LFA_Nurburgring_U
For the Nürburgring Package, in order to further improve stability and corning speed,
exclusive shock absorbers, coil springs, stabilizers, high grip tires and aluminum
wheels that enhance body control and grip have been adopted.
During repeated test runs at the Nürburgring, controllability was increased across all
speed ranges from low to high, and a sense of oneness between the driver and the
vehicle was pursued.

■Suspension
In order to maximize aerodynamic and suspension performance, vehicle height, wheel
alignment, coil springs, stabilizers and the shock absorbers were finely tuned for the
Nürburgring Package.
Accordingly, an astounding level of both handling with high controllability and stable
body control has been achieved.

■Aluminum wheels
Through design changes, the
exposed area of the disc surface has
been expanded, improving brake
cooling performance.The grip of the POTENZA RE070 tires designed to perform best on dry roads.
Refrain from driving at high speeds on wet surfaces, such as on a highway in the
rain, as the Nürburgring Package is fitted with wide tires that have narrow tire tread
grooves that may increase the risk of hydroplaning.
The high-grip tread compound may crack during extremely cold temperatures.
Therefore, refrain from driving or storing the tires in temperatures of -4° F (-20°C)
or lower.
