Wheel arch liners?

[Joseph Cianciotti <jmc987@earthlink.net>]

WIth all this talk about mud flaps, I was wondering if anyone's ever 
installed those liners for the front wheel arches that I see in the Moss 
catalog.  Do they really make a difference?  I've thought about getting a 
set but feel it's just one of those 
"you-don't-really-need-it-unless-you've-installed-every-other-accessory-on-
your-car accessories."
