Best to keep same tyre/wheel widths front and rear from what I've read.
18x10 +18's would be ideal for a bit of track action, but Abu doesn't want that. Going by his previous ride's wheels, he wants tyre on guard action.
Bit hard to tell, but going by those pictures, you could probably fit some 10.5 0 offsets.
Just think about what we thought about your last set of wheel's specs. In theory, they were WAY too extreme, but in reality, PERFECT! Don't be scared to get something that seems too aggressive.
