Main features of IF18-III
Driving stability has been greatly improved by refining various parts based on the data accumulated through many big races with the IF18-II.
In particular, the shape of the main chassis and the area around the rear bulk have been changed to increase rigidity of the chassis and provide stronger rear grip.
In addition, the layout of the rear stabilizer has been redesigned. The long reach sway bar, which exhibits relatively mild characteristics, has been laid out in a lower position for a more direct feel. The stabilizer effect can befelt more strongly and a more reliable setting is possible.
The rear shock stays have also been newly designed. The shock mounting angle and upper arm mounting position can be selected from a wide range.
Around the front, the structure around the lower arm end has been changed and hook-type aluminum spacers have been adopted to increase strength and at the same time make it easier to adjust the width of the vehicle. The wide shock stays, which were previously optional, are now standard equipment to increase response and keep the front tires from losing grip at the end of corners.
In addition, a new carbon battery plate with two fixed points on the front and rear has been newly adopted. The chassis flex is effectively incorporated to achieve smooth corneringwhile maintaining the high vertical rigidity of the main chassis.
Ventilated brake discs, which are especially important for GP racing cars, are equipped as standard. The disc is larger in diameter than conventional ones to provide stable braking power. The brake pads are made of heat-dissipating aluminum plates and Teflon pads for better control.
The clutch is newly designed with a f35 lightweight small-diameter flywheel to improve engine pickup. The clutch weight has also been newly designed to increase mass, allowing the driver to feel the throttle feel of fine spring adjustment.
