[Tigers] Tigers Digest, Vol 9, Issue 141

[Rob Hogan]

Larry,
Adding the roll bar is a definite must do for track use and frankly as a
structural stiffening in road use.  I never seriously considered track runs
with just a hard top.  The questions in my planning are which
configuration: ether a full width bar, a double hoop pair of roll bars or a
slanted partial hoop bar with a reduced height diagonal on the passenger
side should be used to minimize weight while attaining roll over
protection; most likely where no passenger is present.
