to move the driver seat. You should
be able to fully depress the brake
pedal with your knees slightly bent.
3 Adjust the height of the seat and the
position of the steering wheel. You
should be able to grip the top of the steering wheel with your elbows slightly bent
and your back at a comfortable angle.
4 If necessary, readjust the seat position.
5 Adjust the mirrors to ensure that you have a good view of the area behind the
vehicle.

Ideal driving position
An ideal driving position allows for smooth operational inputs and also helps to
reduce injuries in the event of a collision. Although the driving position employed by
racing drivers in competition offers maximum car control, it is not always practical for
use on public roads.
While the ideal driving position will vary depending on individual requirements and
driving conditions, please observe the following points in order to ensure a safe and
comfortable driving position:
■
■Seat slide adjustment
When sliding your seat back and forth, aim for a position that allows you to fully
depress the brake pedal with your knees slightly bent. Also, to ensure that you have
enough leverage to depress the brake pedal, make sure that your back rests firmly
against the seatback.
If your leg is fully extended to depress the brake pedal and a collision occurs, your
knee will not be able to help absorb any impact force. Instead, the full force of the
impact will be transferred to your lower back, possibly resulting in spinal injuries.
■
■Seat angle adjustment
When adjusting the seatback, aim for an angle that allows you to rest your back firmly
against the seatback with your hands gripping the top of the steering wheel and your
elbows slightly bent. Resting your back firmly against the seatback offers better body
support.
To maintain an adequate level of support, it is essential to make sure that your arms are
not over-reaching to touch the top of the steering wheel. Sitting too far away will force
you to lean forward when turning, compromising the support offered by the seatback.
Finally, make sure that the seatback is not reclined excessively, as this may result in
your body slipping under the seat belt in the event of a collision.
The seats in the LFA employ a racing bucket seat-inspired design and frames made
from CFRP (Carbon Fiber Reinforced Plastics) to ensure a highly rigid and supportive
construction.
To ensure that the seats are used to their maximum potential, always maintain an
appropriate driving position.

■Steering wheel adjustment range
The LFA has a tilt and telescopic steering column that allows you to manually adjust
the longitudinal and vertical position of the steering wheel.
The tilt fulcrum has been placed a significant distance away from the steering wheel
itself in order to minimize the change in steering wheel angle when adjusting its
vertical position. Minimizing the change in steering wheel angle prevents the top of
the steering wheel from moving too far away from the driver.
Meanwhile, the telescopic adjustment allows the steering wheel and column to be
moved as a whole so that the distance between the steering wheel and the paddle
shift switches remains the same.

■Suspension
The LFA is equipped with a double wishbone front suspension and multi-link rear
suspension.
The front suspension features two independent lower arms that shorten the offset of
the virtual kingpin axis from the wheel centerline along with a slightly negative kingpin
offset in order to ensure ample stability under braking. Furthermore, the low offset
between the kingpin axis and wheel centerline allows for excellent road compliance
and outstanding stability.

Regarding suspension adjustments:
The LFA is equipped with adjustable coil spring perches in order to allow for
any fine tuning needed to keep the geometry optimized at all times. Each LFA is
shipped from the factory with the suspension adjusted to the optimal settings.
