With guard rolling or with out?
around +42 seems to be the rule with out.

imo, nothing lower than +40.
thats what i have on now, and its pretty much straight down from the fenders.

yeh guards will be rolled... its running somewhere in the region of -5/-5.5 camber at the moment, its pretty much layed out as low as the rear will go... so im aiming for lowest offset possible then dial out camber from there

[akina]

wow, i'll get that camber fixed up asap! or u'll need new tyres very soon.
max i'll go would be -2 camber. with that and rolled guards, +40 offset is fine.

i have 18" as well with +40 offset, running -1.5 camber at rear. lowered to about half a finger gap.

I think best is to use the offset calculator online. http://www.1010tires.com/WheelOffsetCalculator.asp
Well, after your at the height your after, say get the camber corrected like AKINA said, maybe -2, measure how much more you want it to stick out or in,. then play with the tyre sizes. If your after crazy camber, rolling guards, you will be able to fit very crazy offset like +35 in front..but that is not recommended coz your tyres will wear like crazy. Have a play with it though.
