Handling problems & possible causes
This section will list various handling
problems & what might be causing those
handling problems. Please use this section
only as a general guide. You may not see the
same exact results as mentioned below. Other
component settings may mask changes made in
different areas. Adjustments in other areas
may be needed first before you see some of
the changes indicated below in certain
areas. All troubleshooting answers assume
the rest of the chassis is already set
correctly or close to being correct.

WHAT IS BUMP?
perfectly
correct, also known as "compression" a
breakdown is like this
at the right front--
adding bump will tighten entry and less will
loosen entry
at the left
front--adding bump loosens entry and
less will tighten entry
at the right rear
--adding bump will loosen your exit and less
will tighten exit
at the left rear--adding bump will tighten exit and less will loosen exit
