If you are going to run any degree of negative camber other then OE, why bother with a camber kit?
My car sets at -0.5 with the kit, -1.5 without the kit.....if you aren't going to run OE camber why even have the headache of the camber kit?
The Ingalls kit should set the tire just slightly in a tad more in total, I'm not sure it would matter in the grand end though. I'm effectively back to -1.5 for the time being until I get my car aligned and I can't tell the difference from -0.5 visually at the moment....
