Slamming my honda

Mr. Suspension, hope your there only have a few
more hours!!
Ok I'm buying some coilovers today and have the
100 year old question! Thought i was ready but  
need to know for sure. Don't really know all the
lingo so here we go. Ive got a 2007 Honda accord
sedan v6 and want lower her, it's a family hauler
that does A LOT of freeway driving so it needs to
be as smooth as possible no track time maybe a
freeway race once and a while! I would like to tuck
all four tires just a little using the stock rims and
tires from factory. Could anybody let me know
which coilovers would deliver the smoothest ride
for what I want to do. I was going for tein z flex or
buddy clubs  or function form or sci which would
be the smoothest thanks.
Mike
