is ground control suspension worth it? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

driftfreek · 10-23-2007, 12:58 PM

i heard about ground control suspension and it sounds pretty cool, the problem is that i couldnt find out the springs rates, how stiff could one go with GC? any info...?

DP_Michelle G · 10-23-2007, 01:02 PM

you can go as stiff as you like but tje problem is going to be with what shocks and struts you use

*ManoNegra* · 10-23-2007, 01:02 PM

You can get them with custom spring rates (Eibach). Preferred suspension set-up of most auto-xers alongside quality shocks. What I plan to do in the future for the S14.

MavericStephenc · 10-23-2007, 01:03 PM

I wouldn't do it.

spend the cash and do it right the first time with a nice set of coils. a friend of mine learned the hard way.

how the hell did he learn the hardwaY?

GC + Koni is better than anything one piece ive seen.

The only piece from Japan Ive heard have held up to racing over here and

are comprable are Zeal pieces.

You can use KYB in a pinch ands its ok, or Koni Adjustable.

But the real koni with GC is better than JDM stuff (WHICH IS MADE IN TAIWAN)

there stuff is ok my dad uses it on his m3 depends largly on the shocks you use with the package

*ManoNegra* · 10-23-2007, 01:09 PM

Well for me after following most of Wiseass' suspension threads and others with road racing and auto-crossing experience as well as having previously had average quality coilovers in all my former 240s, I think it's time to give GC + Koni shocks a try.
I want my S14 to ride like those slammed BMWs I see driving around.

driftfreek · 10-23-2007, 02:48 PM

konis r the best shocks/struts out there huh? but theyre expensive. like 700 bux, plus GC 350 bux, you mind as well get coilovers.right?
the shocks that one could get would be based on your spring rate right? for example u cant get a cheap shock that is not going to hold that much spring rate or else it will blow huh? are konis n kybs or someother brand going to be able to handle such stiffness?

Konis and the like can be revalved to basically whatever your heart desires, so, yes.

bigOdom1 · 10-23-2007, 03:00 PM

ground control has their own reccomendations for each car they have parts for. they also sell custom spring rates that you ask for. i like mine just fine and run them with the yellow koni sports. all to GC specifications.

Tearlessj · 10-23-2007, 03:05 PM

You shouldnt say "minus well get coilovers". If anything they are just as good if not better then some coilovers. It a pretty nice set-up.

firelizard · 10-23-2007, 03:06 PM

Don't bother.

Might as well just get a coilover system where the damper and spring are matched to work in unison, and made just for your car. It's not like proper coilovers are that much more money than high quality struts and Ground Controls.

It's not that GC is a horrible system, but what's the advantage? Penny pinching ftl.

PRADOgy · 10-23-2007, 03:21 PM

I think i seen some ground control's for sale at BIG LOTS ^__^

fromxtor · 10-23-2007, 03:20 PM

More like tuned suspension ftw!

DP_Michelle G · 10-23-2007, 03:25 PM

hit up drift freaq he had some for sale not to long ago

Dude just get a good set of coilovers.

DP_Michelle G · 10-23-2007, 03:48 PM

GC's are good if you have the time and know how to set them up

Thank you! Someone who knows what they're talking about!

I've had this conversation recently with Wiisass. Pretty much all of these Asian coilovers are just marketing garbage! With GC you have your choice of Koni or Bilstein shocks. I would only pick from those two shocks out of the other options GC offers...I think they offer Sachs too, also top quality stuff. If you don't like the Eibach springs you can put in some Hypercoils. These Asian coilovers never put up any shock dynos, and when they do they're not pretty.

drift freaq · 10-23-2007, 04:52 PM

Man another thread with dumb ass shit spread by people that really don't know.

Steve Shadows hits on the nail head! Any fool that is dissing a Koni GC setup does not know a thing about suspension. The only advantage that JDM coilovers have is they are preassembled. Oh boo hoo you can't take the time to put collars properly on a dope ass set of shocks.
Fact is if you really want a nice setup? Koni's and Ground Controls are fucking sweet and won't cost you anymore than the ok lower budget coilovers. I try out suspensions, for the sake of checking them out. Its why I have a set of Ohlins with Apex springs on one of my cars right now. It also why I am checking out a set of KBees. You know what though? I am building a set of Koni's with Ground Controls because they are the shit plain and simple. Either read up on suspension, or STFU. Especially if your dissing Koni's and Ground controls.

driftfreek · 10-23-2007, 05:04 PM

how much did you guys pay for konis and GC? i just called and they told me thats 1000 bux, tax included? spring rate like 400.

thats abotu right.

but what fron dampers?

run 400 front 300 back for grip on street tires

400 front 350 rear for r comps

400 is highest you can go iirc and still have 2-2.5 inches of lowering ability with the sleeves.

LIES!

I have 450's on my rears. Fronts probably could handle a bit more, but I'm on 8611's now

I wonder what the DSG car uses? He had off-the-shelf yellows in back last I knew.

In the end: Koni Yellow + GC will outhandle pretty much every JDM coilover out there, and 100% of the pseudo JDM stuff.

im REALY glad there is someone here with proper brain matter. All the coilover sackriders should read a bit on proper suspension setup.

Ya steve but the imposter wants to think 400lbs is weak when actually its right around 8kg and 300lb is close to 6kg. i.e. same as most coilover setups people run.

bigOdom1 · 10-23-2007, 05:09 PM

i dont remember what i paid i have had them since 2003

OK so it looks like someone is almost stealing your name here Dave.
Drift Freaq has lots of experience and is proven knowledgeable over the years.
Drift freek has yet to make a reputation for himself around here.

choose wisely.

You can definatley go over 400 my buddy just bought a GC/Koni setup for his E30 and GC had some springs for that chassis that were up to 800 lb/in

smacks forehead

I know you can go to like bazillion (800 or iirc even higher)

OK GUYS!!!

you too aceinhole!!!

not lies lies!

but what GC told me is that for the KYB shock or the direct bolt on adjustable Koni shocks the spring is actually phsycially longer if you go over 400 or 450 I cant remeber right now.

Im pissed off if the guy was confused and just jacekd me off like that

either way I only wanted 6 R 8 F, so 400 F 325 R is fine for now.
