I have been doing a month of research about suspension and i want to either get Tein, H&R, or skunk2 suspension but every where i look on HondaTech, all i see is Ground Crontrol, Koni, Eibach, Ground Crontrol, Koni, Eibach,Ground Crontrol, Koni, Eibach, and on and on.

Why do everyone suggest Ground Crontrol, Koni, Eibach, over other brand? are Ground Crontrol, Koni, Eibach, REALLY that great? every thread i see about Tein, H&R, or skunk2, othere always say " go with Ground control with koni or eibach"

What is the big deal about Ground Control, Koni, and Eibach?

 

life time warranty

 

If you actually did read up then you would not have to ask this question. You, my friend, are looking for more people to tell you it's okay to go with any of those other setups.

I researched new suspension. When I noticed the overwhelming positive response of these setups (Progress included) from knowledgeable forum members and not pimple faced non-experienced teenagers, I chose one and was not disappointed.

 

best color combo out right now

 

I have been in an eg hatch with Tein and I now own a eg hatch with Progress Coilovers. Put it this way I am really impressed with the quality and workmanship of progress and I can do other things with the 1k I saved! Don't know about koni/gc, but I do know after doing the research I learned the koni/gc setup can handle everything you throw at it. You can be slammed, you can be whatever you want and have a little discomfort. I ride low not slammed and very very comfortable! Progress is awesome!

 

price aside, how would you compare your experience with the tein vs the progress?

 

I think he said they were awesome.

Because these products have all been tried, tested, proven, abused, and done so over and over and over again for YEARS and the results of that have always been positive. Not to mention that the price you pay for these brands is VERY reasonable for the performance you get out of them ALONG with a lifetime warranty. It's kind of a no brainer as to why so many people recommened them.

The Koni Yellow Sports test well on dyno's, work well with a high range of spring rates(stock ~90lbs/in spring all the way up to ~600lbs/in springs). They come with a lifetime warranty. They are fairly priced for what you get out of them. And you are able to rebuild them and fine tune them for a fair price. These shocks are also VERY popular with the budget racer for all of those reasons and if you go to any track day, you WILL find cars using them.

The Ground-Control coilovers are widely used on Civics/Integras, S2000's, RSX's, Miata's, BMW's, etc.. They produce high quality parts. The adjustment collar is easier to use because of the allen key rather than 2 locking collars. They use Eibach springs. Come with a lifetime warranty. And just like the Koni's, they are VERY popular with the budget racer and you WILL find cars using them at the track.

Same deal with Eibach. Their springs are consistant and fair priced for what you get out of them. Again, WIDELY used in all types of motorsports racing.

Are there products out there that are better than these? Sure there are. But are they in the same price range while being as versitle as these? No, not that I know of atleast..

BTW, Koni and Ground-Control user here. I've had the Koni's on my Civic that I autox VERY often and see tracks with for about 4 years now. Originally bought the sports and used 450/550 springs. I later sent them out to be rebuilt for 650/800 springs. Both the Koni shocks and the Ground-Control coilovers have treated me very well and I've had ZERO issues with them for the entire time I've owned them. I've also had Koni Sports on my old Neon ACR which I RallyX'ed. I abused those shocks more in a few events than most would see in a few years of use on a street car. They worked amazingly well off road and again, zero issues.

 

Quality of the materials used, not to mention Eibach springs they use

 

Great video.

 

thanks civexspeedy. this is exactly what i was looking for.

 

it all boils down to what you can afford..

 

And everyone can afford everything.

All you have to do is wait a few more months.

 

so how much would it cost to have a smooth ride? my car will NEVER be use for drag, Auto X, or any kinda of MAJOR racing. I Just want a smooth ride to cruise, travel and withstand pot holes while riding low. (not to low though. i know it wont work)

 

You should look @ progress as an option as well. How long are you planning to keep ur car?

 

Koni GC is a far over rated setup. The GC sleeves are good, but its simply a threaded aluminum sleeve. Anything from a reputable source ie, eibach will be fine. No need to religiously use GC. An issue with running these is that the threaded collar is usually not long enough to run a helper spring in order to keep the spring tight against the upper perch. Now when youre at partial to full droop, you run the risk of your spring not seating properly when it regains contact with the upper perch.

Koni Yellows are probably the most over rated shock out there. Forums have done a marvelous job at hyping the **** out of them for who knows what reasons. The bodies are too long for lowering most cars more than 1 inch. You immediately lose shock travel when lowering ride height, which wouldnt be an issue if the shocks had shorter bodies (starting at a lower height to begin with at full droop). Solution? extended top hats. Extended top hats on a double wishbone car with as much room as the Hondas have is a sorry excuse for bandaiding a poorly designed coilover.

Second Issue with Yellows is that they are not valved (off the shelf) nearly stiff enough for a lowered car with reduced shock travel. Like it or not in order to be low, you need to be relatively stiff to make up for the loss in travel. Yellows valving is not only soft, but spiratic - with no gaurantee the valving will be on the same setting between changes.

You can address some of these points by running koni SPSS with shorter bodies and more options for valving, but youre still left with a shock and sleeve setup that will eventually rust to hell due to low quality steel and coatings.

With these issues along with the price tag of a full koni/gc setup i dont understand why anyone would ever go this route over some of the other more adjustable, more universal (per user setup) higher end parts like Progress, KW, Buddy Club, and Tein Mono

 

Gotta agree. I ran these years ago and they didn't last me more than a season of time attack. Lowered my car about 1/2 inch so nothing drastic and they really didn't live up to the hype I've been hearing for years.

 

Funny, hundreds on this board alone run them in auto-x with few to no problems.

 

That may be however time attack and auto-x stress suspensions differently... you're not riding curbs at 100mph in auto-x for example. Switched to Tein RA's and several years later upgraded again to RR shocks and I experienced no problems with either of these set ups with considerably higher spring rates

 

I just installed the Gc/koni yellow combo on my Ep3 and it rides and handles like a champ!!! The lifetime warranty is alluring but I believe you have to have a shop reciept
or be the original buyer of the yellows.The only part that might scare some kids is
the install.On the mcpherson strut wich all i have ever installed them on you have to
gut the shock and reuse for a housing for the new cartridge and you might as well cut and shave down the old spring perch while your there for a inch or two more of adjustability..and you get to pick custom spring rates wich is probably wanna the best perks to this setup all under a 1000 bucks!

 

Waa waaa waaa Cry me a river!! if your putting this setup on a dd then its more than a enough for a teen ricer

 

Teen ricer or not, you need sufficient shock travel to be safe let alone have a car thats not a nightmare to drive. Theyre fine for stock height less an inch or so, but one the teen ricer wants to slam their car or just have a tastefully low ride height it all goes out the window with this setup.

To me someone who puts an improper length shock with a lowering spring floating around the top of it is a ricer.

And yes Im also talking to all the spec miata drivers

 

That setup is perfectly safe(when installed correctly)slammed or not and the ride quality is more than comfortable for a enthusiast or someone looking for a drop and a nice ride.


.......I hate feeling like I'm driving a skateboard

 

There aren't that many other companies making sleeves that work with a wide range of shocks (stock/oe replacement, tokico, koni, bilstein, and kyb) and are of good quality. Not to mention that come with good springs (eibach).

I've had this koni/gc setup on my car for 4+ years now. I've NEVER once had an issue with the springs not seating properly going from full droop back to a loaded position. In all of the thousands of miles of street driving and the ~150 AutoX events and few track events I've ran this setup on. Not saying helper springs wouldn't be nice, but for what it's worth, I'm not worried about it even the least bit.

I'll agree they aren't great for getting REAL low. But, I've had no issues with a mild ~2" drop both on 450/550 springs and 650/800 springs. I'd be comfortable enough to maintain the same height and use 400/300 springs..

https://honda-tech.com/forums/showth...2983251&page=5
DG-FNR makes a couple of good points, based on tests, for the Koni Yellows..

Again, I've had this setup on my car for 4 years. They were repainted by True Choice when they were rebuilt 3 years ago. No rust issues here...

This setup can be had for $700 SHIPPED if you know where to look. All those other companies can't beat that price for what they offer..

And you're Tein RA's are what, $1500? That's..... $800 more than what the Koni/GC combo can be had for. I personally wouldn't compare the 2 for that big of a price difference. I could even have the Koni's shortened/rebuilt using GC's and still be less than the $1500 RA's.

They are also fine to use with a ~2" drop and fairly stiff spring rates. I'll agree they aren't great for slamming, which is exactly why most people who want to slam their cars go for something like Function & Form and not these...

My car is not slammed, I think it may fall into your "tastefully low ride height" category though. And...no issues with running out of travel.


Oh yeah, and also the '91 Si I AutoX. Lowered a good amount with OTS Koni Yellows, Ground-Control sleeves, Hypercoil springs(450/550), and stock top hats. Nope, no travel issues or spring relocation issues on this one either..

 

i had koni's on my civic before and i loved them, yes i had a fully built suspension setup, not just off the shelf koni's and off the shelf gc's

i had koni's all have been revalved, h&r race springs 550front 450 rear with helper spring, stock civic front sway bar and progress 24mm rear sway bar...

i also ran stock top hats with no problems i never bottomed my car out, ive even jumped it 2 feet off the ground and it landed flat and smooth, i have many witnesses even a few h-t users that were in the car behind me i miss my koni h&r setup when i get more money to drop 1k plus on suspension im going to be doing the same exact setup it worked very well

here is a pic of my setup



and here is how low it was


not slammed at all, im not one of those to have their rims at 90 degree angles riding on the side of the tire crap ***** nasty

only reason i chose a single spring over an adjustable spring is because i can pick my ride height and stay with it, there is many spring perches you can buy from koni to change your ride height i chose mine and stayed with it no need to raise and lower the car and mess up camber and alignment angles
