Have you guys installed these yourselves? I've never done suspension stuff.

I did my spacer, z tube, exhaust, and sway bars myself.. but i don't have anything to compress the springs.

If you did this yourself, how easy was it? Do i need any special tools?

Yes, you do. I have the tool. I'll do the install for a fee.

how much o.0

Most shops charge $250-$300. I'd do it for $150.

i'll let you know. thanks. i'm going to do more research on how to do it.

No prob.

does anyone have issues with scraping? I don't want to scratch my shiny new exhaust :(

Yeah all you really need is a spring compressor to take off/install the springs on the front shocks. did you get the g35 or 350z versions?

Some links to help you out:

suspension DIY

Spring and Coilover Installation

you might also want a copy of the factory repair manual which comes in very handy when your doing anything to your car on your own.

and also remember...google is your friend

If i'm just doing the springs, do i need an alignment? Or is that only if i do coil overs

g35

ahh shoulda got the 350z versions but yeah you will need an alignment. without camber kits you will not be able to get it within spec. it will be close though.

What's the difference between the 350z and the g35 version? I haven't actually ordered them. I was going to last night, but decided to do more research.

Tein S-tech 350z (fronts are progressive, rears are linear) .7”/.6” drop on 350Z G35 drops will be higher
Spring rates in LBS 386/402

Tein S-tech G35(fronts are progressive, rears are linear) coupe drop 1.2"/.9"
Spring rates in LBS 358/274

stock suspension spring rates for reference:

non-sport suspension (G35 coupes with oem 17’s & 18’s): Front:314 Rear:342
sport suspension (G35 coupes 2005/2006 with oem 19’s only): Front:314 Rear:427

The G35 versions have some really soft spring rates for the rear as you can see above so most people go with the 350z versions. Also, the 350z springs installed on a G35 will give you a slightly lower drop when compared with the G35 versions.

but if i go with the 350z version, will the ride be super firm and uncomfortable?

do you have a link of where to buy these? i was getting them from b2autodesgins or something.

either way you go the ride will be rougher than stock but its not necessarily "uncomfortable" and just find the place that has the cheapest price. get some quotes from venders on G35driver

just ordered the 350z version. they'll be here tomorrow. w00t.

for a alignment, do i do that after the springs settle? or right away?

do it after the spring settle in a bit. a couple hundred miles or so

Got the springs in. At first when we lowered the car from the lift, it looked EXACTLY the same. We went away for 15 minutes, came back and it was much lower

Yes... i know they have to set, i was just saying..

I went down to NC over the weekend and put about 500 miles on them. I'm gonna get my alignment done this week sometime. It doesn't really seem to NEED it.. but i was told to do it anyway to prevent odd tire wear.

I had before and after pictures... but my phone turned off and won't turn back on, no matter WHAT i do. so i'll just take after pics tomorrow to show you guys. But i'm sure you've all seen it before.

I went with the 350z springs that viceversa recommended.

All and all i REALLY like the drop. It's a big difference. It'll be even better when i size up to 19's from the 18s. I definitely want to get wider tires in the back to make them flush.

lol, not my kinda low. But the whole VIP is not my style.

Not dogging it, I just wouldn't do it to my ride.

I want to go lower in the future, but since this is my daily driver, i'm happy with the change. It should hopefully sag a little more over time. The size up in wheels will help too.

Eventually i'll have coil overs and i'll go lower, but i'm happy with this.

Looks good bro! glad your happy with the drop. been so long since ive rode on stock suspension, so how does the ride feel compared with your stock springs?

The ride is very similar to be honest. It's a bit firmer, but cruising it's pretty much the same.

I can really feel imperfections in the road though. I could feel them before, but now it's much worse. That was to be expected though.

My friend drove in front of me yesterday and said that my headlights were giving him a seizure because my cars suspension is firmer. (clear lens swap on the projectors = lots of color in the cutoff)
