Where is a good place to go for good z parts? Is there some mystery catalog I don't know about, or does everyone go to a "performance shop"?
I'm new to this and need help.

 

junkyards and zcar.com parts forum are your best bet. if you want new parts, order a catalog from motorsport auto (zcarparts.com) or victoria british. just expect to pay up the wazoo for them. if you want performance parts like bushings, you can order them directly from manufacturers like energy suspension

 

The popular "Mystery Catalog" is probaby Motorsport Auto's catalog as mentioned above. Go to their web site and request a catalog.
