The1974 Lancia Stratos HF Stradale is one of the most exciting rally cars to drive in Forza Horizon 6, but it can also be one of the hardest to control. The short wheelbase and mid-engine layout make the car incredibly agile, yet that same design can turn it into a spin machine on dirt if the setup is too aggressive.



A lot of players make the mistake of building the Stratos like a normal AWD rally car. That usually ends with snap oversteer, sudden spins over bumps, and frustrating corner exits. The key is making the suspension soft enough to absorb rough terrain while still keeping the rear stable under throttle.



After testing several different setups, this tuning approach works especially well for B-Class and lower A-Class dirt racing.



Start With the Right Upgrades



Before touching the tuning sliders, the Stratos needs the proper hardware installed. Without these upgrades, even a good tune will feel unstable.



Recommended Build

Conversions

AWD Drivetrain Conversion

Keep the stock engine for B-Class or balanced A-Class builds



The AWD swap completely changes how manageable the Stratos feels on loose surfaces. It still keeps the playful rally personality, but you gain much better traction on launches and corner exits.



Tires & Rims

Rally Tire Compound

Maximum rear tire width



The wider rear tires help calm the rear end during acceleration, which is extremely important for this car.



Drivetrain

Race Transmission

Race Differential



These parts give you the tuning control needed to properly balance power delivery.



Platform & Handling

Rally Springs and Dampers

Race Front Anti-Roll Bar

Race Rear Anti-Roll Bar

Race Weight Reduction



The rally suspension is especially important because the Stratos struggles on uneven terrain with stiffer road setups.



Tire Pressure Settings



For dirt racing, softer tire pressures help the car maintain grip over bumps and loose surfaces.



Front: 1.6 Bar / 23.0 PSI

Rear: 1.5 Bar / 21.5 PSI



Lower rear pressure gives the back of the car more stability under acceleration. Since the engine sits behind the driver, the rear already carries a lot of weight, so the softer setup helps keep the car planted.



Alignment Settings



The alignment setup is where the Stratos starts to feel alive without becoming uncontrollable.



Front Camber: -1.5°

Rear Camber: -1.0°

Front Toe: +0.2°

Rear Toe: -0.1°

Front Caster: 6.5°



The slight front toe-out sharpens turn-in, helping the car rotate quickly into dirt corners. Meanwhile, the small amount of rear toe-in reduces instability when getting back on the throttle.



This combination keeps the Stratos responsive without making it nervous.



Anti-Roll Bars



A common mistake with dirt tunes is running stiff ARBs. The Stratos actually performs better with softer settings because the suspension needs freedom to move independently over rough terrain.



Front ARB: 12.00

Rear ARB: 18.00



The softer front helps the car absorb bumps, while the slightly stiffer rear keeps body movement under control during quick transitions.



If the car still feels too twitchy, soften the rear ARB another click or two.



Springs and Ride Height



This is probably the most important part of the setup.



Springs



Set both front and rear springs close to the softest 25% of the available range.



The goal is compliance, not sharp handling. Dirt racing rewards stability and traction far more than instant steering response.



Ride Height

Raise the suspension to maximum

Lower it by 2 clicks afterward



This gives the car enough clearance for jumps and rough sections while avoiding excessive body roll.



The Stratos becomes surprisingly stable once the suspension can properly absorb terrain changes.



Damper Settings



The dampers help prevent the car from suddenly snapping sideways after hitting bumps.



Rebound Stiffness

Front: 5.5

Rear: 4.5

Bump Stiffness

Front: 2.2

Rear: 1.8



Keeping the rear slightly softer is important because the mid-engine balance can become unpredictable if the rear suspension reacts too sharply.



A good rule for dirt builds is keeping bump stiffness around 35–40% of rebound stiffness, which works very well here.



AWD Differential Setup



This is the setting that transforms the Stratos from difficult to genuinely fun.



Front Differential

Acceleration: 40%

Deceleration: 0%

Rear Differential

Acceleration: 70%

Deceleration: 10%

Center Balance

65% Rear



This setup keeps the car feeling like a classic rally machine instead of turning it into a boring AWD grip build. Most of the power still goes to the rear wheels, so the Stratos can rotate naturally through corners, but the front wheels help pull the car straight when exiting turns.



It gives you controlled slides instead of random spins.



How the Car Feels on Dirt



With this setup installed, the Stratos becomes much easier to trust at high speed. It still feels lively, but the unpredictable snap-oversteer is greatly reduced.



The car performs especially well on:



Technical dirt circuits

Mixed-surface rally routes

Tight mountain roads

Short acceleration-heavy tracks



It may not be the absolute fastest AWD dirt car in the game, but it is easily one of the most rewarding once tuned correctly.



Community Tunes Are Also Worth Trying



If you do not want to build the setup manually, the in-game Tune Browser has several strong community tunes available. Many players recommend creators like PaperHeartZero for stable dirt-focused Stratos builds.
