TIRES & BRAKES.
Before driving, make sure the tires and brake pads are in good
condition and show no signs of damages. The center nuts must be
tightened at 280Nm.
In normal conditions the tire pressure (warm) needs to be between
1.4 and 1.5 bar. Start driving at 1.2 bar, and let it off to the required
pressure after the temperature and pressure have risen.
In rainy or cold (T<?°C) conditions the tire pressure needs to be
between ?
Important!
Check wheel nuts before every session, make sure they
are tightened at 110Nm.
Adjust brake balancer static
Lift the car up with all four wheels off the ground. One person applies
the brake at such a force that another person can
just (so with a
certain amount of force)
turn the wheel on the front. The person in the
car must keep the same load on the brake pedal, while the second
person now turns the wheel on the rear. If the rear wheel is easier to
rotate; move brake balancer to R (rear), and try again. If front wheel
is easier to rotate; move brake balancer to F (front), and try again,
until the resistance front and rear is the same.
Always check the brake balance on the track while driving for fine
tuning it.
Adjust brake balancer dynamic
The brake balancer is adjustable step by step, by turning half rotation
each time. Do it while driving, with warm tires, on a straight part of the
track. Apply the brake and push until either front or rear wheels lock
(release brake immediately). If front tires lock up first, more brake
pressure is needed on the rear, so apply the brake balancer towards
rear (R), by half a turn each time, and try again, until the brake
balance is good. If rear tires lock up first, apply the brake balance to
the front (F). Brake balance adjustment (to the rear) should always be
done in rain conditions.

SETTINGS.
Engine (water) temperature should be kept between 78°C and 88°C.
Warm up until at least 70°C, and don’t run over 100°C. Engine
temperature is controlled by putting (duct)tape on the front airdam
gauze (B84N). At warm days no tape needs to be applied, at cold or
rain conditions use the amount of tape to get to the required
temperature range.
