I'm an advocate of a matched strut/spring combo. For the cost of a set of junk coilovers, you can get a strut/spring combo that will easily outperform the cheap coilovers.

My recommendations for Alaska? Feal revalved 04 STI struts with RCE Yellows if you want a progressive rate or Swift Spec-R if you want a straight rate spring.

You'll notice that the RCEs include bump stops, and that Swift instructs you to modify the stockers, no one else addresses this crucial area. The WRX/STI already rides on the bump stop stock (even though it has more than enough strut travel), when you lower it, you're even further into it. A fully compressed bump stop has a spring rate of INFINITY, which certainly doesn't make for the best ride.

Mild drop with both, that doesn't negatively affect the roll center and LCA position, and the revalves are an excellent addition to the already strong inverted STI strut setup.
