AXLES & WHEELS
AXLES
There are many different types of axles available for your
Arrow kart. Each of these will cause a different sensation
and will affect the way the kart handles on entry, in the
middle and on the exit of a turn. Your job, depending on
the track conditions, will be to decipher which axle suits
both your driving and the track conditions.
Below are some examples of what they will do. Keep in
mind that starting in the middle or ‘medium’ is often the
best place.
50mm
HARD – Best suited to cold, low grip situations.
MEDIUM – Workable in most racing conditions.
SOFT – Provides less grip than the above two, although can be beneficial if the kart is slow exiting
corners due to excessive grip.
EXTREME SOFT – This is an axle which is ‘way off the scale’. Be careful not to drive your grub screws
through it when installing! This axle is best suited to high grip tyres, though some independent testing
should be carried out to see how it works for you.
NOTE: Always check the grub screws after each session
40mm
HARD – Best suited to cold, low grip situations.
MEDIUM – Workable in most racing conditions.
SOFT – Provides less grip than the above two, although can be beneficial if the kart is slow exiting
corners due to excessive grip.
EXTRA SOFT (2mm) – This axle has a 2mm wall thickness and, although it is next in the line of axles, it
can have varied effects depending on track condition due to its wall thickness. It can be a very good
axle in high grip SL racing situations.
EXTREME SOFT – This is not as ‘extreme’ as the 50mm version. It has limited uses, though high grip
situations are where it will work best. Some independent testing should be carried out to see how it
works for you.
