3月に入り、少しずつ春の気配を感じるようになってきました。
とはいえ、サーキットの中はいつも通り真剣勝負です。
今日は少しマニアックなテーマです。
先日Instagramの投稿した画像に質問いただいた内容なのですが、「左右でキャンバー角を変えるのはなぜ？」についてです。
MINI-Zのセッティングで「キャンバーナックルを左右で変える」という話をすると、「え？左右同じじゃないの？」と言われることがあります。実はこれ、コースレイアウト次第で理にかなったセッティングなんです。
キャンバーとは、タイヤの傾きのこと。
・ネガティブキャンバー（タイヤの上が内側に傾く）
→ コーナリング性能が上がる
→ ただし直進安定性やタイヤ寿命はやや犠牲になる
MINI-Zでも0°、1°、2°、3°などのナックルがあります。
なぜ左右で変えるのか？という問いですが、答えはシンプルで「荷重が多くかかる側を最適化するため」です。
例えば、右回りの高速コーナーが多いコース。
この場合、強く荷重がかかるのはどちらでしょうか？
→ 左フロントタイヤです。高速コーナーでは外側タイヤに大きな荷重がかかります。
つまり右コーナーでは左フロントが最も頑張っているタイヤなのです。
実際のセッティング例
例：左：3°、右：1°
こうすることで「コーナリング中の接地を最適化」ロールした時に左タイヤがちょうど立つ状態になります。
結果、高速コーナーでの安定感が増します。
「直進安定性はなるべく維持」右側はキャンバーを弱めにすることでブレーキングやストレートの安定を確保。
「限界域がマイルドになる」いきなり「スパッ」と抜けにくくなります。これが一番大きいポイントです。
ですが、デメリットもあります。
・タイヤ摩耗が左右で変わる
・セッティングの再現性が少し難しい
・レイアウト変更に弱い
つまり常設コースやレイアウト固定向きのセッティングになります。
実はF1でも、コース特性によっては左右でアライメントを微調整します。つまり、左右非対称セッティングは「邪道」ではなく、「戦略」になります。マシンは左右対称でも、大体のコースは左右対称ではありません。だからこそ、セッティングも対称である必要はないと思っています。何が言いたいかというと、自分なりのセッティングを試して楽しんだもん勝ちです。

As we enter March, we can start to feel the first signs of spring in the air.
That said, inside the circuit, it’s always serious business.
Today’s topic is a slightly technical one.
It comes from a question I received about a photo I posted on Instagram:
“Why would you run different camber angles on the left and right?”
When you mention using different camber knuckles on each side in MINI-Z setup, people often respond with,
“Wait… shouldn’t they be the same?”
In reality, depending on the track layout, this can be a very logical setup choice.
What is camber?
Camber refers to the angle of the tire.
• Negative camber (top of the tire leaning inward)
→ Improves cornering performance
→ But slightly sacrifices straight-line stability and tire life
In MINI-Z, knuckles are available in 0°, 1°, 2°, 3°, and so on.
So why change left and right?
The answer is simple:
To optimize the side that carries the most load.
For example, on a track with many high-speed right-hand corners:
Which tire carries the most load?
→ The left front tire.
In high-speed corners, the outside tire takes the majority of the load.
So in right-hand turns, the left front tire is doing the hardest work.
Example setup
For instance:
Left: 3°
Right: 1°
By doing this:
Optimize contact patch during cornering
When the car rolls, the left tire stands more upright at the ideal angle.
As a result, stability in high-speed corners improves.
Maintain straight-line stability
Keeping less camber on the right side helps preserve braking performance and stability on straights.
Make the limit more progressive
The car becomes less likely to “snap” suddenly.
This is actually the biggest advantage.
Are there downsides?
Of course.
• Tire wear becomes uneven left to right
• Setup repeatability becomes slightly more complex
• It’s less adaptable if the layout changes
In other words, this approach works best on permanent or fixed-layout tracks.
In fact, even in Formula 1, teams may fine-tune alignment asymmetrically depending on track characteristics.
So asymmetric setups are not “wrong” — they are strategic.
The car itself may be symmetrical.
But most tracks are not.
That’s why I believe the setup doesn’t have to be symmetrical either.
What I really want to say is this:
Experiment with your own ideas.
Enjoy discovering what works for you.
In the end, the one who enjoys the process wins.
Thank you for reading until the end.
