If I go with the 20mm spacer can I avoid this, keeping in mind that I will also be dropping it with the Eibach's. Thanks for the help, gotta love the forum!

I have a 10mm rear spacer and I'm going to put those spacers on the front and put 20mm on the rear and I already think my rear tires/wheels look like the tops are "sunk in" It's a little hard to describe but it looks like the top needs to be pushed out. Is that camber? Is there much adjustment there? How are other 370z's with spacers keeping there wheels/tires looking perfectly vertical. Please let me know if I am not making any sense? I appreciate all your help!
