Default STi vs WRX suspension geometry

I always thought the STi suspension geometry was the same as the standard WRX, but I started thinking about it (never good) and could not find anything to afirm this.

Can someone quickly run throught the differences?

Differences that I know of:
Springs
Stuts
Links
Bushings
rear sway bar

anything else?

Depending what country's STI you're talking about, the STI may or may not have the same suspension geometry as the WRX. For instance, pre-2004MY Japan-spec STIs had the same geometry. But all Spec C, 2004 to 2006MY US-spec STI and 2004+MY J-spec STIs have different suspension geometry due to different control arms.

I was just comparing USDM STI to USDM WRX.

I'm adding RCE springs and struts to my bugeye and was curious if my setup would be at a disadvantage compared to STIs with the same setup.

STI's have aluminum front control arms. The pin on the rear that goes into the rear bushing is bolted on, and can be fliped around to give more caster without the need for an ALK. More caster yet WITH an ALK.
