High camber is More positive. Low camber is more negitave....
Honestly, With a custom build /fenders i think you need to pick a size Sounds like 18x10/11.5 find something that is somewhat agressive, then mount it and figure out exactly how much of a spacer you need for your look that your going for. Then order a custom set of wheels to those specs. Or buy adaptors to go to 5x114.3 and then you have probibly tons of choices and cn pick up something from nissan for muscle car forum.
