Well,.hunting around on EBAY and I'm sure if you've typed in "350Z" you might have seen em. the ST Lowering springs!??

I guess I'll be the Guinea Pig for this,...I ordered them and they we're only $115+shipping--->normally I look @ price as quality..but then again..there are some products that out perform other HIGH priced more houeshold named products--ie.SPoon products/TRD products etc. that are Great!

They lower the Z 1.80 inches frt & rear---he said"It is based on the Eibach design & will offer a more aggresive drop then the Eibachs"(.08 frt & 1.30 rear) and I think the eibachs won't even show much of a drop---I'm not really going for a Super Track or all out Auto X'd car(which the Z already handles pretty stiff)...just mainly a "looker" w/ engine mods(once released) that will back it up.None so far but ECU will probably be the first mod if they ever come out w/ one I'll get.

They have sold 3 sets and have had no bad comments @ all...I guess its just one of thopse things where once the name gets out the Quality gets out and then They will "BLOW UP"--you gotta start somewhere right?

I'll post pic's and give a run down on ride quality as well..once I get em on!I should have my Wheels among other things once I get em on.

Lemme know what ya think.

115 for all 4?? sweeeeet! i was thinking of lowering my z as well. let me know how those spring are...cause i'd go for it for such a deal! also, do you need to replace the shocks as well when you replace the springs? just curiouz!

 

I'm sure w/ that drop--some say you might after a few 1000 miles...but all my cars have been lowered w/ normally Coilovers...and never replaced the stock Struts--Never had problems---only thing might be to get a Camber kit once one is released.But I never had those on my cars ether---normally had pretty good tire wear!

I'll let everyone know!

 

I saw those on ebay.... but damn 1.8" ?!! that's an aggressive drop!

Over time this will definatley affect the struts...

Please post pics when you get them installed... I'd like to see it!

 

Might want to hold off on the lowering springs unless you are getting adjustable upper control arms. A 1.8 " drop will give you close to 2 more degrees of negatice camber. One inch is equal to 1 degree of camber change on the Z That is way to much negative camber for anything. Also the drop in ride hieght isnt nec the way to go as far as the suspension would like it.

 

LISTEN TO dwnshift!!!!!!!

ok, what is the "negative camber"? does this mean that you aren't going to be able to turn as far? how would installing these springs be bad? what can happen??

 

My $.02

Listen to dwnshift!

Not only will the camber be effected negatively, the roll center will be lowered BIG TIME! Thats the point about which the car rolls. You're increasing the distance between the CG & the RC too much. The car WILL handle like crap. I learned the hard way with my Lotus. Lowered 1.5",with adjustable spring seat Spax shocks, added adjustable A-Arms, quadrupled sway bar rate, increased spring rate 25%, and it handled MUCH worse! Rolled in corners like a........Yugo! Raised it back 3/4", magic! Better than a go-cart, no bottoming, and it still rode smooth!

I'm over simplifying, read Carrol Smiths books. Specifically, "Tune To Win"

Now, getting rid of it's high speed(100+mph) trailing throttle oversteer is another story

 

Do you think the .8 drop from Eibach is too much ?

 

I think eibachs is a great drop for street use.. I had Eibachs on 3 other cars and I have no complaints...

 

It is when your wheels flop outwards. like / \. So called butterfly. Its mostly happen when you lowered your car. A well adjusted negative camber can help on your cornering, but too much, it will have much negative effect. And also for daily driving, your inner tire wear will be unbalenced than the outer. With adjustable camber kits can help to reduce the negative camber, but not sure if they are any out there for the new Z yet.

Correct me if I'm wrong anyone. Dwnshift?

 

Excessive negative camber will also screw up braking. See SCC article on their modified Z. Here is a cool pic showing what we are talking about:

 

well,.what sux is,..
1:they are on their way,..

2: I've had 2 previous cars lowered on coilovers(one SKUNK2's and others we're Ground controls) and I mean they we're pretty much slammed!!!! way more then 1.8"( the max they normally lower is 3"---& I had them almost all the way down(not Ghetto/stunna low) but on my RSX-S,.I had 17" VOLK TE-37's w/ 225/45's on it and the car sat right pretty much on the tire and put about 7k miles on them before I swapped front wheels w/ the backs,..(just to be safe) and the damn Tires still looked Brand new!...and had the front coilover almost maxed out too!! It handled GREAT!Maybe not AutoX great but Street was perfect.

My old GSR w/ the GC's on it--had 18inch Racing Harts(215/35's) it and I had them maxed out a little too low @ first but raised up because of Scrubbing(18 inch wheel remember on a Integra)

I will def jump on a camber kit as soon as one is released just to be safe-these tires aren't as cheap as my old ones we're--but my old cars by the way--I NEVER OWNED a CAMBER KIT FOR EITHER CAR!
I think this will befine,...Thanx for the info guys,..but DwnShift is right,....but mine is not going to any tracks or **** like that--just your basic Cruise Z(w/ a little gettin' on it).

I'll let everyone know how it is

as far as the Eibach's,..I promise you will not even tell there is a Drop on those!!!! TRUST ME,..the ridemight be improved,..but if you want to lower your Z,..them Eibachs aren't gonna do much..so I wnet w/ a lil' bit lower drop! 0.8 isn't ****---1.8 is @least you know its an inch+.
AS far as other people owning Eibachs on their other cars--I bet the Drop was more then damn 0.8...I've never seen that I don't think on any Eibach set..most people want a 1"+ drop or more
and no my tires aren't gonna be all spread apart from the negitive camber--if 2"+ on my old cars didn't do it,..a damn inch damn sure won't look like a really bad negitive cambered car!

 

With the Z 's suspension you gain more negative camber under compression......
So if you start with a 2.5" ride height and have a -1.5 camber angle...... under comression or loading you gain more neg......IF the front dives down under compression 1 " you will gain another 1 degree of negative camber.
So basically what happens is you end up riding on the inside of the tires all the time........
This is killing yours contact patch............it kills the cars overall grip and escp under braking.

You know your sh*t! This stuff is VERY hard to explain as it is VERY complex. I think Mr Fairlady does not understand the difference between a McPherson strut suspension and a multi link suspension.

Who was it that said "For every action, there is a re-action"?

 

Yep,..your probably right about the diff suspensions(I don't know much)-but once again my other cars we're not track cars either.....but either way nothing I can do now!Like I said not a track car @ all,..and Braking--hmmm,.I hope my *** isn't go fast enough into something that i would have to Stomp the brakes anyway,..but ya never know?

I'll give them a shot--wonder what everyone w/ their TEIN's,JIC's and HKS etc Dampners are settin their height @ then,..I see a few people have those types of Coilovers??The Z already understeers so this will probably make it worse to you Track guys,..but on the street--I don't catch myself understeering down Idewild Rd(my street) much-so I'll be ok--I'd make it oversteer aka. Drift if i want to and thats about all I care about--hardest part is find parking lots big enough to mess around in

I have a guy helping put them on so its free,...I try them for a few miles check the tire wear and Handling and give a conclusion--


THANX GUYS!

 

I dont know much but................... MR fairlady has a nice choice in the ladies............
WHO IS THAT?
UNREAL!

 

I say good for you MR Fairlady. You want you’re car low, so that’s what you’re gona do. You will find out what’s good or bad for you and you’re car.

One thing’s for shore, you’ll probably wet you’re pants when you see you’re Z dropped almost 2”. That will keep you jazzed for a long time.

True you do generally get what you pay for.
And you could mess you’re car up.

 

True,....I wouldn't think it would Fu*k it up for good,..but if its bad,.I'm sure I'll know,.otherwise--i think it'll be cool!
heres a pic of what I'm guessin my rides gonna look like!Skidazles car some one photochopped lowered and @ stock height w/ the 19"s same as mine!



DWNSHIFT--
that is "BRANDY"--or Brittany Daniels from : JOE DIRT!!!

SUPER HOTTIE!She loves me!

cue music: Bey baaaa eeaaaaa ee yaeh yeah!! ohhh I get Chills when I'm w/ yoooooooooooo!

I was looking at those springs too......... they came out of no where

These guys are all right, but maybe taking it too literally. Go ahead and try it out.....its not hard to swap them back out if you really need to. Measure the height before, then drive around a week and measure it again. IT will sag sag sag but then stop. Check our tire wear on the inside weekly (maybe even get a depth gauge). It should be "ok" for a while, but just keep an eye on it. Some day down the road pick up a camber kit. Ah one more thing, cut 1/2 your bump stop off the stuts cause they may bottom.


My last car was daily driven for years at 3" drop. And to shows at 4" drop. I had aftermarket struts but they were NOT for lowered applications. I parted out the car and sold it all for what I paid for it Of course I did run a camber kit but it was still out 1deg.......not an ounce of tire wear.
