Potenza S-04 vs Pilot Super Sport on CS7's (decision factors)?

I have narrowed my choice to:
- Bridgestone Potenza S-04 Pole Position
- Michelin Pilot Super Sport
* Both tires are well respected/highly rated
* Comfort is acceptable
* Wet and dry rating are high
* Both are quiet tires, compared to the competition (through the life of the tire)
* Both have stiffer sidewalls
* The PSS's are a lighter tire (better unsprung weight)

Setup and driving:
- KW SC C/O's with a 5/8 to 1" drop (on order/not installed)
- Alufelgen CS7
- FR 225/40/18 RR 255/35/18
- Daily driver + spirited driving, no track use
- Currently on Dunlop SP Sport 01 DSST RFT's
- Tires will be used all year (SOCAL weather)

My key decision factors are:
1. Rubbing and fitment
- I have Alufelgen CS7's (18") and read about rubbing issues on the PSS's
- The S-04 tread width seem to be have slightly narrower tread width (.3 narrower on the rear tire)
* That might be a good thing (rounder sidewall)
* I am willing to do a fender roll, if necessary

2. Cornering response
Since I am coming off of RFT's and who knows if I will ever get the M3 control arm kit, I removed other tire choices due to the softer sidewalls and poor cornering response
- The S-04's seem to get equal or slightly better overall rating cornering response compared to PSS's

3. Tread wear
- Hopefully get decent miles out of the tire
- The PSS's have a better UTQG rating (300 vs 280), but who know if this really means anything...
- The S-04 claims superior tread wear toward negative camber

Finally, My questions are:
- Has anyone ran both the S-04's and PSS's? Any comments/comparisons?
- Anyone with Alufelgen CS7's running S-04's? Any fitment issues?
- Did you get the expected life out of the S-04's/PSS's?
- Did the extra weight of the S-04's seem noticable?
- Any uneven wear due to negative camber and lowering?
- Just go with the PSS's and know that you will be able to fix the rubbing issues!

Any help would be amazing... Thank you!
