Front Stub Axles
Height Adjustable Front Stub Axles
Problem: “The back slides/the kart oversteers going into the turns”
Solution:
Raise the front ride height i.e. lower
the front stub axles in the chassis by one
spacer at a time
Problem:
“There is too much steering or
front end bite on turn-in”
Solution: Lower the front ride height i.e.
raise the front stub axles in the chassis by one
spacer at a time.
Why?
Height adjustable front stub axles are an aid to achieving that “perfect” kart set-up. What is being achieved
when the front stub axles are lowered or raised is raising and moving back or lowering and moving forward
the kart’s “centre of gravity”(c/g).
When you lower the stubs in the frame you raise the kart’s front ride height. This raises the karts c/g. as well
as moving it further back. The effect on the kart will be to make it a little slower with its first-off reaction on
initial steering wheel input but from then on in the front will have more grip into the apex. The effect of
having moved the c/g. back will be to create more back end grip throughout the whole corner as well as
making the rear of the kart sit flatter.
Be careful of this as you might start feeling that your engine is going off, losing pull off of the turns but the
kart feels great. Wrong, the kart is sitting too flat through the corner. It’s not allowing a “differential effect”,
by lifting the inside (unloaded) back wheel off the track through the apex, pulling the engine down which
is trying to drive both back tyres through differing arcs on a fixed back axle.
Note: By raising the stub axle in the chassis you lower the kart’s front ride height achieving the reverse
of the above.
