How to achieve this stance please?

So I dont even own it yet and I'm already planning changes :D
The car has factory 15" steels, so I'm planning probably 225/60/15 as a step one, unless you tell me I can go bigger at the back?
I´m guessing the factory wheels are 15/7"?
There seems to be a fair amount of space between the wheel and fender at the moment.
Step two are new leaf springs with at least 2" lift as the back seems really low.
Superstock do seem a bit of a overkill for 318 with standart 7 1/4 rear, so is there tested middle ground for the springs lift?
Then lifting the front about an inch to give it some rake.
The red Scamp on the pictures is what I´m looking for in terms of stance.
Many thanks!!
