What are your over all goals? I assume just aggressive street since you have a soft 250 lb spring up front. As well, a 12" spring will not be kind to larger front wheels. You will want to look into a 10" spring for sure. How much clearance do you have to the bottom of the front coil seat to the wheel? Do the math with the larger wheels and tires.
For Autocross, and road racing a square stance is more ideal and you have the ability to rotate tires.
Staggered stances are not ideal for front engine cars as you will have wasted grip with a larger rear tire and smaller up front. Car will tend to push more easily.
If this is purely for looks, honestly a fat front and matching rear tire with larger fenders looks sick on these cars. But staggered wheels have their place for sure.
