You can save a bunch of money by piecing it together yourself and skipping the aluminum control arms. That will also make installation easier.

 

The aluminum control arms basically just reduce the unsprung weight of the suspension. Good on a race car, but not really worth the money on a road car.

You have a WRX right? 22mm will be fine,, adjustability isn't necessary. It's more important that you get a really good feel for your car before you make major mods. You should then try to tune the things you notice that you can imporve, rather than just copying what other people are doing.

 

That's correct. Unless you drive your car at or near the limit, you're not going to notice much difference in sway bars. You may notice less body roll and MAYBE a bit more spring rate in random bumpy stuff. The real place that swaybars make a difference is whether your car over or understeers at the limit of adhesion. If you don't drive your car at that level, forget about swaybars. In fact, unless you have a lot of money, why waste it on a suspension kit that you really won't notice all that much. I don't mean to jump to conclusions, so let us know what kind of a driver you are.

 

Gotta disagree about sway bars Tim. I got utterly schooled at my last (ok, first) autocross, but I definitely appreciate the difference that 20mm FHI bar made on my car. Of course, it didn't help my cause that I went with Kostamojen, Bemani, Egan, and others who don't suck.

 

Sounds like a good neutral setup. My significantly lighter RS is near neutral on stock struts/springs and an STi 20mm RSB. You should be with that one.
