I'm currently lowered on rs-r springs, but I'm looking for somthing that makes the car sit a littlle more snug. Whats the difference between these 2 springs? I've done my research!!! The tanabe gf210 lower the car a little more than the eibach if i'm not mistaken. Why do the eibach's cost more?? How far off will my camber be after an alignment? Please help....Thanks!

 

I have the Tanabe NF210 installed on my Base 2004 350Z and have the alignment data of before and after. Just PM your email address and I can email it to you tomorrow. As I have the data on my work PC at work.

NF210 isn't lowered much, no where nearly as much as the GF210 springs he asked about. I have the GF210 springs and it sits really low. You won't be able to achieve stock alignment specs without buying camber/toe adjustables. Great springs though I am very happy, handling is so much tighter and more crisp, yet the ride seems a little better too honestly. If you want to lower your car and stay stock without buying alignment gear, get the Tein S-techs.

I hear the Eibachs feel soft. Dunno, they advertise a higher spring rate...

 

What about the eibach's? Lots of members have them. I'm getting the aerosync bumper installed this friday, so I think the tanabe's might be to low...Would eibach be a good choice??

 

i have a set of eibachs and i never put them on thought about it but didnt want to void the tire for life warrenty i have the the dealerhip i have if you want i will sell cheap i have had them for like 2 years and just never put them on

 

Is it the Sportline or the Pro Kit?

 

prokit

 

Yea I think the pro kit is the one im looking for...

 

How does the eibach prokit do at the track..Or off the line in a race???

 

If you mean "track" as in anything other then drag racing, neither spring is very suited. Though the prokit's do offer higher spring rates and less progressive coils for a higher inital spirng rate vs the Tanabe's.

Eibach 350Z progressive springs 1”/1” drop* on 350Z
Spring rates in LBS initial/final front 296/384 initial/final rear 316/421

Tanabe GF210 Series 350Z progressive springs 1”/1.2” drop on 350Z
Spring rates in LBS 336/375 (only peak rates are published, softer initial progressive rates unknown)

For the track, I would only consider a spring that is NOT progressive (if we can even say that because to many of us, they are not stiff enough) spring choices would be,...

Tokico D-spec springs (linear)
375/375 1.2"/1.2" drop on 350Z

RSR 350Z linear springs .6”/.6” drop on 350Z
Spring rates in LBS 345/417

Hotchkis 350Z Linear springs .6”/.8” drop on 350Z
Spring rates in lbs 340/330

 

I'm curious what the problem is with your current RS*R springs. You just want the car to sit lower? Or you want better handling?

 

Correction my friend the Tanabe GF210 are 1.2 in the front and 1.0 in the back. And the NF210 are 1.2 all around. How do I know this, my cousin has the GF210 and that was stated on his springs. And my ride is more lowered in the rear than his. And the fronts are the same height as his.

 

i still got that prokit let me know if you want it or i might have to put it on once i get new tires

 

ok, I must have misread it before you are right the NF's are 1.2 all the way around. GF's are 1.0 front and 1.2 rear. NF's are softer if you want ride quality, they also look linear in the picture where the GF's are progressive. Not sure though. Nice catch.

 

make sure you do a little research before picking up those eibachs, I've heard people talk about problems with sagging, and making the drop excessive.

sorry ryanmac, not trying to bust in on your sale here but I'm just throwing some information out.

 

I would stick with the RS-R's.

I have them with Koni Yellows and they are great on the track and ride very well. Becareful when going too low because you will have to invest in new arms to get the camber decent for daily driving.

 

Here's some pics if you need a little visual ref. Tanabe GF210's about 4 days after install. They have settled a lot more now and probably has thrown my alignment off a bit as well. The rear camber was pulled in right to the OEM max -2.1 & 2.0 respectively. The fronts? Forget-a-bout-it....They're at -1.5 and -1.7. Hope this helps a bit..

Also, I can try to get a pic from rear showing what my camber looks like now..

 

For some reason it never really droped my much??? I'm running 245/40/18 in the rear and there is about a 1.2 in gap in the rear...The fronts fine???.....So basicly eibach's suck at the track right?

 

Well, the RSRs are only a .6" drop front and rear. Look at a ruler, .6" isn't very much. I wouldn't say that the eibach's SUCK but there are definitely better choices (for high performance driving). The GF210s wouldn't be drastically better. For performance, the big difference is progressive spring rates vs. linear spring rates. Progressive springs will make your car do some funny things at the limit, especially if you're driving on a rough/uneven surface or on a course with a lot of camber changes. But for the street, a progressive spring is just fine, and will yield a ride more forgiving than a linear spring. If you're just driving your car on the street, and doing maybe an occasional autox, I'd highly recommend the GF210s. Doesn't kill your ride, the drop is just about right (if you want a car that sits noticeably lower than stock, and the handling is still pretty good. Actually, I autocrossed on them for a whole year, and I'm just now switching them out for a linear spring (Ti2000).
