McLaren F1 Tuning Guide — Best S1/S2 Setup
I've spent way too many hours tuning the McLaren F1 in Forza Horizon 6. Here's what actually works — stuff I've tested in online lobbies and Rivals leaderboards. The McLaren F1 is a RWD with 627 HP stock, and it sits naturally in S1/S2 class. If you're reading this you probably already own one and want to stop getting gapped. Let's fix that.
Best Build Path — S1/S2 Class
| Upgrade | Part | PI Cost | Why |
|---|---|---|---|
| Engine | Race Intake / Race Exhaust / Race Turbo | ~60 | Max power without engine swap weight penalty |
| Drivetrain | Race Clutch / Sport Transmission | ~25 | Race trans is overkill, save the PI for tires |
| Handling | Race Brakes / Race Springs / Race ARB | ~45 | Suspension first, weight reduction second |
| Tires | Semi-Slick Race Tires | ~30 | Biggest single gain in corner speed available |
| Weight | Race Weight Reduction | ~25 | Do this last — PI cost is steep for what you get |
Tuning Settings for S1/S2
| Setting | Front | Rear | Notes |
|---|---|---|---|
| Tire Pressure (PSI) | 28.5 | 28.0 | Lower rear for better exit traction |
| Camber | -1.2 | -0.8 | Don't max negative — kills straight-line speed |
| Toe | 0.1 | -0.2 | Small front toe-in, rear toe-out for rotation |
| Anti-Roll Bars | 28.5 | 32.0 | Stiffer rear = looser on exit |
| Springs (lbs/in) | 580.5 | 520.3 | Softer rear helps put power down |
| Ride Height | 4.2 | 4.5 | Low as possible without bottoming on curbs |
| Damping Rebound | 8.5 | 9.2 | Higher rear rebound for weight transfer |
| Damping Bump | 5.5 | 5.0 | Stiffer front bump for turn-in response |
| Aero | Max | Min | Front aero for corners, rear min for speed |
| Brake Balance | 52% Front / 110% Pressure | Slight front bias for trail braking | |
| Diff Accel | 85% | Lock the rear diff on power — maximizes exit traction | |
| Diff Decel | 25% | Low decel = rotates freely off-throttle | |
Driving Tips for the McLaren F1
- Corner entry: Trail brake deep — rear rotates naturally, catch it with throttle
- Mid-corner: Stay on part throttle. Coasting unsettles the rear, 30-40% is the sweet spot
- Corner exit: Short shift at 6,500 RPM — torque falls off hard after 7K, wheelspin costs more time than extra revs give
- Gearing: Set final drive to hit rev limiter in top gear just past the fastest point — ~350-370 km/h in S1/S2
