I like a 20 mm stagger front to rear (like stock). 9.5" front and 10.5" rear are 1 inch different or 25 mm. Allows you to install 275/30 and 295/30 tires with similar look / fitment on the front and rear (wheel width 25 mm different and tire size 20 mm different). You could also go with 255/35 and 275/35. A 9" front limits you to a 245/35 or 255/35 in the front (265 or 275 on a 9" wheel is too wide IMO). A 10.5 et27 allows you to run 295/30 rear tires without rubbing. 10.5 et 22 with 295's will rub. Your proposed 10.5 et 30 should work but you will like the more aggressive look with et27. A 9.5 et 22 with 275/30's in the front on a lowered car will require negative camber but it will look and drive fantastically. Any higher offset (more inward) will rub on KW clubsport coilovers on the inside. You may not have coilovers now but it will be good to have the option in the future without requiring spacers.
I hope this helps!
