Boosted

when i first got them I had them installed...they were on the car for about 3 months and I started to have really bad handling...with rear drifting around alot...i was unable to set ride height correctly...drivers side rear was consistently sagging about 1 inch...anyways it appeared as though I had a faulty rear spring which in turned caused premature rear shock failure..I sent it back to Bilstein and they sent me a new spring and shock.. They tested the spring and agreed that it had collapsed..anyways I installed the new parts...they lasted about as long as the old ones mileage and time wise..the new spring has completely collapsed with all coils touching, with the top half coil compressed into the centre...anybody have these kind of problems with this system??

but i think thats normal, as long as the top and bottom coils are spaced out.
