Strut / Spring FAQ

This FAQ has been written by fwa2500. The original post can be found HERE

I am tired of the same questions being asked over and over again, so here is a FAQ that I have put together with the help of Reuben.

Will STi struts and springs work on my car?
Yes, but only '04 STi struts will be a direct fit because in '05 the hubs were changed from 5x100 (which is what your car is) to 5x114.5. '05-07 STi springs will work too, but also require the '04-07 top-hats. Additionally, any '02-07 WRX set-up will work since the WRX never changed away from the 5x100 hub.
I found some '05 STi struts and springs, can I use those?
The springs, yes, but not the struts for the reason mentioned above.
How much lower will STi struts and springs make my car?
Approximately 1 inch.
What about WRX struts and springs?
As stated above, yes they will fit. Any '02-07 WRX strut, spring and top-hat combo will work on our cars. These will only lower half an inch at most with the stock WRX springs.
Can I use just STi springs?
Yes, but you will need the 04-07 rear top-hats if you are using 04-07 springs. If you are using JDM springs meant for a bugeye (GDA) you should be able to use your stock top-hats.
Isn't STi stuff really expensive?
It can be, but for a complete set of '04 STi suspension you are looking at about $300-400, which is a pretty good deal when compared to our stock set-ups.
Would 3rd or 4th gen stuff work?
Unfortunately, no. Both have a completely different rear suspension set-up.

I want my car lower, what is the easiest way to do it?
Get a good set of aftermarket struts or springs, or even both. DO NOT cut your stock springs, not only does this decrease your handling performance but it can be very dangerous.
I want my car slammed and heard S-Techs are the way to go.
No. Just no. You might as well cut your stock springs, just get a good set of performance springs and enjoy. You might not be quite as low, but you and your car will thank me. Please see THIS THREAD on NASIOC for more info.
I've heard wagon and sedan rear struts are different, won't you get 'ass sag' with sedan struts in a wagon?
Generally it's chassis related. In most cases, second gen. Impreza (bugeye-hawkeye) suspension works just fine in our second gen. Legacy wagons and sedans. The exceptions being the 05-07 STi struts which don't work due to the different hub. GC/GF (first gen. Impreza) stuff also works in Gen 2 Legacy's, but GC/GF Impreza rear shocks and springs are shorter, and so you get the 'ass sag', regardless if it's from a wagon or a sedan.
Is it hard to swap struts over?
If you've worked on cars before and generally know you way around, no, it's an easy job. I recommend having a friend help out when installing the struts, it makes things so much easier. Keep in mind that you must get an alignment done once finished.
Ok, I installed some WRX suspension and now my wagon has a saggy butt. How do I correct this?
Spacers. Putting spacers in between the top hats and the top strut mounts on the car will help correct the sag.
That is all good and all, but let's say I want to **gasp** raise my car.
In that case, your best bet is swapping on BD/BG Outback struts and springs or second generation Forester struts and springs.
All that performance stuff is nice, but what about just replacing worn out OEM struts with stock-spec struts?
For that I would recommend KYB GR-2 struts, they are nicely priced and are excellent quality all around. Another option would be Monroe, they are also good stock replacements.
While I have the car in the air, what else can I do to make my car handle better?
One simple thing you can do is install camber bolts. These will give you more available camber (can produce both positive or negative camber) to fine-tune your alignment.
What about swaybars and endlinks?
Good question, please check out Zeus Marine's repost of Jamal's excellent swaybar FAQ HERE.
What are you running on your car?
I currently have '04 STi struts with '05 STi springs, a 22mm adjustable Whiteline rear sway bar, Tribeca 25mm front sway bar, Kartboy solid front and rear endlinks, Ingalls camber bolts on all four corners and a slightly aggressive alignment (-2.3 degrees front camber with zero toe and -1.4 degrees rear camber also with zero toe).
More will be added as is needed. I hope this helps some
