'04 STi struts with 02 -03 WRX springs and 225/50-16 street tires:
You can fist the rear wheel gap.
You can use stock GC rear spring perches and tops with 02 - 03 WRX style springs. If you have 02 -03 style rear struts, you need the TiC spacer to run the GC rear tops.
I don't run a rear sway, so no issues with making one fit...
Alignment came out to like -0.4 in the front with just the stock camber bolts. -0.8 in the rear with aftermarket bolts in the top holes.
