The car’s chassis is the part subjected to the greatest loads during driving. This is particularly evident due to the transfer of body weight during fast cornering, heavy braking or decisive acceleration.
When cornering, weight transfer can cause one side of the vehicle to be subjected to a force up to three times greater than the other. The result is significant deformation and twisting of the chassis or bodywork, which can cause the tyres to lose grip.
Deformation and twisting of the chassis during cornering can cause undesirable handling characteristics, such as understeer and oversteer.
This Ultra Racing rear lower chassis reinforcement helps increase body rigidity around the rear axle.
