245/45/17 up front what offset is needed?
For SCCA Solo II I would like to run 245/45ZR17 on all four corners what offset will be needed? so that I do not rub?
What is the stock offset, 45mm?
The wheels have to be 17x7"
How far out will 245 stick?

You're in for a surprise if you want to put tires that wide & that tall on an IS... a 245/45-17 is just (barely) more than 1" taller than the stock 215/45-17, and is way too wide for the narrow 17x7 +50 wheels (most tire manufacturers specify a minimum wheel width of 7.5" for this tire, an 8.0" to 8.5" is closer to optimal).
I don't think there is any possiblility of these not rubbing, especially in the front, regardless of offset. Not to mention how different your gear ratios will be with such a tall tire...
