Ok, so I've spent countless hours scouring "teh intarweb" for possible suspension setups for my '05 RS. I've browsed all of the reputable online retailers and searched SECCS, RS25, and NASIOC. Here's what I've come up with in the way of options, and I have a few final questions for you experienced folk.
To start, here are my major stipulations: First off, I'm more concerned about ride height adjustability than damping adjustmet. Both would be nice, but the former is my "must have" so I can crank my height back up to stock-level in the winter snow. I also want to maintain a decent ride comfort, but I expect to encounter a bit of harshness. The furthest I really expect to drive is Derby field for auto-x or San Fran perhaps twice a year, so long trips aren't really an issue. Finally, I'm obviously doing this for reduced body roll and better cornering performance, with an added bonus being the visual improvement a height drop would provide. In all, my key focus is a balance between comfort, performance, and adjustability, without spending way too much. Option 1: Ground Control coil-over sleeve kit (with Eibach springs) on KYB GR2 Struts. About $700. This will give me ride-height adjustment, no damping adjustment. Pretty much my basic option. Option 2: Ground Control coil-over sleeve kit on KYB AGX struts. About $900. Same ride-height adjustment with the Ground Controls, but the shocks give me a damping adjustment option for compression and rebound (combined). Option 3: JIC SF-1 Coil-overs. About $1500. These are entry-level coil-overs, with adjustable ride height, but no damping adjustment. They include camber-adjustable front top mounts. This is really something I'll only consider if someone can give me a damn good reason I should spend an extra $600 over Option 2 just to lose my damping adjustment. ![]() Option 4: TEIN Flex Type coil-overs. About $1600. Added on Scott's recommendation. Separate height and pre-load adjustment, and combined compression/rebound adjustment. Camber-adjustable top mounts. EDFC compatible in case I ever feel the need to be able to adjust my damping from the driver's seat. I need feedback from anyone willing to share it, before I go and drop a grand or more on this. I'd greatly appreciate any alternative options or suggestions, advice on possible compatibility conflicts that I may not be aware of, and opinions on what will give the best bang/buck ratio on a daily driver that will see semi-frequent autocross/track days. Feel free to warn me of any other parts, options, or costs I may need to consider for proper installation, as well. ![]()

Tein Flex. Period.
They're the best compromise between streetability and performance, they're fully adjustable, and the height is adjustable independent of the spring pre-load, so they'll be easy to raise up in the winter. They've got 16 step rebound adjustment, camber plates w/ pillow ball top mounts. Plus they're like $1400 IIRC, so they're cheaper than those JICs you're looking at. A lot of folks here on SECCS have the Tein Flex's.

I was looking at those as well, but I saw them listed at about $100 more than the JICs. For an extra $100, though, the added adjustability is definitely worth considering. I'll stick those in as #4.
Do you think in my case that full coil-overs be enough of an improved investment over a set of Ground Controls and KYB AGX to really make them worth the exta money? $900 is an easy decision. Spending almost twice that for options that I may or may not get the opportunity to take advantage of is not such a simple decision.

Tein is good stuff. Just remember every time you change ride height, you get to reallign the car.
Also, due to the terrible suspension geometry on the Impreza(Assuming it hasn't really gotten much better in 05) once you get below about 14" wheel center to fender, you run into excessive positive dynamic camber under cornering, and braking. This is bad! So bad that Competitive A Stock STI Autocross cars go to the absolute stiffest front sway bar available to minimize this affect despite what one would normally consider way overstiffening the front end. And that is at stock ride height! The net is lowering an Impreza can actually hurt cornering, so if done for cornering reasons, it needs to be done carfuly in moderation.

Can you define "moderation" for me? I'm not going to slam the car. . .
And re-alignment is no biggie. Essentially I want to be able to run the car about 1.5" below stock (or so - depends on how it rides) for most of the year, and then raise it back up to stock for ground clearance when I have my winter wheels/tire set put back on. That'll require me to have it aligned anyway, so I'd do it all at once.

Werd. Tein Flex, or the GC/AGX combo if you want to spend more time on your setup and less money.

Helix have released some new coilovers that look interesting:
http://www.i-club.com/forums/showthread.php?t=111200 2 versions, a race setup with 10/8 springs, $2300, and a street setup with 8/6 springs, $1000. Both come with camber plates up front. |

Holy crap. I just fired an email out to Gruppe-s to get some more info and ordering details. At that introductory price, they may be just what I need!

i dont know if they have those helix coil overs in quite yet...although im not positive...i think they just got in their test model for the shop...anyway i would definitly back the flex coil overs....not only are the easy to adjust in terms of both ride height and rebound...they can also be rebuilt fairly easily in the united states. i have had no problems with mine and i have been drving on them every day for the last 2+years(22000 miles)....

I think I gotta give them a shot. For a grand I'll be a guinea pig if the set has a chance of giving me the performance they're advertising.

I originally had my teins set to the recommended height which I though was way too low. I raised it about 3/4" from that and the car handled much better.

youll have to give me a test ride when you get those helix coil overs on. i only saw them when they were sitting on the shop floor. they looked pretty sweet and for 1000 bucks they are even sweeter.

I'm about to order those Helix DNA coilovers. Is there anything else I should pick up or know?

It is indeed an addiction, and any sane person would run away from this moneypit of a hobby screaming as fast as they could.

All hobbies are moneypits. Some are just more expensive than others. . .

Yeah, cars & racing just happen to be one of the most expensive there is short of aviation & spaceflight...
