2002 q45 rear shock solution

Post by **Wkennedy7518** » Thu Aug 25, 2016 10:48 am

Well after doing some research and talking to a couple of suspension companies who make coil over suspension setups for the 02 Q45 and the 03 M45, I have found a solution for the Rear shocks atleast. I have confirmed that the rear shocks for the 350z and the 03 m45 will fit the 02 q45 without any modification. I bought the rears for a 03 m45 from rockauto for $120 for both shocks and they work like a charm, the car rides awesome. I went with the Monroe 5632 but any shock for those cars will work. I do have pics so if u need proof I can email them to u. I'm still looking for a cheapersolution for the front struts but ones for the m45 will work

What's this? A solution, not a question, comment or complaint. And a first post? I wish what you have was contagious! Welcome to NicoClub.

I think you could upload the photos to a free hosting site and use the url's to embed them into this thread. The pictures would be nice. Do you have part number cross references to share?

Welcome to NICO! Great information!!

Yes- thanks for sharing - this is getting tougher and tougher finding parts - If you find a front end solution let us know. I can also host your pictures on my website.

Dear Wkennedy,

It is very nice to hear that rear suspension for 350z and M45 fits for Q45 2002.
I am having Q45 2003 which needed rear and front shocks especially rear shocks badly.
I approached too many vendors they having very high cost replacement for the same.

I would like to know, the compatibility is just the shock absorbers or the whole Kit for both Left and Right side shocks of 350z with Q45?

Awaiting your esteemed reply.

Wonder if this works for the 98-2001 q45?

Dear Team,
I have purchased KYB shocks for Q45.
I couldn't remove the rear recliner seats to install the same.
Please let me know the removal procedures in pictures.

It would be more beneficial.

Have you laid your hands the Factory Service Manual for your car yet?
Here is the section on rear seat removal: http://www.nicoclub.com/service-manual? ... 003_Q45/se, page 200 -ish.

I'm not really sure about the rest of the suspension but when I talked to a company who makes a coil over setup for the two cars. They in a nutshell said the suspensions where identical, so I could imagine you could interchange other parts too. I was really concentrating on the shocks and struts. Looking at the service manual theydo look very similar if not identical.

I can't post web addresses on here, but if you look in the service manual sections on the site and look for rsu and look for yourself you will see its basically the same

As far as the front struts I think we are stuck with oem. Either for the Q or the M. The M's are cheaper but because of the spindle being attached to them, there is no other option.

How about part numbers and what other parts they equate to?

Some links I meant to post earlier from the m45 side. I like crossing over info since these 2 old platforms are more similar than we realize some times.

The only part#'s I have are for the shocks I purchased. The Monroe 5632 shock which is all I replaced on my q so far from the m45

I just researched my 2005 Q and the 2005 Z, the suspension is the exact same not only the shocks, but all of it.. you can compare on Nissan estore and Infiniti estore. They have same part numbers for control arms, platform, all of it.. compare the photos of the schematics. Crazy they would adopt the Z's rear suspension.. but that makes sense because the focus on the F50 was performance; and at the time Nissan was pinching pennies in 1997-1999 when the F50 design was patented and Nissan began there Revival Plan with Renault.

I'm not surprised it's pretty much the same for the Q and the M I think the only difference is the length of the shocks and the damping which is a minimal difference. I need ball joints too so you know I'm going to more than likely not be getting the ones for the q

Post by **O5Q45** » Wed Nov 30, 2016 8:47 am

Do you guys think I could use Z parts since they are exactly the same? You mentioned the damping and length may be different but wouldn't there be at least one digit in the part number different? If there is a length or damping difference would thus cause my Q to sag and squat.. looks like the front suspension is identical too! Will someone else go check out the schematics on Nissan estore and then Infiniti estore. It's hard to believe.. Did R&D just run out of money? Front and rear adoption from the Z would create a performance sedan.. was this only done on the F50s?

Looking at the service manual diagrams, Yes the Z350, M45 and Q45 Rear Suspension is the same as far as I can tell when it comes to the shocks and springs maybe even the stabilizer links and a few other parts for the rear only. The fronts are a different story it just looks like they are different from the diagrams and even looking at pics online it's just not the same to me, now with the 350z but I do see some consistency between the q45 and the m45 enough to say yes its the same, which confirms what the suspension companies I spoke with already told me. As far as the damping and length you are talking very minimal differences which wouldn't affect the sag. I believe the rear springs handle that part which are separate from the shocks. I have aftermarket M45 shocks and there are no issues and the car doesn't sag at all. To answer the first question, I would say you could use some parts from the rear of the 350Z and almost any part from a M45 but if you didn't want to pay the premium for the q45 parts your only choice is the M45 for the front

I'm looking for a set of coil overs now for an '02 F50. I'm hoping to have to do the least modifications to get the coil overs installed.

After some research, I've found that many coil over sets can work. They just require cutting and welding of the stock spindle to the coil over.

There is a company (in California) on eBay offering a set of BC Racing coil overs w/ the F50 spindle already welded on. Here is a link http://m.ebay.com/itm/For-02-06-Infinit ... Ciid%253A1

What do you all think of this set. Your opinions are appreciated and valued.

All the best,

Pretty nice set up and a nice price. from the pics it looks like there is some work that needs to done to the fronts. The oem ones have more to them than those but taking them to a good shop they will know what has to be done to them. If you look at the link the fronts are like no other car I've seen q45-f50-ksport-coilover-install-t584835.html. The rears look like plug and play so no worries there. I'm just speaking on the experience of changing mine myself. I would say before you buy take the info you have to the a shop and see what all is required before you pull the trigger because you may be in for more than you think. just my 2cents

Apologies for just getting around to replying to this thread. I've been having a GREAT TIME adjusting the BC Racing coilovers I've put on my F50! With the OEM active suspension, I'd never have enough confidence to push the car on the freeway past 100 MPH. Now, with the coilovers, the car feels like my brother's Z06 (I may be exaggerating, but only a wee bit LOL).

As far as installation, yes the OEM struts do have a few tabs made on them, to hold the brake line. The BC Racing coilover does not have that. They do include four ring clips that you use to secure the brake lines. I wound up just using zip ties for now. Everything else was a breeze. Out with the struts and in with the coilovers.

That KSport coilover job linked above looks like a thorough job. However, the BC Racing coilovers come ASSEMBLED and ready to go. I highly suggest them. I didn't have time to go thru all of that fabrication.

All the best,

Ok so if the Monroe for the y34 03 m45 will work for the f50 02 q45 then the kyb 344492 for the g35x will work also as this is what I have installed in my y34 m45 with no issues whatsoever in 3yrs that I've had them.

I would double check. If I'm not mistaken, the BC Racing Coilovers come with springs setup for the exact weight of the F50 Q45. I'm not sure all of the cars you mention will have the same weight [Q45 x M45 x G35x]

Mixing and matching the coilovers from these different cars may not work well, as you may need a spring to handle a specific weight, properly.

All the best,

Post by **JOHNQ** » Fri Apr 20, 2018 7:12 pm

Kyb 344492 is not a coilover. It is just a plain old shock absorber made to work with the factory springs.

What year 350z works? I just purchased an 02 Q45 and am starting to regret it because the rear suspension is bad and I can not find a cheaper substitute.
