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.

Accordingly, an astounding level of both handling with high controllability and stable
body control has been achieved.
