I have a set of ISC street sport coilovers that where on my wife's 05 LGT.
These have some where over 80k on them.
They where becoming very bouncy, getting the spring noise when turning the wheel and staring to leak oil on at lest one of the fronts. Also last time I tried I was not able free up the locking rings, but I really didn't try.
I believe all 4 shock inserts need to be replaced as well as both front thrust bearings and most likely some of the rubber dust shields.
I have a set of brand new unused rear stock inserts. They are shorter then the ones that are currently in the rears, at some point ISC went to the shorter rear shocks in the kits so people could lower the rears on the Legacys and impreza more. These new inserts go for $75 each from ISC.
I am asking $200 or BO + shipping for them.
I would prefer to sell the coilovers with the new rear shock inserts, but I mite sell them separately for the right price.
If anyone wants to make me an offer send it to me in pm.
