i'm not sure if they are exactly out yet but if they are, is anyone running them? how are they? i had ground controls on my integra and the ride was pretty clean so hopefully it's just as good on the tC :pray:

you mean the ground control coilovers from the CELICA?

i believe a few people are riding on it

oh thanks but on a website i found when i was surfing around last week they had ground controls of the tC for like 490. now that i think of it since it's that much i should just spend the rest and get the tein ss

Slip on coil-overs are POOP!!!! They ride like crap and are really bouncy. They are the ricers coil over kit. There is no sense in buying a new car and making it ride like ___ just to have it low. If you want adjustables spend the money and get the TEIN Basic Damper Kit.

i 2nd that

good putting it SUPAWHITETC

Um I don't know about that......when I was on honda-tech, a LOT of people had the Ground Control/Koni combo...including a lot of auto crossers. Ground Controls (well at least the springs) are made by Eibach.

Maybe you are thinking of all those generic cheap-o sleeve type coilovers out there.

oh boy.. haha.

i hear you niks. coming from an ex-honda-tech-er and a former ground-control user, i'd have to say they rock. combined with koni's they're better than anything tein has for street use. not too mention they're cheaper. ground-control offers customized spring rates and quality springs by eibach. if koni had struts out for our cars, or even a release date, i'd prolly hold off on the basics and wait for those. but they don't, and i'm not gonna run this car like i did my integ, so i'll prolly go with the tein hype.

do not generalize ground-controls with those other crap sleeve kits they sell on ebay.

Ok, I know that I'm gonna catch heat for this but is there any difference between normal coilovers and Ground control coilovers? Are they one in the same? Please, educate me in the school of Coilovers.

FYI: We sell a specific Ground Control Kit for the scion tC on Stock struts. I am sure you will see aftermarket struts in about 6 months and GC kits made for them.

mista3..

ground-controls are sleeve coilovers. it's a spring and a sleeve that goes around a seperate stock/aftermarket strut. the sleeve has a locking perch to spin up and down to adjust height.

teins, among others, are full coilovers. meaning there is no sleeve. the threading for the perch is on the strut itself.

oh boy.. haha.

Yeah I totally agree. I got the Tein basic damper kit for my tC. (Although I haven't installed them yet). But yes, it totally sucks that there aren't any aftermarket shocks out besides the TRD.

I just ordered Ground Control suspension from their website. I was wondering if you guys know a shop in San Francisco where I can install them. Thanks.

Finally, the first informative GC thread. Jesus, it was hard finding this thread.

Does anyone know how the custom spring rate goes? Can you just ask for a spec? Does it cost more? Can you use different springs with the sleeves?

Man you dug up some long dead threads.

According to Eibach's website, they have specific versions for "stock, Sachs, or Boge shocks." They also seem to have two version of the ground control kits for different cars (street vs. autocross).

You should give them a call if you've got specific questions. I wouldn't be surprised if they could work with you on what you're looking for.

Good idea, I e-mailed them last night and the guy, Mark, got back to me within a few hours. This might be for me.

h&r coils ftw!

Good to hear that they responded to your question so quickly. I hate it when places say they'll get back to you and you end up having to call them again.

Yeah. Custom spring rates. What's not to like about this deal. I've already got TRD struts/shocks, so I think I'm going to do it. Anyone wanna buy some TRD springs (white)? :)

Alas- If your planning on purchasing the ground controls to pair up with the TRD shocks, but would still like a confortable ride.. I would suggest requesting custom spring rates probably similar to the spring rates of the TRD lowering spring.... if you go this route, you'll still have a confortable ride but have the option of adjusting the height of your car.

Now if you want something that'll handle better than the TRD combination, you'll probably want to go a little stiffer on the spring rates.

BTW, I've owned two sets of ground control for the scion tc and both sets have come 440 FRONT/340 REAR... which I don't quite understand why Ground Control would choose these spring rates on a FWD. Luckily I am able to switch the springs around and try different combinations or i can always sell my current eibach springs and purchase some custom springs. This is one benefit to having Ground controls!

At least with ground controls, you can pair it up with any shock you want, ex: KONIs... a lot better than the cheap CHINA made shocks that come with a lot of the coilovers.

I'd like a little better handling. I can take a little bit harsher(word?) of a ride.

How come you have owned two sets of GC's? Just to switch out the springs? How else is the quality of the set? Do they make noise? Are they really "bouncy"? I would only imagine them being bouncy with retarded rates.

I want to eventually get some koni yellows :) That would be nice.

Please, more review and details, sir!

I have owned two set because I sold my first set thinking that I was just going to keep it stock and sell my car after a little while. But I decided that I want to keep my tC, so since I plan on keeping my car a lot longer than originally planned, I wanted to go back! That's how I'm on my second set.

My personal opinion, I think they are very well designed spring adjustment kit. The ride is stiff, not bouncy at all with stiff springs. I would imagine that even with lower spring rates it would still be pretty solid, because the springs that GCs come with are LINEAR springs which stays the same spring rate regardless of compression, not progressive springs (most lowering springs are progressive) which basically doesn't hit the spring rate spec that its rated until its compressed so far. I was actually thinking that if you choose spring rates close to what TRDs rates and pair them with ur TRD shocks, it would be pretty solid considering you'll be riding on linear springs not progressive.

If you plan to go any stiffer than what TRD has set their shocks for , I would say you have to go with KONIs in order to adjust them to match the spring rate (this is why I suggest choosing the same spring rate as the TRD springs). Now if the TRD shocks are made by Bilstein... then you may be able to get away with it.

Well I could always get stiffer rates just so they would kill my TRDs a little faster then I'd have an excuse to purchase new yellows :) am I right? How easy are the adjustments?

The Konis are very easy to adjust, except the rears have to be completely removed and compressed all the way down in order to adjust the rebouhnd. The fronts are easy and can be adjusted from the top without having to be removed.

I really don't know how well the TRDs would do in terms of comfort with the GCs. I think it would be alright even with the 440 front/340 rear... or you could just switch the springs around to 340 front/440 rear.

However if you want to adjust the rebound for more comfort, just sell the TRDs and use that money to invest in some KONIs. I am very satisfied with the comfort that only the Konis will be able to provide with the GCs - with generally any spring rate setup probably up to 500 lb/in springs before they would need to be re-valved for an even higher spring rate. Plus they are lifetime warranty!

Another reason to sell your TRDs is I don't know whether the GC adjustable sleeve can even go over the top of the front shock/strut. I know with the stock shock, you have to pop off a gold metal cap on top of the shock/strut so you can place the GC adjustable sleeve all the way down. If you purchase the KONIs, you will have to cut your stock front strut housing and place the GC adjustable sleeve on before you slide the Koni insert into the stock strut housing otherwise the GC sleeve won't fit over the slight ridge at the top of the shock/strut housing.

All in all, great setup... a lot of work to have this setup with all the cutting and drilling of the front strut housing, but in the end, it's well worth it. :love: :bow:

how do you'll think tokico blues and tein basics can fair with a ground kit. I been doing research just want opinions
