do i have to get a bigger rollbar if i get the 2Bennett setup?

I have a minor nit to pick with Luis' otherwise excellent post.

	>Now, about the sway bars... a car will tend to roll because the
center of
	gravity is above the tire contact batch.  That creates a torque
on the chassis
	during cornering that would make your car roll over if not
counteracted by
	something.<
Right.
	>  That something are the springs and sway bars.  As the outside
spring
	compresses, it is applying more force on that corner of the car
and as the
	inside spring expands, it is applying less force on the inside
corner.<
You are confusing cause and effect (or phrasing it such that others
might.)  The sideways torque on the car from the cornering force is
causing more force (weight) on the wheels on the outside of the turn and
less force (weight) on the wheels on the inside.  This difference in
weight can be easily seen in the effect it has of compressing the
outside springs and decompressing the inside springs.

	> Also, with the strut suspension on the
	4kq, there is a point where, if you continue compressing the
suspension, the
	camber begins to change towards positive and you want to avoid
this.  <
Right.  The reason you want to reduce body roll is to keep your
suspension in optimum position.  You are *not* reducing weight transfer
(changing the effects of cornering force on the tires) by doing so.  You
are only maintaining your optimum contact patch.  

Also, lowering your car (= lowering the center of gravity) will reduce
the sideways torque and reduce the weight transfer (which in turn
reduces the effect of the weight transfer, which is body-roll).

Finally, I've seen the 2Bennet setup on Glen's car, and there is no
duct-tape involved.  Changing ride height is very easy.  It's also
really nice that he can change his shocks without resorting to a spring
compressor, so it becomes an easy job.
