Arrow Kart, Owner'S Manual

Front End Alignment
On the track increasing Ackerman has the effect of increasing ‘turn-in’ of your kart. It forces the inside
front tyres to work more as well as increasing the mechanical chassis jack effect, or in other words will
increase the amount of lift off the track you’ll get with the inside back tyre through a corner while at
the same time increasing the mechanical grip of the outside back tyre. This is all good stuff but like all
good things in life too much can be bad!
On a track which offers a lot a fast sweeping corners with a fast corner leading onto the longest straight,
running a lot of Ackerman will only help kill your top end speed. It’s like setting the kart with toe-out
where the front tyres become dragging front brakes. On a track with lots of ‘stop, turn, go’ 180° type
corners, lots of Ackerman will really help. The kart will change direction quickly without overworking
the outside front tyre while the engine will be helped on acceleration out of the corner with the added
chassis jacking offering a greater differential effect (see “Height Adjustable Front Stub Axles”).
B) Adjustable Ackerman on the Steering Column
All Arrow karts offer adjustable Ackerman on the
steering column where the steering links are bolted
to the steering column ‘spade’. When supplied from
the factory, the steering links will be bolted on at the
outer two holes of the spade. Bolting both steering
links to the same central hole as offered on the spade
will decrease the amount of Ackerman the kart will
have, (see above for explanation of how Ackerman
principle works).
