The vehicle’s chassis is subjected to high loads during dynamic driving, particularly due to the transfer of body weight during fast cornering, heavy braking or acceleration.
When driving through a corner, weight transfer can cause one side of the vehicle to be loaded up to three times more than the other. This can cause considerable chassis flex or deformation and torsional twisting of the body, causing the tyres to lose grip.
Chassis deformation and twisting while cornering can cause undesirable driving characteristics such as understeer and oversteer. The Ultra Racing front anti-roll bar helps limit these body movements and improve the vehicle’s behaviour in corners.
- Design: front anti-roll bar
