Default Ground Control Coil Over Kit

Anyone hear anything about these? I need some real life info on these. I can't believe it's a coilover kit under $500. They use Eibach springs too. Anything any of you know about these will help. Thanks.

These are not a true coilover kit. They are threaded collars with matching spring seats/eibach springs (they have various heights and rates for you to chose from)/and finally matching spring hats. You will still need to buy a set of struts. AGXs give you the ability to adjust valving for stiffer of softer dampening.

Ground Control Kit = $400 + shipping
KYB AGX Struts = $400 + shipping

I have been using mine for under a year and have had favorable results.

Just remember anytime you stiffen your springs the softness of your daily ride will be degraded. If you are willing to sacrifice that this kit is you most cost effective choice.

Thanks Brad on the 411. Still for $800 +shipping, you can't beat that. I will look more into these, but I might be purchasing these.

Don't buy Ground Control unless you get their ADVANCED DESIGN shocks. I had them on my Civic and they made popping noises every time I turned my wheels and the cause quite a bouncy ride unless they are well-damped. I'd recommend just saving some money and getting some real coil-overs.

Just my opinion.

Ground Controls are great unless you spec the wrong spring rate/length for what you want to do with your car. Some people are into the show scene, so they should pick a short spring with lower spring rates. Some people are into autoxing, so they should pick a longer spring with very high rates (and get shocks to match!). Some people are into rallyxing, so they get springs that are long enough to raise the car from its stock height.

But if you end up picking a super stiff, super low spring that fits over stock struts, you end up with a horrible ride and lousy handling. This is what happens if you buy them from say, NOPI. But if you consult the guys at GC beforehand and buy directly from them, you should end up with a wonderful package. I know I loved their setup for my 2.5RS. Just make sure you ziptie the tophats onto the springs to get rid of clanking over bumps and possible instability at high speed.

sms1, it sounds like there was something wrong with your setup! & if it was too bouncy, you got too high spring rates and/or shocks that couldn't deal with them.

sorry, but yes they are...

perhaps not in the way "coilover" is commonly referred to on this forum, but in fact, that common referrence is wrong.

"coilover" simply refers to an adjustable ride heigth spring/perch setup. in practice that translates, to either a threaded sleeve that slips over and attaches to a strut housing, OR a strut/shock with threads integral to the shock body... both are "coilovers".

sorry, but i've had two sets of GC's and i've never paid more than $300/set...

exactly, but they will work with other shocks . . . i ran them on my civic si with bilsteins, and another set on my integra type R with koni yellows, and they were wonderful - provided you get spring rates that the shocks can handle. the adjustability of the konis made it even better to 'tune', if you will. both the bilsteins and konis can handle up to about 800lb/in rates. the AGXs i've heard are considerably weaker, and can only handle about 300lb/in, so i would not recommend using them with GC's unless you're using spring rates below 300lb/in.

also, regarding the rattling issues . . . i never zip-tied the tophats to the springs, and never had any rattling issues. i was running the 8" springs, so maybe that's why...

thumbs up to GC! don't believe all the negativity they get - after all, a LOT of BMW racecars use them.

I have nothing but great things to say about the Gound Control crew and their products. Ground Control is one of our sponsors for One Lap of America this year. We're campaigning a MY00 Impreza 2.2 RS-T.

My advice? Call Ground Control and talk to them. All of the guys there are very well versed in Subaru's; from RS's to WRX's. They even own a WRX that runs one of their own setups. Tell them what you're going to be using the car for, whether it be a daily driver, auto-x car, or even to Hillclimb.

I've run their coilover setup with multiple sets of springs for the various events in Hillclimbs, Track days, auto-x's, Rally-x's, and I daily drive my car. All this translates into a suspension that you can adjust for just about any situation with optimal results.

Ground Control has been pushing the market and supporting Subaru's for awhile. Not only our car, but Gary Sheehan's as well. My opinion?? Give them a call.

a second to what fitz has written...

I run a ground control setup on my ITA scirocco and am quite happy with it as well as the service from GC... call them with your questions.

by the way, one of the knocks seen here on the GC setup is getting the correct rates... in fact, that's one of their strengths... they use standard size springs (Eibachs) that are relatively inexpensive, so it's easy (and cheap) to tune your suspension with a collection of different springs/rates. (again see Fitz comments)
