IQUIDS.
Fuel
The regular tank capacity is 70L, a
tank capacity of 90L is optional.
Saker strongly recommends
unleaded petrol with a RON
(Research Octane Number) of at
least 98 (AKI or PON: 93-94).
Lower octane numbers will suffer in
bad engine performances and
eventually damage to the engine.
Engine oil
Fill with 5,25L Kendall oil 5W50.
Advice: cold engine 1cm above
maximum on dipstick.
Important! Make sure the car
stands on a horizontal surface
while checking the oil level.
Gearbox oil
Fill with 5,25L Kendall oil 75W90.
Advice old dipstick: cold engine
between F and L on dipstick.
Advice new dipstick: cold engine
below L on dipstick.
Coolant
Fill with approximately 9 to 10L.
Advice: fill with coolant and fill it
up further during running the
engine. Take into account there is
air in the cooling system.
Braking fluid
se TRW brake fluid super DOT 4
or DOT 5.1
Important! Never mix brake fluids
with different DOT numbers! If not
sure about the DOT number of the
used brake fluid, refresh the oil of
the whole brake system.

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.
12
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.
Temperature Amount of tape
