Setup Apparatus
Measure tweak with the car sitting on a flat reference surface (such as a Flat
Setup Board offered by HUDY).
CHECKING FOR REAR TWEAK
Determine if the REAR of the car is tweaked by checking at the FRONT of the
car.
A9.1
Lift and drop the front end and rear end of the car a few cm’s to let the
suspension settle.
A9.2
Place a sharp tool
underneath the front end of the
chassis at its middle point, and
lift the front end.
If one front wheel lifts before the
other, the rear end of the car is
tweaked and may be adjusted by
rear spring preload.
A9.3
Adjust the preload on the rear
springs until both front wheels lift at the same
time.
Increase the preload on the rear spring
diagonally across from the front wheel that
lifted first, and decrease the preload on the
rear spring diagonally across from the front
wheel that lifted last. Adjust both rear springs
in equal but opposite directions, otherwise you
will change the rear ride height.
Example: If the front right wheel lifts first, increase the preload on the rear
left spring, and decrease the preload on the rear right spring by an equal but
opposite amount.
A9.4
Reconnect the rear anti-roll bar, and
check for rear tweak again by lifting the front
end of the car.
If one front wheel lifts before the other, the
rear anti-roll bar is tweaked.
Adjust the length of one or both rear anti-roll
bar pushrods until both front wheels lift at the
same time.
CHECKING FOR FRONT TWEAK
Determine if the FRONT of the car is tweaked by checking at the REAR of the
car.
A9.5
Lift and drop the front end and rear end of the car a few cm’s to let the
suspension settle.
