Thanks to all for helping guide me with my wheel/tire/suspension upgrades!
Work Cr2p 19x9.5 +15 (f); 19x11 +13 (r)
Michelin Pilot Sport 4s 255/35/19 (f); 305/30/19 (r)
KW v3 set to factory dampening setting
SPC front and rear camber kit
Two finger gap; will drop another 1/4-1/2" once springs settle
Alignment is more or less within spec; could use minor castor adjustment
No fender mod, no rubbing (even at high speed over moderate bump)
Front pokes a tad more than back but still more or less flush
Front tire has a very minimal stretch, while back is fully square
Would not go any lower; this setup has the ideal look/functionality balance
