Re: suspension question

["Al Floer" <cybercord@xxxxxxxxxxx>]

To All,

I had my M Roadster springs and shocks repleaced with H&R / Koni's SA's.
The cutting involved , to bew able to use the original strut housing is the
bent over part of the strut that holds the shock in the housing.  What had
to be done is this fold over part had to be cut pff to get the cartridge out
of the strut..  To hold the new Koni cartridge in, a hole had to be drilled
into the botttom of the strut to have a bolt/screw inserted that screwed
into the Koni cartridge.  This was done at a BW shop that is vary familiar
with the process.  I know several other Roadster owners that have done this
and once you see what has to be done, it's not that big of a job.  30
minutes max on a grinder.
