■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.

■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.

In order to further pursue emotive performance in the Nürburgring Package, a weight
reduction of the interior equipment has been achieved.
The adoption of full bucket seats and exclusive CFRP (Carbon Fiber Reinforced Plas-
tics) parts reduced vehicle weight and helped contribute to improved drivability. Addi-
tionally, the adoption of these interior parts raises the expectation of driving.
■Full bucket seats (Europe only)
In the Nürburgring Package, full bucket seats (RECARO RS-W) have been adopted
to secure a stable driving position across a variety of driving conditions.
For the frame, lightweight and high-rigid CFRP has been adopted, improving drivabil-
ity due to a vehicle weight reduction and achieving a high level of holding performance
even during sharp turns.
Additionally, while maintaining side support performance, the shape of the seats have
been optimized, increasing the ease of getting in and out of the vehicle and improving
daily usability of the vehicle when compar ed to those used on racing vehicles.

■Holding performance
Even during sharp turns, the full bucket seats hold the driver’s body without allowing
any body movement and support accurate steering operations and pedal work.
Also, by keeping one’s posture, eyepoint is maintained, making it possible to judge dis-
tances and respond to object recognition correctly.
With the Nürburgring Package, the full bucket seat’s high holding performance
enables a precise driving position to be held, allowing the driver to enjoy driving at
their will.
■Weight reductions
The weight applied to the center of the vehicle is reduced by adopting lightweight and
high-rigid CFRP for the seat’s frame and Alcantara * for the seat’s upholstery, con-
tributing to an improvement in driving performance.

Full bucket seats
[Adjustment]
Lift the lever beneath the seat to adjust the seat forward or backward.
[Maintenance]
The seat cushions can be removed.
Remove the seat cushions to clean away dust under the cushions.
[Label attached to the seat cushion]
The procedure for removing the seat lever is
written on the label located under the seat
cushion. Take care not to scratch the label
when cleaning.

■Maintaining the vehicle's interior*2
■Alcantara*1 areas
After wiping dirty surfaces with a dampened soft cloth, wipe away any remaining
moisture with a soft, dry cloth.
■CFRP/Satin finish metal accent areas
After wiping dirty surfaces with a dampen ed soft cloth or synthetic chamois, wipe
away any remaining moisture with a soft, dry cloth.
■Leather areas
Remove dirt and dust using a vacuum cleaner and wipe the surface with a dry, soft
cloth to remove any remaining moisture.

Removing and installing floor mats
Floor mats are not provided on Nürburgring Package models.
Vehicles with power seats: If installing floor mats, ensure that then only use LFA-
exclusive floor mats. Refer to the Owner's Manual for details and cautions regard-
ing installation.
Vehicles with full bucket seats: Do not install floor mats. If floor mats are installed, the
floor mat retaining hooks (clips) may interfere with the seat when the seat is
adjusted, preventing the correct seat position from being reached.
