5.2 - Adjustment of front wheels
5.2.1 - Adjustment of front tracking width
The adjustment of the front width is realized with several
spacers (spacer of 15 mm, and spacers of 5 mm for each stub
axle), and 2 hubs type (short hub: 90 mm or long hub: 100
mm). ●The wider the front is widened, the harder the
steering is hard.
●The narrower the front is narrows, the easier
the steering is easy.
●If you wish increase the grip of front, it sufce
to increase the width of the front with spacers.
Dry track
AB
It is advisable to adjust the front with a spacer of 15 mm (A) (1
spacer of 15 mm inside), and use the short hubs: 90 mm (B).
●With the front brake on your chassis, the
adjustment of the front is limited.
●No more than 20mm of spacers (A) (1 spacer
of 15mm and 1 spacer of 5mm), yoke side on
each stub axle if the kart is equipped with front
brake.
Wet track (without front brake))
AB
It is advisable to adjust the front with a spacer of 25 mm (A) (1
spacer of 15 mm and 2 spacers of 5 mm inside), and use the
long hubs: 100 mm (B).
Wet track (with front brake)
AB
It is advisable to adjust the front with a spacer of 20 mm (A)
maximum (1 spacer of 15 mm and 1 spacer of 5 mm inside),
and use the long hubs: 100 mm (B).
●With the front brake on your chassis, the
adjustment of the front is limited.
●No more than 20mm of spacers (A) (1 spacer
of 15mm and 1 spacer of 5mm), yoke side on
each stub axle if the kart is equipped with front
brake.
●Use longs hubs: 100mm (B) on wet track.
5.2.2 - Adjustment of front wheel height

● Place one 4mm spacer on top and one 4 mm + one 2 mm
spacer at the bottom.

Standard adjustment
● 1° Lower eccentrics place in negative camber position .
Increase the camber
● Same position as the “More negative” adjustment by
replacing the lower 1° eccentric by the 2° eccentric.
Reduce the camber
● Same position as the “More positive” adjustment. See
“Camber - More positive”.
●For high degrees eccentrics to be used in extreme
conditions, refer to the ITAKA web site
●Some negative camber generally improves the
performances of the kart.
Note: To facilitate adjustment of camber and caster, it is
possible to loose the screw (2). In this case be careful to
not lose the screw.
