Thanks for the inspiration to clean the Suspension .
Under some dirt and grease was the answer I was looking for.
The shocks are stamped Koni Holland 30 1301
and I guess this setup was sold by Pantera Performance.
I did print the page on Suspension from Pantera Place..such a great Site
It does look a bit more tidy..the calipers are next and I wish there was an easy way to Paint them
I would hate to have to disassemble the the Suspension in order to get the Spring Rates.
What Brand are the 450s and 550s?
