lowering an 1in front and 1.2in rear
I just got tanabe gf210 springs and will be doing an install soon, I know I will need an alignment but can I still be in spec with this drop? or would I need rear camber arms?
thanks

How far your out of spec will dictate if you can justify the cost to correct. If your going to only correct the rear you should consider getting the SPC kit with arms and elongated toe cam bolts since changing camber also effects our toe.

Beyond .8" is where the law of averages among car's that have been on the rack and checked most often are out of spec on at least one end of the car if not both. And then it becomes are case of how far out you of spec you are vs the cost to correct vs how how much you think those specs will effect your tire wear.

I am thinking of getting Tanabe GF210 on my 07...is it true the 06 and 07 is not as low as the 2003-2005 so the drop wont be as noticeable as the 03-05 drop? I dont want to get Tein S Techs on my 07 and not notice a difference, ya know? My main goal is to improve handling and looks, and I want a stiffer suspension, steering wheel feels sloppy now.
I liked the Tein S Tech on my 04 but wont get them if I wont notice much of a difference on my 06. I love the drop on the Tanabe GF210 but dont want to have to get a camber kit and have tire wear issues.
Help? I need to make a decision soon...

The GF210's will lower more then the S-techs. But they are softer springs and they are progressive, which won't work to to excise the steering wheel slop you say you have now, nor will they feel as stiff as the S-techs.
Your oem setup now has the following stiffness on linear springs.
314/427 (do not look so hard at your rear oem rates as much as the front rate)
Tanabe GF210 Series 350Z progressive springs 1”/1.2”
Spring rates in LBS 336/375 (only peak rates are published, softer initial progressive rates unknown)
Tein S-tech 350Z springs .7“.6“ (fronts are progressive, rears are linear)
Spring rates in LBS 386/402
Notice the number of closely spaced coils in this picture of GF210 350Z springs. These springs will have a wide spread between their published peak rates above and the softer inital rates courtesty of all those closely spaced coils.
Look for the same thing in this picture of S-tech 350Z springs. Notice that the front springs are progressive. BUT, only 1 maybe 1.5 coils will bind to effect rate change. Rear's are of linear.
If you have to have a 1" drop amount and your only wanting to be on shocks and springs and your still interested in performance, IMO the Tokico shock and spring setup is the way to go.
Tokico D-spec shock & spring package
350Z - DSK512 - 375f/375r - Linear Springs 1"/1"

So your saying if I'm more performance oriented I should go with the Tein S Techs over the Tanabe GF210? I just want a decent drop but better handling because I will be road racing the car...in about 10 days. Thanks.

Every place that list the specs are as follows.
Tanabe: Sustec GF210
Type: Linear
Front Rate: 6kg/mm (335lb)
Rear Rate: 6.7kg/mm (374lb)
Front Drop: 25mm (1in)
Rear Drop: 30mm (1.2in)
Where are you getting your info on the GF210s being progressive?
edit: after further research I really don't know if you can catergorize them as one or the other.
Here's a post I got from Revolution Motorsports

The Gf210 cil spring is geared more towards performance and track use due to its more linear rates and higher spring rate, but is completely suitable for daily driving.
Regarding progressive and linear rates, there is a lo of misinformation on the internet as to what is better, why and what to look for. Many people tend to ask "Are they progressive or linear?" For a standard coil spring that mount to OEM style shocks and struts, they cannot be one or the other.
Standard automotive coil springs (with the exception of fixed diameter springs for adjustable coilover suspension) are both linear and progressive. For drivability and ride cumfort, a portion of the spring uses a progressive rate, while the majority is linear.

But i am not looking to improve the handling of my car,seeing as my it will be used as a daily driver and not on the track. So the GF210's seem like the best springs for me, but i am worried about having to get a camber kit, which i would like to not purchase seeing as they are much more expensive than the springs themselves.
So my real question is....Is it necessary to purchase a after market camber kit for a 350z in order to install the Tanabe GF-210's and archive the 1.2inch drop. W/o having to deal with all the problems with alignment that i have heard?
Note: i have called several shops how much it would be to install springs and one very meticulously cautioned me about lowering the 350z more than 1inch and warning about all the problems i will have and how it is a must to purchase camber arms as well. This really had an effected on me and now Im rethinking wither i should lower my car at all.
Second note: he mentioned it was for an 05 350z
THANK YOU SO MUCH IN ADVANCED FOR YOU HELP !!

so only a rear camber kit is needed? And if i were to get coilovers and adjust them so that they are still in spec. (such as only droping it 1inch) instead of getting springs would that allow me to to keep the OEM cambers? b/c it would be about the same price just to buy the tien basics instead of the springs +the rear camber kit.
thanks
