Rear Wheel Hubs
Rear Wheel Hubs
Problem:
“Understeer from the apex and out of the corner”
Solution:
Replace the rear wheel hubs with shorter units.
Problem:
“There’s no traction/the kart is oversteering coming from the apex out of a corner”
Solution:
Replace the rear wheel hubs with longer units.
Why?
By increasing or decreasing the distance between the outside of the rear axle
outer bearings and the inside face of the rear wheel hub you are infect increasing
or decreasing the amount of “working” axle. In other words, the length of axle
between the kart’s main chassis rails and the wheel assemble that is left clear to flex
un-unhindered.
In the same way as altering the rear track width, reducing the amount of
“working” axle will make the rear bite into the track and sometimes provide
more rear grip. Instead of going to narrow and/or wide with the rear track,
the ability of changing to longer or shorter hubs is a major advantage in
trying to obtain the ultimate kart balance. Different length wheelhubs are
available and these can be utilised to further fine-tune your kart’s handling
to your individual liking
Note:
If your Arrow is fitted with a 40mm axle the wheelhubs incorporate a unique design with a wheel-
locating insert. Fit the insert if you have your wheelhubs over the end of the axle and remove the
insert if you want to slide your wheelhubs further inwards for a narrower rear track.
Important: To
remove the insert slide your wheelhub onto the axle and tap the insert against the end of the
axle until it falls out. When the insert is fitted ensure it is fitted fully into the hub before fitting
your wheel. If the insert is sitting against the end of the axle and protruding from the wheelhub
this will stop your wheel from fitting correctly and will cause the wheel to come loose.
