I recently put this configuration on my '83 Westy and it has greatly improved
handling. The back is stiff for the heavy Westy rear end and the front
(gr2's) seem to be a bit softer.  For $26 a pop they were a deal. A few weeks
after installation I put on new reinforced sidewall tires (Yokohama's) and
this really improved my crosswind stability. The PO had on a mixed bag of
185/14's. They are not 6-ply but have plenty of tread left if any one is
interested in them.
