I ordered sport struts online for my 2005 g35 coupe and am hoping they will fit it. I have stock non sport struts on right now. Will there be any issues with installing these or are they the same, just with upgraded coils?

 

EDIT: There are different Nissan part numbers for sport suspension springs/struts. Editing this post to reflect this information and preserving the original comment (that was wrong) inside this spoiler.

 

They are the struts for the G35 coupes that had the sport package option. In the sport package you get different struts and shocks which are slightly stiffer from what I have read. I want to put them on my car that did not come with the sport package.

 

I just verified there are different Nissan part numbers for the sport suspension struts and springs, apparently they ARE different, including the struts.

 

Which raises the question for me if I were to do a slight drop, since I have a sport suspension: what would be the implications of the 350Z spring approach? Would that end up with worse handling?

 

Do you think they would still fit on a car that came without them?

 

I have a 2006 6MT coupe which had the sport suspension factory installed. I initially kept the same struts and put the 350Z revised springs on it with zero issue. When those struts wore out I replaced them with KYB Excel-G which is a good OEM replacement.

Yep, they'll fit, the difference would be the internal damping not the physical dimensions for springs/mounts.

 

Why did you get oem struts? Why not go with something better if you plan to drop it? I would have gone with at least tokico blues.

 

Just make sure you get the right 350z springs for your shocks. There are two different versions, unrevised and revised; they have different spring rates.

I put the unrevised springs on my 05 non sport. You will also want to do the spring mount mod for the rear. I recommend cutting off 1/2in to level out the car otherwise you won't see much of a drop in the rear.

 

I don't think the Tokico blue is produced for the G35 anymore which is a shame.

 

It's not made period anymore.

 

I recently researched using factory Tokico part codes for shocks and struts for sedan and coupe with and without sport packages. All had different part numbers, all had slightly different compressed and uncompressed rod lengths.I could not find information on the dampening rate differences, but I would guess there might be a slight difference as well.

 

Kelman, that research sounds very useful. What aftermarket shocks come closest to the red Tokico sport shocks? I'm looking for what to get for my rev-up sport G35 sedan.

I assume based on the compatibility in springs between 350Zs, G35 coupes, and G35 sedans that any shock for the 350Z would fit the 2WD sedan.

 

Not sure about an aftermarket for the sport shocks. I have a sedan and just ended up replacing my shocks and struts with a base OE equivalent (Monroe and FCS, cheap).

Yes, the suspension bits for a similar year 350z will fit and interchange on a rwd coupe or sedan. But I would not mix different types of shocks and struts and different types of springs. Meaning don't put 350z springs on a sedan shock/strut and don't mix setups between front and rear. A shorter Z spring may have a higher spring constant and if you pair it with a softer, longer travel shock from a sedan that has decreased dampening, things could get bouncy or load strange. Make sense?

There is a good writeup sticky in the suspension section discussing spring rates, dimensions, and shock options.

 

That definitely makes sense, yeah. Since that amazing thread was compiled, it seems that many of the springs and shocks mentioned have slowly disappeared. Tokico, fo' instance, doesn't make a single shock, so an OE replacement means you're down to choosing between the same boring KYB's or Monroes that also go on Altimas. I've never even heard of FCS.

My goal is to replace the existing red OEM sport shocks (I'm just assuming they were manufactured by Tokico) and springs with their closest equivalents--that don't drop the car enough to cause problems on America's deteriorating roads. Infiniti parts websites don't even make it obvious whether you can still get the higher spring rate sport springs--I guess I'll have to email a parts department and see what's available.
