Toyota GR Supra Tuning Guide — Best A Setup
I've spent way too many hours tuning the Toyota GR Supra (2020) in Forza Horizon 6. Here's what actually works — stuff I've tested in online lobbies and Rivals leaderboards. The Toyota GR Supra is a RWD with 382 HP stock, and it sits naturally in A class. If you're reading this you probably already own one and want to stop getting gapped. Let's fix that.
Best Build Path — A 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 A
| 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 Toyota GR Supra
- 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 A
FH6 Tuning Tips for This Car
When tuning this car in FH6, start with the suspension and tires before touching the engine. Most players add power first and wonder why the car is undriveable. The optimal build order is: race tires, race suspension, race brakes, weight reduction (stage 1-2), then engine upgrades. The PI budget should be split roughly 40% handling, 40% power, and 20% drivetrain. For road racing, prioritize corner exit grip over top speed. For speed zones, sacrifice some handling for more power. The most common mistake is over-upgrading — leaving the car at 80-85% of max PI often gives the best balance and leaves room for event-specific tuning adjustments. Test every upgrade increment, not just the final build.
