Eric;
Does this mean that the of-the-shelf roll bars won't do a good job if we
roll over during standard driving? (Assuming there is such a thing as a
standard rollover. And, if one gets a custom made roll bar,what's your
protection if you bring it down to half size as you mentioned you would do
for regular driving. And, lastly, there seems to be a bit of talk in this
group about racing. How do I find out about it? I'm in Portland ME. And
someone mentioned pylon racing. Any info about this?
Thanks.
