Are these coilovers any good?

[Sydeways]

Anyone had experience with these?

Oh god yes...Ground controls are some of the best you can buy.

You just need good shocks to go with them ..Such as Koni yellows.

When you buy ground controls from an authorized dealer, you can order your own spring rates. But you need shocks to go with them.

I would go to ground controls site..To make sure you get what U want

[Sydeways]

How much do koni yellows run?

[Photonic]

600 ish ? =D But they are vastly superior to any entry level coilover's shock, they will last longer they are only 5 way adjustable but EVERY CLICK has a noticable change they are more precise and fluid than say your JIc's...megans...wtfever.

If you are really interested in Ground Controls theres a guy on Nissanroadracing.com who can hook you up, He does custom strut housings so you can use a full shock and not a strut insert...Sets you up with Camber plates..GOOD set of Konis and whatever spring rates you want for the price of your mid level coilovers.

megans are good too

[Photonic]

Fo the price range megans are definitely underrated by alot of folks..Hell..CodyW on Drift Mekanics uses megan products and he has had tv spots on Nopi (or was it Redline TV..anyway) . I will Buy a set of megan streets most likely because i have given up making the 240 a dedicated grip car.

ChukiDori..

Your serious? Your saying a fake coilover setup on a strut is better then an actual coilover? JIC's are great coilovers. Up there with Stance, etc. They are no Ohlins, but cmon. Ground controls aren't even close to the best you can buy.

if your going to spend 900 on this setup, get megans or save up and get jics or teins or something

How is it a fake coilover?

Coilover = A coil spring, over a SHOCK. A spring is a spring, And ground controls allow you to order whatever spring rate you want....just like with coilovers...a spring is a spring..Whats important is the quality of the shock valving which is difficult to control in mass production surprisingly. Ive heard you can have a matched set of JIC's MEgans etc with the same part number...And have different shock dyno readings on the SAME damping "click" setting. Worse even, The adjustments fluctuate and are inconsistant..depending on wether you reach the "click" coming from stiffer or softer..

Would you care to read Dennis grants "Auto crossing to win" and hear what he has to say about JDM mass produced coilovers for grip applications? He has shock dyno data also.

A 1600 koni yellow /ground control setup with camber plates Will be a much better road racing setup than "megans" or "jic's" or some taiwanese/jdm mass produced crap.

Unless you have to use them, I would buy a full coilover system. For cars like Corollas and Cressidas that use inserts the GC coilovers and perches are a good option, but even then for less work and about the same price you can buy Megan coilovers. Its all up to personal preference, but for the same price I would rather buy a complete setup rather than piecing together struts, perches/springs, and camber plates.

To top it off, using this type of setup that wouldnt have a threaded body means adjusting height would automatically effect preload. Threaded bodies used to be top dollar but now its pretty much the standard in full coilovers.

Decide for yourself. I dont know what your application is.


I've run hundreds of shocks on my shock dyno and the repeatability of shock adjusters is downright horrible on anything except the highest end shocks (and even these have their quirks). When you have the damping right, it's right - unless you do something to change the natural frequency. Changing the shocks to try and change balance is an act of despiration - or of a Stock class car, which has little other options. Highest end shocks ..as he will discribe are not JIC and megans =D but rather Bilstein..Koni...Ohlens...

Im not trying to convince you JDM coilovers are BAD! Depends on your application and price range...Im just attacking the "Do you really think fake coilovers are better rhan real coilovers" Which I dont understand...because A coilover is any coilspring over a shock...And its a trendy name to discribe a mass produced product...any coil spring over a shock is a "real" coilover...mass produced crap or not. But even with the Konis theres some variation in the shocks...But the valving is just real nice on them

KWs for the win

[Photonic]

Wow i get the feeling my posts seem a tad aggresive..

Anyway. As I was saying..A spring is a spring..spring A of a given spring rate behaves the same as spring b of the same spring rate. What is important is the shock. I believe G/C coilovers are good because of the versatility you have in Choosing a variety of high quality shocks ! =D

JDM coilovers are fine in this stage of the game, and the shocks are matched to the spring rates..usually..They just behave..Erraticly throughout their range of motion compared to Higher quality shocks. And You also run into more wheel fitment issues with coilovers than a stock profile GC setup being ..inverted monotube and all choosing the right offset or running spacers becomes important. I believe Shock quality is important because shocks only operate when there are Transitional loads..Which Drifting and auto-x have ALOT OF ..For road course use and road driving where there are alot of "steady" state corners and the car is not in a rapid state of transition from loading to unloading..Your entry level JDM coilovers are sufficient

ChukiDori..

Tylertell that to all the auto-xer's, lap times talk.

maybe not for drifting but auto-x, road racing they are hard to beat.

unless you are getting a moton (or comparable) at which point you are spending $$$ and competing in a series. (and you still see guys out there with koni's)


,,,,

do you auto-x, run at track days?

wouldn't these be a dream to set up lolol

Oh, well I wasn't talking about road racing. I am not experienced in that. So maybe its the best there, but how many people on here road race? Not many I would imagine. How many slide? A good amount. So I figured we were talking about the application they would be used most for.

I didn't mean to attack you. It just seems like a shock and spring combo is taking a step back from a full coilover setup. Like JIC, Stance, Ohlin, Zeal, etc.

Ive done a lapping day at Talladega Gran Prix and...other than that alot of spirited driving and reading..:( ..And Id like to get into Auto-x =D they have some up in Birmingham occasionaly...I know quite a few people who Auto-x

Thats the thing...It IS a full "coilover setup". A coilover is a coil spring...over a shock...Thats all it means. =D The purpose of buying a "full coilover setup" is because its easy. You buy shocks valved to match your spring rates and they bolt right on. Oh yeah you can corner balance your car with them

Entry level JIC's are crappy. The higher end ones are decent (speaking from statistics not experience) Iveh eard stance are good FOR THE MONEY..Ohlins are definitely fuckin baller status...so are Zeals. And megans are the BEST entry level coilover you can buy in my opinion. I know people who swear by them..And a couple high level grass roots contenders use them quite well. I will probly buy megans myself =D

[hellfire]

I have Zeals on my S14. Carina has JICs now. She also had the old Apex N1's, which are good shit. I personally can't tell the difference between the JIC's and my Zeals. Probably lack of experience. But I like the JIC's.
