Hey James et. al.-
Since in stock one can only add/change the front sway bar would
it be worth while for me to look into this to try to prevent this kind of
roll:

What are the potential negatives to more front bar? I am still running
stock shocks as well but I do not imagine the shocks have much impact
on body roll, or do they?
Thanks for your thoughts,
Matthew
