Forza Horizo​​n 5 – ビルド &チューニング ガイド

組み立てのヒント

コンバージョン

• エンジン
  • ストックエンジンを保持し、別のクラスにプッシュする場合にのみエンジンをアップグレード
• ドライブトレイン
  • 元のドライブトレインを維持する可能性が高くなります
• 願望
  • ターボなしでパワー目標を達成できるなら、そうしてください
  • ターボは最高出力を高めますが、回転数が高い場合に限られます
  • スーパーチャージャーは最大出力を低下させますが、全回転範囲で

エアロ

• フロント
  • できればフロント エアロなしでビルドしてみてください。ただし、アンダーステア​​になったら使用してください
• リア
  • ダウンフォースを調整できるので、ポイントが落ちるたびに装着してください

タイヤとリム

• タイヤコンパウンド
  • ラリー/オフロード/ドリフト
    • 関連するタイヤを使用する
  • ロードレース
    • AWD 車のタイヤのコンパウンドはそれほど重要ではありません
    • RWD 車の 1 つまたは 2 つのタイヤ コンパウンドのアップグレードは、通常は適切です
    • ライバルのレースでない限り、スリック タイヤの価値はほとんどありません
      • 雨やオフロードがある可能性があるため、セミリックが推奨されます
  • フロントタイヤ幅
    • アンダーステア​​を解消
  • リアタイヤ幅
    • リアのグリップを強化
    • 前面よりもアップグレードする価値がある
  • リム
    • これらを使用して PI を調整します (PI は車のランキング システムです。A クラスは 800 です)
  • ホイールの間隔
    • 間隔を空けた側で車がより安定しているように感じます
    • より安定感があるので、リアだけ間隔をあけてもOK
    • オーバーステア/アンダーステア​​のバランスを調整するために使用

ドライブトレイン

• クラッチ
  • クラッチ付きマニュアルではあまり関係ありません
• 送信
  • 個々のギアを調整する必要はほとんどないため、通常はスポーツ トランスミッションが最適です
• ドライブライン
  • 最終的な PI ポイントの調整に使用
• 差額
  • 0PI
  • スポーツには価値がない
  • レースにはレースを使用
  • ラリーやオンロードを伴うオフロードにはラリーを使用
  • 完全にオフロード専用のオフロードに行く (デューン ジャンパーとロック クライマー)

停止

• ブレーキ
  • あると便利です。約 90% の確率で利用する価値があります
• 一時停止
  • ハンドリングが向上し、チューニング オプションがアンロックされるため、レースに参加する価値があります
• ARB (アンチロールバー)
  • Extremely useful for fine point tuning
• Roll cages / Chassis reinforcement
  • Full rollcage is usually heavy and not worth it
  • Rule of thumb, for each class you upgrade your car over its original class, add one rollcage upgrade
    • ie. if you take a B-class to A-class add 1 chassis reinforcement
• Weight reduction
  • Forza rewards min/max so go all in or not at all
  • Power builds are usually favored on online racing
  • “Adding power makes you faster on the straights, removing weight makes you faster everywhere”

Engine

• Spend engine upgrades last
• Intake &exhaust first
• Oil &cooling
• Turbo &displacement upgrades for last
• Cams usually cost too much PI points
• Flywheel is a great PI adjuster

Final Upgrade Tips

• If you have made it to the end without max PI, go back and adjust little things like, Rims, tire width, Driveline, Flywheel.
• Focus your builds on first unlocking tuning options then getting right tires, transmission, suspension setup.
• If you have a lot of spare PI then go with brakes, clutch, adjustable aero.
• Spend final PI on reducing weight or focus on adding power.

Tuning Tips

General

• Locked tuning setups (Greyed out in tuning menu)
  • Means you do not have the required options unlocked in the upgrade menu
  • Look for the upgrades with the yellow unlock box
  • Not all cars will have the ability to make every tuning adjustment

Differential

• Acceleration
  • Front
    • Lower % preferred
    • Go for 10-50%
    • Low on track builds, high on rally builds
    • Higher setting =understeer
    • very important for FWD
  • Rear
    • Higher % Preferred
    • Go for between 50-90%
    • Higher power cars prefer higher of that range
    • Higher setting =more oversteer
• Decelerations
  • Front/Rear
    • Never set higher than acceleration setting
    • Usually go for 0%
    • Lower is more responsive but less stable
    • Higher is more stable with entering corners
• Center
  • Makes car feel more FWD or RWD
  • Set between 50-80%
  • Rally/Offroad is closer to 50%
  • Track is closer to 80%
  • 70% is great starting value for many cars

Brake

• Balance
  • Brake balance is reverse
    • Sliding to “front” gives more braking to the rear tires
• Pressure
  • Higher Values mean quicker locking/ABS engagement
• These settings have little effect so not a big deal to adjust

Aero

• Very unimportant on cars below B-class
• Front
  • Eliminates understeer, makes car feel more responsive
• Rear
  • More cornering grip
  • Can make car less responsive by adding understeer

• Usually end up increasing downforce all around
• The faster you go, the bigger affect downforce will have, if you want more grip give more downforce

Damping

• Rebound Stiffness
  • Stock is usually pretty good
• Bump Stiffness
  • Usually comes too stiff
  • Should be between 50-75% of rebound stiffness
  • Race suspension defaults to 63%
  • You typically want bump towards the low end only rasing this if you notice the car bouncing/unstable
• General Rule
  • If your rear end keeps sliding, increase front rebound and bump or reduce rear rebound and bump

Springs

• Springs
  • Front
    • Low front =oversteer
  • Rear
    • Low rear =Understeer
  • General
    • Used to adjust over/understeer
    • Heavier/lower car should have stiffer springs
    • Soft suspension is less responsive but more grippy
    • Stiff suspension is more responsive but more likely to loose grip
    • AWD/FWD
      • More likely for understeer so lower front stiffness a bit
  • Ride Height
    • General
      • Lower is better
        • Set as low as possible without bottoming out

ARB (Anti-roll bars)

• General
  • Controls entry+mid corner balance
  • Very noticeable on AWD+FWD
  • RWD cars
    • Aim for half way between soft and middle on front
    • Aim for stiff and middle on rear
  • Front
    • Low front will result in oversteer
  • Rear
    • Low rear will have understeer

Allignment

• Camber
  • When you are track racing camber is good
  • Race suspension usually gives too much so bump it down a couple in front &rear
  • Adjust via looking at the telemetry menu (more later on)
• Toe
  • General
    • Adjust sparingly
    • Toe out =oversteer, response
    • Toe in =understeer, stability
  • FWD/AWD
    • 0.1-0.2 front toe out to give a little oversteer
  • RWD
    • 0.1-0.2 rear toe in to keep rear stable in corner
• Caster
  • General
    • Higher caster adds camber while in a turn while not affecting camber on a straight
    • Keep between 4-7*

Gearing

• Final Gear
  • If you added power you’ll want to extend and go towards speed so the last line goes just past the end of the graph
• Individual Gears
  • High power RWD you may want to extend 1st &2nd to make wheelspin less likely

Tires

• Tire Pressure
  • General
    • No tire wear so this setting just adjusts grip/heat
  • Higher pressure feels more responsive and will loose grip quicker
  • Lower pressure less response, slower loss of grip
  • 26-35 psi for track
  • Higher front psi is preferred (about 2-3 higher in the front)

Fine Tuning Details

• General
  • You need a place to test tune, the race track is a good pace
  • Open Telemetry with T on pc
  • On XBOX go to your setting and switch ANNA for telemetry then down on D-pad

Telemetry Tuning

• Suspension
  • Go to the suspension menu of the telemetry
  • Fully pink is fully compressed/bottomed out, you don’t want that
  • (Car can bottom out without suspension bottoming out)
  • During stress the pink bar should be between 20-80%
  • If it is not moving much
    • Soften the suspension
  • If it is moving too much
    • Stiffen the suspension

• Camber
  • Go to the TIRES, MISC. menu
  • Watch the camber of outside tires
  • Never want to the go positive
    • Want a minimum of around -1 to -0.5
• Go to the Heat menu
  • Go to the Heat menu
• Inside of the tire should be the hottest right around the clear to yellow color
• The difference between the inside and outside of the tire should never be more than about 20*F preferred within 10-15*F
  • If more than 20*F then lower the camber
  • If outside is hotter than inside, add camber
  • If outside and inside is hotter than middle add tire pressure
  • If middle is hottest part of tire lower tire pressure

Troubleshooting

Oversteer/Understeer

• Corner entry
  • Understeer (A little bit of corner entry understeer is normal)
    • Adjust tire pressure
    • Lower front springs / ARBs
    • Raise toe out
    • Raise Front downforce
    • Lower differential deceleration lock
    • Raise front bump
    • Lower front rebound
    • If during braking specifically
      • Move more brake bias towards the rear of the car
        • (Move the slider towards front)
  • Oversteer
    • Raise front springs / ARBs
    • Raise toe in
    • Raise differential deceleration lock
• Mid Corner

  • Adjust final gear

Conclusion

Big thanks to HokiHoshi where I learned this information from. Here are his videos of the subject where he goes more in dept but I just created this form as these are the notes/key points from his videos.
