I've got an 87 Formula. I just picked up a base model 87 bird parts car that the owner had done a bunch of work to, and then decided he wanted something else. One of the things he did was replaced the shocks and struts with standard replacement parts. What i'm wondering is there any difference in the valving between base shocks and struts and WS6 ones? I need to replace mine, but if the base model uses softer valving, I'll lose some handling. Thanks.
