Need help on wheels sizes

[sprinter]

I am buying a set of Iforged for the vette, and want them primarily for the street and for looks. I will however be doing some Autocross... I have decided on 18x10" on the front and need help for the rear size. please give your opinion (3 options)

Rear: 18x10.5" (2.5" chrome lip looks the best but reduces width... this is my preference but I want to run at least 305s on the rear)

Rear: 18x11" (3" lip makes my vette look like a ricer ...but bigger width)

Rear: 19x11" (19" wheel is nice but limited choice of tires...now cant run Nitto 555R2)

I need help fast as I want to placce the order today. Thanks

For the street and show go with the 19" IMO. Either with the 18" or 19" is going to look great
