2015 IGNITE K3 SET-UP
BASELINE SET-UP INFORMATION FOR THE IGNITE K3
WET CONDITIONS (CONT)
TIRE PRESSURE
Bridgestone YLP: 12-24 PSI cold. Track conditions and ambient temperature play a big
part in determining the correct tire pressures for any given run. As the track gets
increasingly wet, you will generally increase tire pressures to ensure the tires get to
temperature. The wetter the track, the less friction the tire is facing, therefore the less
heat it is generating. If you find yourself preparing for a track that does not appear to
be significantly wet, decrease tire pressures to 12-14 PSI in an effort not to over-cook
the tires during the run.
For short qualifying sessions, increase all pressures by 1-3 PSI in an effort to get the tires
to temperature sooner. For long races, start with lower pressures to keep the kart from
tightening up as the laps increase.
CASTER
Caster is another conditional tuning option that depends on the amount of rain the
track is retaining. Generally, you will want to increase the amount of caster you put
into the kart, as the track gets increasingly wet. You can utilize caster adjustments in
both the top and bottom of the spindle yolk to achieve the highest possible caster
levels. Be careful not to load too much caster if the track is merely damp, as you do
not want to put too much load on the tires and overcook them.
CAMBER
There is a delicate balance between front and rear grip levels during wet conditions.
You want the front to have more grip that usual, but not so much that it 'overpowers'
the rear end of the kart. Generally, you will start a rain set up with more positive
camber than your usual setting, thus increasing turn-in grip levels.
