🔧 Camber
The inward/outward tilt of a wheel viewed from the front. Negative camber (top leaning in) is normal.
More negative camber adds cornering grip but reduces straight-line contact.
What it actually does
Camber is how far the top of a wheel leans in or out when viewed from the front of the car. It exists because tyres do not stay flat to the ground when the suspension moves and the chassis rolls — a small amount of negative camber keeps more rubber on the road at the moment it matters most, mid-corner.
In practice
Negative camber means the top of the wheel leans inwards, and it is what nearly every setup runs. Adding negative camber generally increases cornering grip at that end of the car up to a point, past which straight-line traction and braking suffer because less of the tyre is in contact.
Worth knowing
Tyre wear tells the truth. If the inside edge is wearing much faster than the rest, you have more camber than the car is using.
