Why it is meta
Road Racing (S1, AWD, Stock V12): AWD V12 with active aero: forgiving and fast across S1 circuits, and stable under heavy braking.
In FH6, power is the biggest differentiator in road racing. Fill the car with as much horsepower as the PI budget allows, then tune the chassis to control it. You want strong corner exit traction, sharp turn-in, and stable braking. FH6 has more linear steering response and more forgiving braking than previous titles, so builds can be pushed closer to neutral balance. Aero is crucial at higher classes for maintaining grip through fast corners.
Upgrade priority
- Engine Swap or Power Upgrades Power is the biggest performance differentiator in FH6. More horsepower means faster straights and stronger exits, which add up to bigger lap time gains than any handling upgrade. Fill the car with as much power as the PI budget allows.
- Race Transmission (10-Speed) Unlocks individual gear ratio and final drive tuning. A 10-speed keeps the engine in its power band and cuts time lost between shifts, so matched gearing turns your power into lap time. Without it, extra power is wasted bouncing off the limiter or bogging down.
- Semi-Slick or Slick Tyres At S1 class you can afford slick compound. The extra grip lets you carry more speed through corners and get on the power earlier. The low-class off-road and rally tyre trick falls off here: race compounds pull clear.

Tuning
Tyres
| Setting | Value |
|---|---|
| Compound | Semi-Slick |
| Front Tyre Width | 275mm |
| Rear Tyre Width | 305mm |
| Front Pressure | 28.5 PSI cold |
| Rear Pressure | 28.5 PSI cold |
The standard competitive compound. These cold pressures climb to the optimal 32 to 34 PSI once warm (usually 1 to 2 laps). RWD runs higher front pressure for sharper turn-in; FWD higher still to reduce understeer. Widening front tyres is one of the most PI-efficient grip upgrades in FH6.
Gearing
| Setting | Value |
|---|---|
| Final Drive | 3.65 (assumes ~760 hp build) |
| 6-Speed Ratios | 2.97 / 2.07 / 1.6 / 1.3 / 1.1 / 0.96 |
| Strategy | Hit the rev limiter at the end of the longest straight |
The final drive is calculated for a ~760 hp S1-class build. On speed circuits lengthen it by 0.2 to 0.3; on tight technical circuits shorten it by the same. The ratio ladder is a close-ratio race pattern: if you run more than 6 gears, keep the same top and bottom ratios and space the extras evenly between them. Shorten 1st slightly if you bog off slow corners.
Alignment
| Setting | Value |
|---|---|
| Front Camber | -1.9 |
| Rear Camber | -1.4 |
| Front Toe | 0.0 to 0.1 out |
| Rear Toe | 0.0 to 0.1 in |
| Caster | 5.5 to 6.0 |
Moderate camber keeps the tyre surface on the road through body roll. A little front toe-out sharpens turn-in; keep rear toe-in small (0.0 to 0.1) because too much rear toe-in plants the rear and makes the car understeer. Caster scales with weight, but avoid going too high: excess caster loads the front tyres in a way that dulls turn-in and adds understeer.
Anti-Roll Bars
| Setting | Value |
|---|---|
| Front | 24.0 |
| Rear | 37.0 |
| Mech. Balance Target | 0.55 to 0.65 (aim 0.60) |
The split runs a soft front and stiffer rear to fight understeer: softening the front bar gives the nose more grip, and the stiffer rear helps the car rotate. Use the mechanical balance readout and aim for 0.55 to 0.65. To cure understeer, always soften the front rather than stiffening the rear, which only makes the rear looser.
Springs
| Setting | Value |
|---|---|
| Front Springs | 710 lbs/in |
| Rear Springs | 942 lbs/in |
| Front Ride Height | Minimum |
| Rear Ride Height | Minimum |
Springs are calculated from your car's weight and distribution, targeting a firm 2.6 to 3.2 Hz race frequency that stiffens with class. Modern FH6 tarmac tunes run stiff, so these are deliberately on the harder side for sharp response and body control. Minimum ride height lowers the centre of gravity for grip on smooth tarmac. If a value falls below your car's slider range, just set the lowest the car allows.
Damping
| Setting | Value |
|---|---|
| Front Rebound | 9.9 |
| Rear Rebound | 13.1 |
| Front Bump | 5.9 |
| Rear Bump | 7.9 |
Damping follows the spring frequency and the weight over each axle: the heavier end gets the stiffer damper. Bump is 60% of rebound. If the car feels harsh over kerbs, reduce bump on both axles first.
Aero
| Setting | Value |
|---|---|
| Front Downforce | 40% of total aero (if fitted) |
| Rear Downforce | 60% of total aero (if fitted) |
| Aero Balance Target | 0.40 to 0.45 |
The meta aero balance is 0.40 to 0.45, meaning roughly 40% front and 60% rear downforce. This gives a stable, rear-planted car at speed. Check the aero balance readout in the tuning menu and adjust sliders to hit this target. Maximum downforce at both ends is generally fastest for circuits.
Brakes
| Setting | Value |
|---|---|
| Brake Balance | 52% to 56% |
| Brake Pressure | 109% |
Front-biased brake balance prevents rear lock-up under heavy braking. FWD cars need more front bias as the rear is lighter. Pressure above 100% lets you brake later, which is where lap time is won; back it off if you lock up regularly. If the car spins under braking, move the balance further forward.
Differential
| Setting | Value |
|---|---|
| Front Accel | 20% |
| Front Decel | 0% |
| Rear Accel | 50% to 60% |
| Rear Decel | 15% to 25% |
| Centre Balance | 75% to 90% Rear |
Keep rear accel lock moderate (50 to 60%). A fully locked rear (100%) ties the driven wheels together and is a leading cause of corner-exit understeer, because a locked axle resists rotating under power and pushes the nose wide. Low front accel and zero front decel keep the front wheels free to steer. Keep rear decel low (15 to 25%) so the car turns in on lift-off. Push the centre balance as far rearward as the car will take (near 90%) for RWD-like rotation with AWD traction. If the nose still washes wide on exit, drop rear accel a few percent more; if an inside wheel spins up, raise it slightly.
