Blitz Z3 wheels offset

I have a 2002 Q45 F50.  What would be the best size/offset to get the maximum lip.   I've noticed there is a hi disc and lo disc.   I know the disc matters on brake clearence but does it make much of a difference on lip size?

nothing they offer is going to get close to maximizing specs for your car with those wheels.

Disc specs can make a decent difference on lip size... at least 1/2" i think

so i'm guessing the biggest wheel and lowest offset should work fine...

pretty much with those choices.
