I hope I don't go down in flames on this one, but I believe that the bar
JG is referring to is, in fact, 28 mm and that he would agree after checking
the parts bin.  Since torsional stiffness increases with the 4th power
of diameter, those 2 mm add up to a significant increase in roll stiffness.
The heavy bracket P/Ns are there in the fiche too. Don't forget to order
the rubber mounts and longer bolts that go with. Maybe you can
just reuse all the old stuff but I figure there must be a rationale for
the bracket change beyond the extra 2 mm.
