ABS or traction control?
Check your car's setup screen for available driver aids. Cars with ABS allow later, more aggressive braking but may increase stopping distances. If ABS is available, you can adjust its activation threshold in setup—higher thresholds give more control but require smoother inputs. Cars without ABS require progressive brake application to avoid lockups. Practice threshold braking in our app to develop the muscle memory for both scenarios.

Why do my brakes lock up in the McLaren 570S GT4?
Brake lockups typically happen from: (1) Too much front brake bias—reduce by 1-2%. (2) Too aggressive initial brake application—practice progressive pressure buildup. (3) Trail-braking too deep into the corner—release brake pressure earlier. (4) Cold tires or brakes—take an extra warm-up lap. (5) Downforce loss at lower speeds—brake earlier and lighter through slow corners. Use our Hold Pressure and Threshold Braking exercises to build the sensitivity needed to stay just below the lockup point.

How late can I brake in the McLaren 570S GT4 compared to similar cars?
Braking points depend on: (1) Downforce level—high-downforce cars brake 50-100ft later than low-downforce cars. (2) Weight—lighter cars brake later but have less grip margin. (3) Brake size and cooling—larger brakes handle repeated heavy braking better. (4) ABS availability—ABS cars can brake slightly later. Start conservative and move your braking point later by 5-10ft each lap until you find the limit. The key is consistency, not just maximum lateness.

How can I practice braking in the McLaren 570S GT4?
Braking Lab offers free web-based exercises that work with any wheel/pedal setup—no download needed. Try Hold Pressure to develop steady brake application, Trail Braking to master corner entry, and Threshold Braking to find the lockup limit safely. Each exercise gives instant feedback and tracks your progress. Practice 10 minutes before your race session to build muscle memory that translates directly to the track.
