Best springs...
 

I'm looking to drop my car a little bit. But don't want to pay for coilovers because I think they would more then I need cuz I'll probably never go to a track. Sooo, what springs do you all think would be best? I'm keeping my stock wheels for awhile, probably gonna put spacers on to get more flush, and the car is only going to be driven in warm weather. Its getting parked in a shop in winters.

Eibach for about an inch drop. If you do lower you will need expensive front and rear camber kits.

seems like H&R's are popular too here... i'd prefer to run new dampers if i get lowering springs... keeping my fingers crossed that hitachi (tokico) does D-Specs for us.

Yes and at a 1.2" drop you are going to need front and rear control arms to correct the camber. With the Eibach you can probably get away with no camber kit with minimal camber issues. I hear maybe just for the rear...

I have Tanabe GF210s on mine... I like them!

I'm on H&R lowering springs + H&R 20mm spacers F/R and I only used the SPC rear camber kit (toe bolts included but not needed/used) to get a final camber alignment of 1'5'' front and 1'2'' rear. Toe is 0'03'' Front and 0'08'' Rear.

But I'm really waiting for a manufacturer (ie: Koni yellow) to produce adjustable shocks. The stock shocks are too soft for my liking.

The h&r's look really good. But with the camber kits its almost in coilover range. But I hear eibachs are real soft and cause a bumpy ride. So I going to keep waiting for replies. Havnt heard anything about teins yet? I'm leaning towards h&rs right now though.

I've had eibachs on 2 of my previous cars but they got super bouncy over time and handling was adversely affected. I swore to never go with eibachs again. I am also looking for something that drops ~.5" f/r so i don't have to use a camber kit. I've had excellent results with h&r/neuspeeds in the past but the h&r seems like it drops a bit too much and neuspeed doesnt make springs for nissans.

The Tein S-Techs provide a very nice drop (.9 front/.7 rear) and upgraded handling without dropping so much as to necessitate a camber kit.

We have some in stock and could get a set out to you today if needed :)

its probably not the springs that caused the bounce but shocks/struts which prematurely wear over time..

H&R's are the best choice for me..i dont like alot of gap and the spings ride like stocks...i would of went with a linear set like Swifts but i contacted them and they have no plans on developing springs for the 370Z..

I'm also looking at a small drop, but mostly want the best ride and handling possible. I know it can't ride like a caddy and handle like a porsche, but as close to both as possible. What setup would give a smooth comfortable ride, as for as springs, shocks, coilovers ? Sorry for the super noob question; i've got the sport pgk, hotchkis sways, and 20" rims and tire setup of 255/30/20 front and 305/25/20 rear. I had eibach pro kit on but it was bumpy as hell, i thought taking them out would help but no. Maybe tires with more profile would help, somthing like 255/35/20 f. 305/30/20 r.... Sorry for highjacking this thread for a min. It's driving me nuts... any help is appreciated. Thanks again ......here's a pic. with the stock spring setup (no drop)

Its kind of hard to gauge your defintion of bumpy but you only have a couple other options...teins, tanabe, h&r's etc..personally i prefer the h&r's and i've tried them all...you might want to try a kw coilover setup..they are very street friendly and adjustable to whatever height you want..

Bumpy compared too stock spring/tire setup, i've heard the KW's are a nice setup. Do you think different tires would help ?

Yes, larger profile and less air pressure helps ease the ride..

Not true. I swapped out the eibachs with neuspeed/h&r and the ride was perfect again on same shocks. Eibachs are known to have this problem (atleast in the honda/acura community) and i was one of the test dummies that found out the hard way.

I've had a very good experience with H&R's with my S2000 with stock shocks. Drop wasnt extreme however, <1" drop.

I was leaning towards Eibach with the 370, but with the reports of the springs going/feeling soft after some time, I've decided to drop the car properly and go with KW coilovers. I originally was going to go just KW V1's with just height adjustibility, but in instead of taking my chances with not liking the ride dampening, decided to go KW V3's.

I hadn't considered H&R's for the 370 since the the drop just looks too extreme for the roads up here in Canada. I'd probably be scraping all over the place!

i've had eibachs on a few of my cars and no bounce..the pro-kits..they ride like stock at least in my experience..just not enough drop..

ironically the neuspeeds i installed in my prelude many many years ago was bouncy as hell and undulated under moderate driving conditions. this was on a car with less than 3k miles. quickly swapped them out for TEIN HA's which were considered new and cool at the time.

you really need to look at the spring rates, linear or progressive, and amount of drop, amount of bumpstop you cut or replace, and your wheel's offsets (wheel rate) to get a sense of what to expect.

on that note (i dont plan on lowering my Z with lowering springs but) what is the spring rates of the stock springs? that is where i would start the search if i was looking for springs.

... because some of you asked about a picture from a z with eibach and stock wheels. here it is.

I thought Eibach made Nuespeed's springs!!

no....h&r and neuspeed are the same company, but neuspeed doesnt make parts for nissans.

^^^"h&r and neuspeed are the same company"

Where did you hear this?

I think you are wanting to go with a Linear spring on the 370Z. I am going to try RS*R Linear springs Ti2000 from the 350Z, they claim a .6" drop and Front Stiffness: 6.2kg/mm (345lb) Rear Stiffness: 7.5kg/mm (417lb) so hopefully they do well! I'll let you all know soon.

yah, H&R oems to Neuspeed. the neuspeeds for the prelude was made by H&R at least.

Just something i've known from being in the community for 10+ years now. It's common knowledge that most people are aware of. Feel free to research if you're doubtful :happydance:

I used to own a speed shop, and distributed both of those products, and they came from different places - different owners.

Actually, I was commenting that they were the same company, which I don't think is true. Sure maybe Neuspeed has H&R make their springs, but they aren't the same company, which is what I was questioning. I did a quick search and found nothing that said they are the same company.

H&R is a German company and Neuspeed springs are advertised as being made in Germany. I just knew that Neuspeed did not produce their own springs and couldn't remember since the last time I looked into it was in 1998.

BTW, They are not the same company. ;)

damn....maybe i'm off then. but they were some how affiliated for sure in the past. Like kenchan said, i remember back in the days when they were manufacturing each others' parts even if it was for a little while. Thanks for the clarification.

tanabe's and the eibachs will give you the most bang for the buck. Both companies have good quality as well

Wrong. Neuspeed and H&R are NOT the same company...

:happydance:


In other words... Tanabe ftw. I love their springs!!!!

uh.....selective reading much?

I thought they were a little lower? 1.5 or so.

Could anyone clarify whether the Tein springs are infact a 1.5" drop or whether they are as stated on their website specs - NISSAN 370Z

Based on the website specs being .87" front and .75" rear - would i need to run camber kits?

Also does anyone have the approximate drops of the H&R springs?

Any help is appreciated.

They are as stated, .87" front and .75" rear, H&R are lower at 1.2" front and 1.0" rear.

I don't think you need a camber kit with the Tein, and with the H&R you will probably need one, or for just the rear. Remmeber the lower you do the more likely you need a camber kit as the camber will be more negative.

Hi, guys!

This might be a silly question. But, I want to know which one is better between the Eibach pro kit and Tein s-tech. Please let me know that before ordering. ^^
