2005 Coupe, non sport suspension, OEM 17s, Stillen Sways (if it matters)

Hoping to get some experience advice on this issue, I'm planning to lower my car soon with some xmas money, and as I get closer to this eventuality I'm getting more and more confused by my research.

This car is my one and only, so it is driven daily, comfort is important, but the track bug has bitten me so I'd like to have a setup that is more capable than stock when taken to the track, but by no means has to be some end all solution from the handling gods.

There is a budget, which is keeping me away from pretty much all coilovers.

I'm not looking for a drop much more than 1", I scrape enough at stock height around here and would like to avoid completely bottoming out.

I'm planning to pick up a set of Tokico "blues" to upgrade the shocks at the same time.

Now comes my confusion, initially I was thinking that Swift Springs were the way to go, at least their website had convinced me as much. But after double checking my research I see that they are softer than stock, kinda putting a buzzkill on that whole idea. Similarly they are linear which (unless anyone has them and can say otherwise) I believe would impact my daily comfort.

So then I my judgment went over to RS*R springs, these are progressive, have the right drop and so on, sounded great. But these offer no increase in stiffness, further adding to my all out confusion.

I've dug around, searched and read, and don't find myself any closer to any sort of conclusion.

I'd be ever so thankful for some advice on this matter, I keep hearing good and bad things about the relevant Tein and Eibach offerings, should I go with 350z RS*Rs?
This thread leads me to the prior conclusion: https://g35driver.com/forums/wheels-...-rsr-tein.html

So I guess my question is are these better than Swift (like I'm thinking) or is there a candidate beyond these two which offers better results for my needs?

Thanks for your patience...

 

Go Tein H-Techs with Hotchkis Sway bars, it will offer a nice tight compliant ride.

Consider new sways as part of your package, they are just as if not more important then the springs.

 

well I have Stillen adjustable sway bars and am happy with those.

Do you have the H-Techs? If so are you using the 350z or G35 ones?

 

I have the G35 H-Techs installed, once settled in they are actually lower then expected. I have about 8,000 miles on them and the fender gap is about an inch. They are very livable for everyday driving, yet I hit the turns hard and body roll is almost gone vs. stock. I think the G suffers from serious body roll in stock form, something the 350z does not experience, I believe the sways are mostly to blame. I went with Hotchkis so I can recommend them, I am sure the Stillens are just as good.

 

Tanabe offers I believe 3 springs.. if im not mistaking.

NF210 is for people who are looking for stock feeling but with a drop... so i guess if you're worried about the ride comfort that would be a good choice.

 

Thanks for all the help so far, now I'm pretty much torn on going with the 350z H-Techs or RS-Rs

RSR 350Z linear springs .6”/.6” drop on 350Z G35 drops will be higher
Spring rates in LBS 345/417
Tein H-tech 350z linear springs .3”/.2” drop on 350Z G35 drop will be higher
Spring rates in LBS 358/375

The G35 swifts are looking too soft, as are the Tanabe's. And if I run the 350z Swifts Its looking like I'll scrape my front end to hell, and using Tanabe 350z springs would scrape up my whole car (pertaining to the areas I have to drive around at least).

So I guess its mostly down to the overall drop now?
1.1/1.1 with RSR or .8/.7 with Tein
the height on the RSR is closer to what I'm looking for, but could that be problematic with getting back into alignment spec? I've read that you're usually ok around 1", but also that anything over .8 will cause trouble...

 

go for the even 1.1 drop... i personally have the df210 i think it gives a nice stance :P
