Wheels and Tires for my 35is

Hi all,

I hope I put this in the right section but...

I'm considering my first upgrade for the zed as being tires and maybe wheels.
I'm currently rolling with the Star 295 18" wheels and am considering something lighter and larger after reading about the stock wheels.

So heres my options followed by some data.

Option 1: ~$1100
Replace the rubber with PSS. The RFT's make me sad when I drive my PSS equipped 2012 WRX.
I don't really mind the stock wheels but they have some wear on them from the previous owner and are heavier then the TSW's.

Option 2: ~$2700
I would like to buy some 19" TSW Nurbergring wheels and wrap them in PSS rubber.
Expensive but I like the weight savings of ~7lbs a wheel.
Of course I also like the way they would look on my blue zed .

Questions:
So if I do option 2 what TSW wheels do I select to keep the car from rubbing or driving poorly?

Front seems like a no brainer since this can be a direct stock replacement
FRONT: 19x8 225/35-19 OFFSET 35

Rear has me scratching my head though after looking at these places:

(TSW fittings guide) REAR: 19x9.5 255/30-19 OFFSET 41
or this
(Discount tires) REAR: 19x9 255/30-19 OFFSET 20

TSW is half an inch wider then stock and discount tires has a 21mm offset difference.

The primary goal is to get the car glued to the road more without ruining its DD usage.
But I really like the idea of losing ~28lbs of unsprung weight....

Thoughts?
