This provides predictable handling characteristics during high speed cornering, acceleration and braking. Their low weight and good downforce make for excellent cornering and braking abilities. Providing Negative Camber improves the cornering performance. Understeer gradient is one of the main measures for characterizing steady-state cornering behavior. Grooved tyres were introduced in instead of racing slick tyres to reduce cornering speed. Rear loading also amplifies cornering weave tendencies. The brakes have a new ABS designed for high speed cornering. The wheelbase grew from to , giving the FD2 more stability during high speed cornering. This provides more constant suspension geometry under hard cornering. Puncture-sealant tires and cornering lights were new options. American technical standards contain provisions for front cornering lamps as well as rear cornering lamps. In addition, the headlights also function as a cornering light. This angle is very important for the cornering performance of the vehicles. There were also two changes implemented to the cars in order to reduce cornering speeds. The longer wheelbase for the longer boiler produced problems in cornering.
