I finally resolved my noise problem and the Ohlins are
now handling like a dream. The racket was caused by the spring shifting
under load rubbing and popping against the camber plate perch.
The shop who did the install didn't use the rubber spring isolator from
stock struts and this is most definitely necessary!
Had my first track wknd with the Ohlins and was stoked on the performance,
much tighter and controlled than stock zcp. I think they really nailed it for
road and track dual duty setup.
