Anti-Roll Bar

An Anti-Roll Bar is used to control body roll whilst cornering. A higher Anti-Roll Bar setting will increase response and a lower Anti-Roll Bar setting will increase stability. A softer Anti-Roll Bar will increase the amount of body roll during lateral forces. This means you will need increased camber to optimise grip, 2° of body roll will need 2.0° of negative camber to maintain maximum tyre contact patch whilst cornering.

In Gran Turismo 7, the tyres have a lot of grip and a very small slip angle window compared to a real world tyre of a similar compound. Slip angle is the difference between the angle of the wheels and the angle of the tyre tread in contact of of the ground. The small slip angle will give an "on edge" feel when driving once you hit peak slip angle, instead of a gradual loss in grip. For these reasons, maximising vehicle response is the best way of improving performance. This has been discussed in 2 Tyre Slip Angle.

Both instances are under lateral load and notice the biggest difference at mid corner.

• Softer front Anti-Roll Bar and a harder rear Anti-Roll Bar generates oversteer.

• Harder front Anti-Roll Bar and a softer rear Anti-Roll Bar generates understeer.

Although a softer Anti-Roll Bar will reduce the "on edge" feeling when reaching peak grip, the increased time needed to turn the vehicle into a corner will render softer Anti-Roll Bars detrimental to performance.

In majority if not all cases, using 10 for both Anti-Roll Bar settings is the best starting point.
