I have Konis supplied by Quella.
I took the following # off mine - 30 1301 1000.
'30' referred to the series 30 shocks, (gas-filled, sealed and not rebuildable)
1301 was the style (oval track with heim
joints for the upper/lower mounts
1000 was production date code (10th week of
the year 2000).
These are rebound adjustable shocks that must be removed from the car to be adjusted according to the factory sequence.
Springs are also from Quella and are -
GT5 SPRING RATES ARE:
FRONT 450 POUNDS
REAR 550 POUNDS
Hope this helps at least a little bit.
