Hey, so I've never really been active on the forums but a few of you know me on facebook. I noticed a lot of excitement towards the introduction of Powertrix coilovers, so I want to share my experience with you all.
A little background:
"Powertrix was started in 2001 out of a childhood dream. The founder, Charles Park had always wanted to extend the performance envelope of the Nissan 300XZ (aka Z32) as a young man. That dream became a reality when Charles decided to leave the corporate world and devote full time to his true passion.
At Powertrix, we research and develop every performance product for your Nissan 300ZX. Through research and development, with many components designed and fabricated to our specifications. We spend numerous hours devoted to development time, researching, and developing a product before we let it lose for testing on the track, road course, and street.All Powertrix products are tested on the track, road course, and street before we give it our approval. We can lay claim to the fact every Powertrix component ever sold has been thoroughly tested and meets our high standard or performance and reliability. If we won't put it our Nissan, we won't put it on yours."''
How I came by these coilovers:
I've mentioned my request for coilovers to Charles from Powertrix (who runs my local Z club) for some time now, and during the last group buy, he was able to manufacture coilovers to the specs of my car. I had Road Track 9k 7k coilovers made for my Z31. The reason I went with these coilovers was due to being familiar with them as I've ridden in many Z32s, and even a G37 equipped with these. They ride better than stock on these cars having a comfortable ride, and yet seem to outperform any other suspension setups I've experienced.
So I received my coilovers and went straight into the installation, and Charles was able to do the welding of my front coilovers. They were basically a bolt-on affair.
The Powertrix Z31 coilovers have 15-way adjustable damping, adjustable ride height ranging from near stock, to just about scraping the ground, a front inverted monotube design, and front upper camber plates. This coilover design has the essentials for a proper Z31 setup.
Sorry about the cell phone pictures by the way!
I immediately noticed that these are quality pieces, and spent a while staring them down, looking for any imperfection, these things came to me spotless.

I had my front tubes welded by Powertrix, and received very clean welds!

The installation was a direct bolt in, and I mated the front coilovers with ASCO bumpsteer spacers. The whole ordeal was quick and easy, even being the first time I've really taken apart suspension. [archived image: biggrin.png]
Here's the end result, and I had a good amount of room to go lower!

I've driven these things for around a month now, and the handling is superb. It's basically like a completely different car and grips like crazy. My ride quality is amazing too considering that the Z32 is recommended to use 8k 6k, and I'm running 9k 7k on a car that's significantly lighter. The damping has a wide range of adjust-ability so I had plenty of room to adjust it for a proper street setup. The car is planted and smooth, tight over bumps, and solid through corners. I'm not in any position to compare these to Stance since I've never ridden in another Z31 on coilovers, however comparing these to other types of cars on coilovers, Powertrix has had the best handling/ride quality.

Wantttttt.
G-E: (2013-02-03 08:56:53)
Because most people buy without really understanding what they need or how to dial them in I bet
DeleriousZ: (2013-02-04 02:47:23)
With lots of room to go lower hey? Hmmmm lol
G-E: (2013-02-04 04:14:30)
It's not low until the tires come off the ground? hehe
Black 89Turbo: (2013-02-04 05:07:15)
Whats the price? Looked on the website and didnt see anything.

They look nice, but Im more than happy with my stance setup.
88Turbozx: (2013-02-04 06:42:25)
Well for the rear's I'm deleting the top seat and using a spacer for a quarter-half an inch lower, and I already lowered the rear about an inch from what it's at in these pictures, and have around half an inch of adjustment left. The front when I was at the lip of my rims on the fender and the pinch weld on the top of my tire, I had around 2 inches of adjustment left if I removed the adjustment tube. Here is the real thing though, WHY WOULD YOU WANT TO GO THAT LOW?
DeleriousZ: (2013-02-04 15:41:38)
Must tuck wheel on 18's.

mooooooooaaaaaarrrrrrrrr low
88Turbozx: (2013-02-05 07:33:16)
Oh, and right now my catalytic converter's heat shield is an inch off the ground [archived image: tongue.png] I've gotten stuck a few times today entering parking lots, etc.
michaelp: (2013-02-05 13:56:49)
My 87 got stuck on my driveway with STs… -.-
G-E: (2013-02-06 20:34:55)
I thought that's what horsepowers were for, getting unstuck :P

That's why you need to live in a non-Communist state that lets you do what you please to your car's exhaust.

Do you just email them or call asking for coilovers for a z31? Thanks. [archived image: rolleyes.png]

ilovemy86: (2013-02-23 05:47:47)
is there going to be another group buy after that one?? I wont have the money yet!!:/
frostvectron: (2013-02-23 06:08:42)
88Turbozx: (2013-02-26 00:41:14)
You can also wait for the next group buy I'm pretty sure. I think there's usually 2 per year.
Showaski39: (2013-04-14 15:57:25)
Looks like Powertrix's website is down
frostvectron: (2013-04-15 04:12:57)
worked for me?
Showaski39: (2013-04-15 22:51:36)
Ah, it's working now - their site was down yesterday. Kept saying account suspended. I guess they just paid their web hosting bill heh
Orbital: (2013-04-21 04:19:56)
I noticed that too when I checked a couple of days ago. Could be that they forgot to update the site or the sale is still going on which would be good for me. I figured the price for Bilsteins + King Springs and the Powertrix price is about the same. Curious also if anyone has received theirs and what they think about them.
frostvectron: (2013-05-31 01:16:50)
In the 1st pic, what are those things on the left of the coilovers?
G-E: (2013-05-31 01:43:59)
They are inverted so the adjuster knobs are on the bottom, in a place you couldn't reach, they are extensions to bring them outside the sleeve
frostvectron: (2013-05-31 02:30:40)
You mean the hose thing with the green knob at the end?
I was referring to the two rod things (unless that is what you're talking about… in which case I don't think I received them?).
liladair: (2013-05-31 02:39:32)
Those 2 rods look like a set of inner and outer tie rods to me, or sway bar end links
G-E: (2013-05-31 03:39:16)
Those are likely z33 inner and s-chassis outer tie rods
88Turbozx: (2013-06-17 07:59:49)
Lol those are S14 outers mated to Z33 inners, they just were in the picture because this was my "suspension collection" at the time. They work well with the slip-on angle spacers and now I have an amazing turning radius and MOAR ANGLE Y0.

is there someone who drives his Z on the lowest position of your coilover?
I'm looking for a set.
Is there someone who has a gaz coilover? some reviews?
Dunkine: (2017-10-09 18:58:28)
Here's an old build thread with GAZ custom made coil overs on a Kouki 300zx. I checked GAZ's catalog and they don't have any Nissans listed even though it has Nissan Page 11 in the contents… I would love to get some stance or powertrix coil overs, just don't have the $1200-1600 laying around right now, too much other stuff to buy. I'd probably buy another Z if I had a spare 2k laying around [archived image: wink.png]

dark-divx: (2017-10-10 07:20:03)
gaz has them, but there are not in the folder. Here I contacted someone and he can offer me a gaz coilover for 750 euro and the welding service is included.
But first i need to now how much i want to lower my car because it is possible to change the options. Because it is custom. I can order shorter struts and springs if I want.

But now I want to now how much I can lower a Z31.
dark-divx: (2017-10-15 13:04:26)
is it not possible to go lower? if you see the powertrixx coilovers.
