I've done the research, and while it doesn't look too difficult, it's just that I'm not really into the hassle right now.
I ordered my new rear tires and they shipped from TR today - Hankook Ventus R-S3 305/30/19s. Also ordered my SPC rear camber kit with toe bolts from forum sponsor B2 Auto Designs. Also shipping today.
Hope to have them all by the end of the week and have my Z back on the road for the weekend!
