DIY: 370Z Lowering Spring Install

yellogixxer · 09-16-2012, 06:10 PM

Did my Swift spring install yesterday. No air tools, so I took the strut assembly to the local Mr Tire and they changed the springs out for me for $70 bucks. Well worth it, in my opinion. Thanks for the write up. Rep +1.

Looking Nice!

Have you driven it much yet? Ride Comfort?

yellogixxer · 09-17-2012, 03:38 PM

I've driven it a bit. The ride is very comparable to what it was with stock springs. Surprisingly, it's no more harsh than it was. I haven't done a spirited mountain run yet though, because I want to get it aligned first., just basic tooling around town so far.
I'm pleased with it.

Looks sweet, the Wife says she can't tell enough, but I'm considering it, I think it looks Perfect the way your wheels fill almost to the fender now, I wonder if it well settle any.

yellogixxer · 09-17-2012, 07:14 PM

They say it should settle after 3-4 days. The pic was taken less than 1 day after install, so maybe. it is definitely noticeable.
My wife didn't notice it either, until I showed her the before-after pics.
I will say I have 15 and 20 mm spacers, but I think it needs more, maybe 20 - 25 or wider tires.

Hi all I just got the chance to start on this, like most said the passenger is pita
But can someone help me where the 17m use. How do you get the bolt mount back
On. I can't seem to get back In straight

bdub561 · 09-22-2012, 10:56 PM

Im doing this install right now. I have the front struts off and spring compressors on one. The top hat bolt is just spinning and not coming off? I can feel inside the shock the whole bar spinning when im trying to loosen it with a ratchet. I have no air tools and ive gotten through everything else fine without them. Any suggestions?

*Edit: j/k. I figured it out lol. And for anyone doing this, if you dont have air tools for the spring compressors, its well worth $50-$80 to take the front shocks to a shop and have them switch the springs out for you.

Footloose301 · 09-23-2012, 06:08 AM

Yep. I remember that part being a PITA!

bdub561 · 09-23-2012, 11:43 PM

I ended up being able to get one but couldnt get the top hat bolt off the other. Thank you Mr. Tire. $20 bucks well spent. Ill post pics tomorrow/later on today. Great DIY btw. Repped.

chefsung · 10-04-2012, 06:34 PM

great write up but I have a question...
What did you guys do to remove the 17mm lower control arm bolt?
MY GWAD.. tried impact gun tried just about everything...
driver side I managed to kick it loose but passenger side.. whole different story

chefsung · 10-04-2012, 06:40 PM

looks like im not the only one!!!lol
godzilla... damn you

bdub561 · 10-04-2012, 07:44 PM

Lmao @ Godzilla

1/2 drive and a breaker bar served me well.

speedfreek · 10-04-2012, 09:38 PM

I had the same issue with my passenger side. It took a 900 ft lb air impact wrench to get it off.

Footloose301 · 10-04-2012, 09:59 PM

1/2" with a breaker bar. Fairly easy if you're a man.

chefsung · 10-05-2012, 09:01 PM

Yes. Breaker bar is the answer.

got my swift installed !!
