over the winter i swapped out the FRPP springs for some sportlines i had. The isolators on the frpp's were shot, and the sportlines didn't have any from the car is came off. I didn't think it would make that much of a difference, and the car is really down there now. Now driving it around when i hit a bump it bangs like a bitc*. Do u guys think its because there are no isolators on the front springs? or something else, i changed the shocks, springs, tie rods, and stab. links. I took it for an alignment and they said it looks like everything is fine, i didn't mention the lack of the iso's. So im leaning towards the lack of isolators.
