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.

■Tires
Through the adoption of a high-grip
tread compound, the Bridgestone
POTENZA RE070 tires have
improved anti-wear performance
and heat resistance ready for circuit
driving while increasing grip.
Regarding the tread pattern, by
increasing the size of the tread
blocks on the outside shoulder of
the tires, where the most load is
applied, the contact patch has been
expanded and rigidity has been
increased.
Furthermore, by adopting a con-
struction with a highly rigid reinforc-
ing belt, the sidewall rigidity is
increased, ensuring linear response
and grip when pushed to the limits.
Tire expiration date
In order to preserve tire performance, we recommend periodic replacement of tires
every 6 years. The 4 digits on the sidewall can be read as follows:

■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.
