Ariel Atom V8 Tuning Guide — Best S1 Setup
I've spent way too many hours tuning the Ariel Atom V8 in Forza Horizon 6. Here's what actually works — stuff I've tested in online lobbies and Rivals leaderboards. The Ariel Atom V8 is a RWD with 500 HP stock, and it sits naturally in S1 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 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
| 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 Ariel Atom V8
- 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
