FH6 Beginner Tuning: Copy-Paste Recipes for Every Class

Tuning in FH6 looks like calculus if you've never done it. Tire pressure, camber angles, gear ratios, differential settings — the tuning menu has 26 sliders and most of them change things in ways that aren't obvious until you've tested 50 different values. I've done that testing. Here are the exact numbers to plug in for a car that handles well in every class. These aren't world-record leaderboard tunes — they're "my car stops spinning out in corners and I can actually win races" tunes. Five minutes per car, guaranteed to work.

Universal Rule: AWD Conversion First

Before you touch any tuning slider, go to the Upgrades tab → Drivetrain → Drivetrain Swap → AWD. AWD cars accelerate faster out of corners, don't spin out under power, and are roughly 2 seconds per lap faster on average across every track type in FH6. The only exception is dedicated drift builds (RWD is correct for drifting). For everything else — road racing, dirt, cross country, speed zones, danger signs — AWD is the right answer. The drivetrain swap costs about 50K credits per car and adds roughly 30 PI. Budget for it, then tune.

S2 Class (901-998 PI) — Grip Build for Hypercars

Use on: Koenigsegg Jesko, Bugatti Chiron, Mosler MT900S, Rimac Nevera, any hypercar.

• Tire pressure: 28.0 front / 28.0 rear (low for max grip, S2 cars need it)
• Gearing — Final drive: 4.10 (around 4.0-4.2 depending on the car's top speed; lower for speed builds, higher for handling circuits)
• Alignment — Camber: -2.5 front / -1.5 rear
• Alignment — Toe: 0.1 front / -0.1 rear
• Anti-roll bars: 30.0 front / 30.0 rear (max stiffness for the stiffest springs)
• Springs: 650 front / 550 rear (stiff, S2 cars are heavy and fast)
• Ride height: minimum (lowest possible, aero benefit at speed)
• Damping — Rebound: 9.0 front / 8.0 rear
• Damping — Bump: 5.0 front / 4.0 rear
• Aero: max downforce front, second-to-max downforce rear (slightly less rear for speed)
• Differential: 55% accel / 0% decel (front) | 65% accel / 15% decel (rear) | 70% balance to rear

S1 Class (801-900 PI) — Balanced Road Build

Use on: Nissan GT-R, Ferrari FXX-K Evo, McLaren Senna, any S1 supercar.

• Tire pressure: 28.5 front / 28.5 rear
• Gearing — Final drive: 4.30 (S1 cars have less power, shorter gearing helps acceleration)
• Alignment — Camber: -2.0 front / -1.0 rear
• Alignment — Toe: 0.1 front / -0.1 rear
• Anti-roll bars: 28.0 front / 26.0 rear
• Springs: 550 front / 450 rear
• Ride height: minimum
• Damping: 8.5 front / 7.5 rear (rebound), 4.5 front / 3.5 rear (bump)
• Aero: max front, middle rear (3/4 of the way up)
• Differential: 50% accel / 0% decel front | 60% accel / 12% decel rear | 65% rear balance

A Class (701-800 PI) — All-Purpose Workhorse

This is the most popular online class and the most competitive. Use on: Subaru WRX STI, BMW M3, Honda NSX, Nissan Skyline. This recipe prioritizes corner exit speed over top speed — you win A-class races by carrying speed through corners, not by having the highest straight-line speed.

• Tire pressure: 30.0 front / 30.0 rear (higher than S1/S2 because A-class tires have more sidewall)
• Gearing — Final drive: 4.50 (short gears, you won't hit 350 km/h in A class and you don't need to)
• Alignment — Camber: -1.5 front / -0.8 rear
• Alignment — Toe: 0.0 front / -0.1 rear (minimal toe for tire preservation)
• Anti-roll bars: 24.0 front / 22.0 rear
• Springs: 450 front / 380 rear
• Ride height: minimum minus 2 clicks (slightly up for bump absorption)
• Damping: 7.5 front / 6.5 rear (rebound), 4.0 front / 3.0 rear (bump)
• Aero: adjustable rear wing at 2/3 of max, front splitter at max if available
• Differential: 45% accel / 0% decel front | 55% accel / 10% decel rear | 60% rear balance

B Class (601-700 PI) — Grip Over Power

B-class races are won by not braking. Use on: Mazda MX-5, Honda S2000, Toyota Sprinter Trueno, any light RWD car converted to AWD.

• Tire pressure: 32.0 front / 32.0 rear
• Gearing — Final drive: 4.80 (B-class cars need short gears to stay in the power band)
• Alignment — Camber: -1.0 front / -0.5 rear
• Alignment — Toe: 0.0 front / 0.0 rear
• Anti-roll bars: 20.0 front / 18.0 rear
• Springs: 350 front / 300 rear
• Ride height: middle (B-class cars on bumpy roads need clearance)
• Damping: 6.5 front / 5.5 rear (rebound), 3.5 front / 2.5 rear (bump)
• Aero: minimal or none — B-class cars don't go fast enough for aero to matter much
• Differential: 40% accel / 0% decel front | 50% accel / 8% decel rear | 55% rear balance

General Tuning Tips

• Test before racing: After applying a recipe, drive the car for 2 minutes. Every car has slightly different weight distribution and these base tunes assume roughly 55/45 front/rear weight balance. Adjust spring stiffness up or down based on whether the car understeers (softer front springs) or oversteers (softer rear springs).
• PI budget: These recipes assume you've spent roughly half your PI on handling (tires, suspension, weight reduction, aero) and half on power. If your car is already above the class PI limit after installing AWD, remove engine upgrades before handling upgrades — a well-tuned 701 PI car beats a poorly-tuned 800 PI car every time.
• Differential cheat sheet: Higher accel % = more rear grip on corner exit but more understeer mid-corner. Higher decel % = more stability under braking but less rotation into the corner. 0% front decel is intentional — it lets the front wheels rotate differently under braking for better turn-in.
• If the car still spins: increase rear downforce, decrease rear tire pressure by 2 PSI, or decrease rear anti-roll bar by 2 clicks. Those three changes fix 90% of oversteer problems.
