just curious about these coilovers

i'm kind of interested in upgrading to coilovers from my current set up KYB AGX/ Eibach combo which i didn't change the upper mounts during the installation. NOt sure yet. check the link below, there is coilover systems for z32 K-sport, JIC or ??? brands and BBK kits as well, check under z32 then the brake section. they're offering Free Shipping as well. Any IDEA?

... what do you want to know about them? They're all brand names, so I'm sure they're quality.

But unless you track the car, coilovers are a HUGE waste of money.

the cheapest one is Nex SS Full coilovers $729. i only use my z for 1/4 mile, i hardly drive on the street but at least i have to drive my z on the street if i go to 1/4 miles. and my main concern is about the upper mounts, i think they're kind of worn since the car is 14 years old. so, i've been wanting to replace them, i checked czp.us, they have oem replacement kit that includes everything boots, bump stops etc.. which is $280 and i know the TEIN and Cusco has front/ rear pillow ball mounts for our cars but i'm learning toward TEIN which is a bit cheaper $306 for both. but not sure they work with KYB shock or not. if i have to replace, i wouldn't pay $$ for oem rubber or other similars. and i considered KYB/ ground control set up with TEIN solid upper mounts as well and i figured 399 plus 306 total gonna be $705 or so. i guess that the prices for coilover around $700-1K range is not bad for me. if i can get the full coilovers, i can sell my KYB/ Eibach. i'll be upgrading the turbos and increasing the power as well like my other post stated. so, i want to make sure about the suspension mods before i putting any of that power to the ground. i'm ordering stillen sway bars with the adjustable endlinks from Charles Park (powertrix.com) through tt.net under classified which is $399 for that matter.

"cheapest" is not usually a good thing when you are talking about z32 aftermarket parts.

well, i'm just giving a comparison between these coilovers, doesn't mean that i'll get that one. for the upper mounts i trust or like TEIN than cusco, cheaper is the 2nd but not always the case for me. should i use less expensive than CHEAPER instead.

Have you put in a bushing kit yet?

You might want to keep the stock shocks and just put in a bushing kit if you want less wheel hop and a tighter feel to your ride without sacrificing ride quality. Coil overs usually come with very aggressive spring rates which leads to very little suspension travel i.e. harsh ride.

Are you going with larger wider wheels?

Do you want to lower the car?

How much do you want to spend total on suspension?

Camber kit, various powertrix parts, coil overs, bushing kit....it adds up and you might not like the results.

My advice is find someone with the mods you think you want and either take a ride in their car or talk with them about it before you journey down this road.

I guess that you didn't read about what my other post said. if you want to read, here is the link https://www.zdriver.com/forums/300zx-z32-forums-7/time-get-back-z-suggestion-needed-25728/

Are you going with larger wider wheels?
I already got the Volk GT-C 18x8 front and 18x10 rear with yokohama ABS sport 245/40 and 285/35 tires on.

Do you want to lower the car?
I already lowered with eibach spring which is 0.8 all around if i remember correctly

How much do you want to spend total on suspension?

Already spent over $$$$ over a year ago along with brakes.

Camber kit, various powertrix parts, coil overs, bushing kit....it adds up and you might not like the results.

Already got the stillen front upper control arms, SPL V2 tension rods, Powertrix rear upper control arms(which is suck, chrome plating was peeled off just over a year old), SPL 8 piece subframe bushing collars and replaced the stock bushings with Energy Suspension Polyurethane which include Front lower control arms, steering rack, front/rear sway bars and endlinks (just the bushings), entire rear control arm bushings 18 pieces but 2 bushings didn’t use for upper control arms since I got the Powertrix one. As far as I know, I only need to replace the bushings from two locations sub frame and differential.

My advice is find someone with the mods you think you want and either take a ride in their car or talk with them about it before you journey down this road.
Thanks for advice.

I think you've said this before. What if you wanted to lower your car to make your wheels and tires fit perfect? Is there a better way to go?

Ground Control Coilovers. Fit the stock shocks (or any aftermarket shock you want), and only cost $400.
http://www.ground-control-store.com/index.php

It's [basically] what I have on my car - you can choose your spring rate, adjust the ride height just like full coilovers, and it's MUCH cheaper. With a set of adjustable shocks and ground control coilovers, you'll end up with the same capabilities as a full coilover system. Or you can use the stock shocks and save the in-car adjustability on the TT. Just a more versatile product, in my honest opinion.

Huh?

How is 400$ for the ground controls + 250 for the ebiach springs +300 for the shocks "much" cheaper than a decent set of coil overs? at about 1000$
Unless you mean cause he already bought the Ebiachs (then subtract 250.00$)


SS Tein coil overs
Ksports
HKS II
SPLs
and quite a few others have coil overs from 750-1300$ range.

Anytime you mix stock shocks with aftermarket parts you run the chance of severely shortening the life of the stock part. The Stock shocks sit in the middle of their suspension cycle when the car is on the ground. Coil overs have shocks that match the length of travel designed in with specific springs.

i do believe the "much cheaper" referred to a setup with stock shocks. and you can delete that $250 for springs, because if you had read the specs for the ground control coilovers, you would have seen that springs are included. so even with a quality set of aftermarket shocks, you are out the door for about $850. not too shabby.

Reading Comprehension FTW!

:::sigh:::

PLEASE don't respond to me if you don't know what the f*ck you're talking about, it only irritates me. As entropy said, $400 includes the springs. Stop trying to make yourself feel like you're intelligent... the result is actually making you look the opposite.

Get whatever shocks you want or use your stock ones until they wear out... most setups are less expensive either way you go. It only gets up in cost when you're looking at high-end shocks... but then the price is comparable and so is the performance and adjustability, so you're not losing out on anything. And there are a lot of people who have aftermarket shocks to begin with (like myself)... so $400 more to get height adjustability in addition to stiffness is FAR cheaper than buying a complete coilover set.

I guess i just don't see it

Where is the savings? aftermarket shocks + ground controls still equals same as Tein Super street coil overs. If you plan ahead you wont have to keep throwing parts at the problem to get the same results.

Oh, I am responding to you because its a forum, get over it.

If you read his post, he said he has already spent the money on the springs and shocks

So by your method he will have spent 250$ for springs,400$ for the KYB's and another 400$ for ground controls ... Lets say he instead got the Tien SS with pillow mounts to start out with for 1000$ Please explain to me how it makes Coil overs a big waste of money? Just becuase it's not the way you went doesn't make it any different in the long run on how he spends 1000$ Since he apparently wants Coilovers and even NOW if he decides to go with them it would only cost him a couple hundred more (after he sells the ebiach/kyb set up he has now).

So Keep on sighing and feeling all misunderstood but try to realize that just cause you did it that way doesn't mean its the only way to do it.

I enjoyed your pics of the Chicago meet, seems like a good turn out.


Oh and Entropy, did you read about all the other stuff he did to his suspension? Do you think he would ever stay with stock shocks, seriously, he said he has KYBs already.

I wasn't reffering to his specific setup, but now that you mention it, if he already has the KYBs he can use them. And since the springs come with the GC package, he can sell his old Eibachs, which will offset the cost of the GCs. So figure he only gets $75 for the Eibachs, subtract that from the $400 for the GC package, and his end cost for the coilover setup is $325. Thats a lot less than $1000.

i guess you just don't see what my point is. my concern is about upper mounts, ground control doesn't come with them. do they? so, at this point i gonna have to buy ground control + upper mounts, let's say 399+306=705. so, in my situation the price for the coilovers around $700-1k or alittle over is not bad, if they come with upper mounts. i think Tein SS kit doesn't come with upper mounts. the other kits like K-sport, JIC, SPL etc..do come with it. my first mistake was i haven't go directly to coilovers instead of shocks/ springs. i figured ground control set up won't save you, if you were in my situation because you have to buy ground control+shocks+upper mounts. unless you using stock shocks, minus whatever the price for shocks, you would save a bit but for using 14+ years old stock shocks ????? I can't tell for sure that i'll get coilovers or not.

you do have KYB AGX shocks already, right? you can use those KYBs that you already own with the Ground Control setup. you don't have to go back to stock shocks, and you don't need to buy different shocks.

honestly, if your only doing the 1/4 mile you dont want coil overs anyways. they are for reducing body roll and aggressive driving all around. in a drag race you want squat in the rear but without any hop so you can get the proper weight transfer for better traction. i would honestly say for the things you are using your Z for you have a great setup already. also, true coil overs are much more expensive than the ground control your just doing the math really stupidly and not staying open minded.

i may be wrong at this part because i already bought KYB shocks. ok, let's put it this way people who hasn't buy anything yet and if they buy aftermarket shocks+ground control+solid upper mounts (the one come with most coilovers) if they want it. let's say KYB $380 + GC $399 + Solid upper mounts $306= $1085 total. so, at this price they can get a good set of coilovers for more or less.

i was talking about you specifically there. in your case, it would be a cheaper option because you already have the KYBs. and its a cheaper option for people who don't want the solid uppers. i'm not saying its the only option, or even the best option, just an option.

Goofy was trying to say that in YOUR case, it would not save money. i was just trying to point out that he was incorrect, as you already own the shocks.

sigh.... i really don't see where the confusion is coming from...

Mostly 1/4 miles?

Then you should consider a solid rear end which would mean neither what you have or coil-overs.


My argument was that coil-overs are not much more expensive than kyb+ground controls.

the other argument was that instead of going for two seperate things you still wanted pillow mounts and ride height adjustability you could still just sell what you have KYB+ebiachs and buy a decent set of Coil-overs that come with pillow mounts i.e. Tein, ksports and such.

In the end the money comes out about even.

But if you application isn't for autocross or track use other than 1/4 mile you might just want to go with a solid rear end for drag racing.

Goofyz, i'm not saying that you're incorrect, you're right about price comparison between coilovers and kyb/ ground control set up.

I'm saying entropy31 is right about this part

i know i can still sell kyb/ eibach springs after i get coilovers. but this is not my priority for now. so, i put it on hold and will do the engine mods first.
