NEED HELP: ksport coilover install
 

Ok so im pretty sure this is correct but i want to be 100% sure. For the rear coilovers do you remove the spring from the shock and install it like the OEM setup? The springs came on the shocks. never delt with this suspension setup i come from the scion world :shakes head:

Need help ASAP cuz im working on it right now and this is the only thing holding me back thank you.

A pic might help. But the rear shocks and springs are separate. Just replace the oem with your aftermarket ones.

Sorry about that, pic:

check ur email.

let me know how it goes at ur shop.

So guys,

are these suited for the rears? Is the top mount strong enough?

It looks like those may fit and work. My only concern is that nissan did not design the springs to be under the area where the struts are. I don't know if the z can handle the extra force from the springs.

That's a concern I read when I had the 350z as some people wanted the strut and springs to be combined. Even though nissan tested and designed the z to have the strut and spring separate for better handling.

Honestly, I don't think many coilover companies do as much R&D as nissan.

I know what you mean. I think the idea is to make the rear end tighter. I did a test fit on the front and it fits great, no issues. I should be able to put them in tomorrow if I can get an appointment with nissan the next day to do a wheel alignment and make sure the camber/toe is good to go. I'll also right a thread on fitment, weight (need to buy scale), and install. This will help ppl have confidence in the install when the shock and spring are together. If I cant get an appointment then ill be installing it on thursday and go to nissan on friday.

Thank you everyone that helped.

I would say make sure they sent you the right part number(s). They could have inadvertently sent you the wrong coilover set. I find it surprising that an aftermarket company would design the coilovers with components that are not direct replacements (shocks and springs separate) for the intended car. That's like trying to reinvent the wheel, even after the car manufacturer has done their homework. Good luck with the install.

Install at your own discretion. Take a look at the tower brace and you might see that there are no reinforcements there.

That's right, the front strut has 3 bolts and the strut tower is reinforced. The rear strut is secured only by 2 bolts, and like cab83 says, not reinforced. No way it can sustain the load born by both the strut and springs. I'm sure this would raise some red flags for the mechanic at Nissan too, when he sees this.

So you guys are saying I should get my money back and send them back to the vendor? If so I hope he will let me do that, they were special order.

Verify the right parts were sent for the rear...really doesn't sound right at all.

I'll talk to the vendor and see if I can send them back. If not then i'll call Ksport and ask WTF is up and tell them the stock number to make sure the parts are correct. This is why I didnt even want to remove them from the box in the first place but I did to see if they were even the correct ones. A guy on the forum with HKS hypermax told me that his 350 had the same setup but the brand included a bar to put in place of the OEM springs, he never mentioned any problems. I'm dissapointed, coilovers is such an easy install... :shakes head: and i had to wait 3wks for these to only get made :shakes head::shakes head: lol

Check this bullsh** out. THMotorsports had them listed for the 370z but its for the 350z!!!. I took someones advice and checked out there sight and its not for the 370Z. Yea, im throwing THMotorsports under the bus. I paid $1,100 for specail order, waited 3wks for them to be made, another week to ship to my mom's house, 1.5wks to get to me, and my mom WAISTED $144 dollars to ship them to me here in guam. I want ALL my money back and my mom's!! Pretty sh**ty cuz my mom did that for my birthday, i normally pay for shipping.This may be a little harsh to some, but this is how I feel. I also don't care the 350 and 370z suspension is comparable or not, its not listed so im not keeping them. What a way to start my build.

Ksport USA - Performance Suspension

I'm pretty sure the ones you got are for the 370z. The 350z front shocks looks like a fork, the 370z has the socket design. My explanation is probably confusing. If you want cheaper coilovers you should get bc.

Well, in all fairness, give THMotorsports a chance to make things right. It could have been a simple mistake.

Im just mad cuz i could use the money for 1.5way or 2way and 4.08 finall drive...I'll be calling them tonight. And I dont want cheaper coilovers, thats not the issue. If I was to get new ones, i'd be the hks hypermax 3. Thank you for the help guys ill let you all know what happens.

Never seen the 350 coilovers but im sure i would understand if i had. Like i said above thank you for the help ill post up what happens :shakes head: i taped up the box already.

Another member is selling a set of Tein MonoFlex coilovers. Looks gently used and in good condition from the pics. You may want to consider these. Check out the thread (I am in no way affiliated with the OP, or getting a kick back for the advertisement...though maybe I should. LOL :roflpuke2:):

http://www.the370z.com/parts-sale-pr...ustable-2.html

I have an identical set and I would recommend them. :tup:

Oh, another set you could consider is KW V3...heard good things about those as well.

haha, ok thank you ill check it out. +1 for dj and azn, you guys were helpfull.

Much appreciated...keep us updated. Oh, I was looking at your signature and noticed that you are getting an ARK exhaust. I just read another post about someone else having problems with that...no offence to ARK and I'm not trying to worry you, but check out this thread just for info:
http://www.the370z.com/intake-exhaus...o-what-if.html

LMFAO!! dude, i seen that 2 days ago and was pretty PI***** OFF! lol. It sounds so good but that x pipe sound worries me. It gets to my moms place in 2 days so im trying to see if i could wrap it in thermowrap and if that would work...:shakes head: never had this problem before. either that or just have my mom deni the drop off and return to sender and get the money back. maybe ill get the HKS or the GTM 3" and get the 3"TP's seeing that ill be TT not to far from now...maybe 3-6 months. I got the coilovers for the sole purpose of laying power to the ground for the drag radial setup im going to be working on once i get the 2way and wheels.

here is another one:

Don't know if they are the right parts or not, but not feeling comfortable with the shock and springs combined in the rear myself. If you do return them, get the monoflex mentioned above. I have them and love them.

Thank you for chimming in mike. Im a little cooled off now, wasnt too happy with what i had seen on the ksports site. I wonder if they have EVER done a special order for this item on the 370...or maybe they just did some machining and modified the 350 one to fit the 370. IDK but i want the money back so i can order my differential and 4.08.

hmmm...I see Mike Bonanni's name on a card in the boxed kit. He's a reputable guy.

Maybe it's just the vendor (not ARK) that's the problem for that poor chap in the link I sent you earlier.

Here's another post about ARK:
http://www.the370z.com/intake-exhaus...-type-2-a.html

I stummbled across that one right after i sent you the link. The thing is, alot of ppl get the exhaust hoping it will be tame and if it has any sound refering to "their" deffinition of "rasp" then they hate it... i think ill go through with it and hope for the best. If that sound is true then i hope the wrap will work... :/ it could be the installers or a faulty system. make thousands and one is bound to be the ugly duckling

as for the coilovers, the more i think and look at the setup the more i think it would work fine. the control arm should operated just fine without the spring on it. all it does is hold the wheel in place and the spring is there to rebound for the shock....question is, ytf did nissan assemble it this way. maybe the springs are just too big to fit with the shocks. Im going to call tonight but im starting to understand more and more that this setup would actually work and is a great setup for racing.

My thoughts are correct, you just remove the spring from the control arm and install. I called ksport to verify. He mentioned that they haven't updated their site and that is why the 370z is not listed. I did pm thmotorsports (nick) and appoloize.

For the way they set it up I was also correct (after looking and studying) and it is to make the suspension stronger for track use so like MUST mentioned in a PM to me (....creating a formitable track car....) he was correct. Thursday (your wenesday night/early morning) i'll be doing the install and posting up a review of fitment and feel. To break it in ill only set the dampening to 18 (36way).

Thank you all for the help :)

Nissan did this because it is a more efficient suspension design. A lot of newer cars are doing it now. Mini, BMW and even the new Civic SI.

anyways its not a problem of whether they will work on your car or not. It will work on the car. The problem is that the rear top mount is not reinforced. I dont know about the z but I did the same thing to my AE86 which also has a seperate shock and spring and ripped the top mount of my rear suspension.

It's not worth the risk to me. Also any kind of deformation of the mount will affect the pitch of the shock.

The rear top mounts are supposed to be rubber so i see no reason for concern. That sucks about you AE86

I think he meant where the top of the strut meets the frame of the car is a thin layer of metal. This area may bend or break.

The rear SHOCK mounts are not rubber. A rubber base sits between the upper spring mount and the rear spring.

so did you seperate the spring from the strut and installed them seperately? can you post picture of your rear install?

no it's installed as a coilover unit onto the rear of the vehicle. And yes AZN370Z thats exactly what Im talking about. The frame on the vehicle will be bent from the force of both the springs and the shocks or are put where only the shocks are supposed to be.

that was my concern with this design too.

well i hope not. I think it will be ok, i just cant be hitting any pot holes i guess. In about 6 months this car will no longer be daily driven. THmotorsports said they have never had any issues with this coilover. If I see that there may be an issue, I know alot of ppl that can fabricate me something that can support it.
