I have a set of Forged light weight Signature SV104 in Black Chrome that I want to use with special spacers to get the correct lug spacing. These wheels were for my Porsche with off sets of 47mm f and 35mm r. I intend to buy special wheels spacers that fit both the Tribeca lug spacing and the Porsche spacing as well as pushing the wheels out additionally about 10mm from the offsets.
I am concerned that the overall running diameter of the tires will be slightly different from front to rear causing the Plantary torque converter LSD to overheat and fail. I could have my tire shop actually do a roll test of both the front tire on 9 inch wheel and rear tire installed on 10 inch wheels to see if they are actually different. If so, then I will put my slicks back on them for track use later this summer.
Which wheel would look best on my white 07 B9

Let me know your thoughts.

The rims in the top pic. This is only my opinion though. I would just do what works and what you like. I have no idea what will work on this vehicle.

Those rims will fit with a spacer/adapter maybe 10mm wide. The downside is the rims are 9 in wide f and 10 in wide rear. If that width difference will effect the rolling distance of the tires front to rear, then I could not use this set as it would case the torque converter to go nuts after a while as the fronts would be turning at one speed and the rear would be turning at another. I can have my tire shop do a rolling test to make sure they roll the same distance. Then I will have a forged light weight chrome powder coated wheel set. No need to look for WRX/STI wheels.

let me explain to you how power flow is happening in transmission (in tribeca):
1) engine goes round and round and round(creating torque).
2) engine is connected to flexplate, which is connected to torque converter.
3) after torque converter - magic is happening torque converter looks like this - Torque Converter & Converter Case - 2008 Subaru Tribeca (there are minor differences between pre/facelift, but... omit them for now).
4) after magic has happened - there is CENTRAL differential which "divides" this rotating motion(flow) into two rotating motions - for FRONT and for REAR. I think you meant "central differential",
central diff looks like this - Automatic Transmission Transfer & Extension - 2008 Subaru Tribeca
5) so, while in theory, 3 differential setups allow for differences in circumferences(let's not go into deeper details why your wish is just "looking for trouble") - in harsh reality - it will pretty soon be toasted.

p.s. this caught my attention recently:

Thanks, not interested in the VW system. 06b9beca can put it in his ridiculously slow 50+ MPG wagon. Just not my thing. I think for an uncomplicated LSD the Wavetrac is fantastic.
