how far until the camber will need adjusting?

 

Just get the Eibachs without cutting extra, and you'll be fine.. No camber adjustment necessary..

There were so many posts about lowering... Please do some researching before Nismo gets on ya!!

 

Camber might be fine, but the stock struts/shocks might not be able to handle too low of a drop after some time. I believe the general rule is anything lower than a 2" drop will eventually speed up the wear and tear on the dampers.
