I am about to put about $10k into my car, engine, suspension and wheels/tires. (2014 435ix Black Sapphire Metallic)

JB4/intercooler/catless DPs/intake
H&R Sport springs
Gunmetal VMR721 - 245/40/19 and 275/35/19 - Michelin PSS 4S
Possibly Remus axle back (this puts me over 10k)

Objective is to get this to the driving machine it is supposed to be, but also look a lot nicer. I am not sure I will track this car (I don't think the rest of the car would keep up and it would be frustrating). I want really nice feel on on ramps, LOTS more grip, a rewarding cornering, with a neutral balance with the understeer gone.

I absolutely hate how high this 435ix sits, I might as well have bought an SUV.
I have been reading lots of the threads, and I have found the look of the car I want:

VMR721 is a beautiful looking rim, elegant and has the concavity I want. I certainly like the look of stagger, with the big fat rear tires and excellent fit of the VMR brand.

I know a square setup is probably what I should do.. but I love these rims.
A 255 probably won't fit on these rims on the front, then I have the 1% issue again on XDrive, so this limits me to options.

Questions:
1) How much understeer is this going to have compared to stock?
2) Will I meet my objective listed above with a staggered setup on the handling?
3) Will the H&R springs, and a 245 front be good enough for a lot more grip and faster cornering ?
4) Should I put on camber plates for better cornering?

What do you think?

(PS: the black pictures are of a VMR701 which is similar to the V721 but only black / gunmetal pictures I could find). It is really sweet looking.
