So I was looking at rockauto.com and found these.... I took a screen shot of the kit and a link of a full sized pic...

Looks like the rear toe bolt for adjustment is also included so it complete the rear camber kit compared to the other kits that sell the bolts for $40.

Check it out at rock auto, then look for the 350z, year, and compression arm section, and that is where the rear camber kits are.
