After lowering my VP on super lows I found out that I needed shorter shocks to keep the springs captive. After searching the forum no one had posted any part numbers or where to find them, so here is how to find the right springs and shock part numbers for almost any Commodore.

Look up your model in these catalogs.

King Springs:
Catalogue

Monroe - Shock absorbers:
MONROE 2009 - 2010 CATALOGUE

KYB Shock absorbers:
KYB Shock Absorbers - Australia

These are the ones I used, now I am off to buy some new shocks on Monday.

PS. add some more if you know more brands
