Hello,
I have a 2011 G37s coupe. I wanna replace bushings with polyurethane. Does anyone know of a company that sells a kit? I’ve looked at Z1, white line, stillen, and summit racing. No Bueno.

 

Differential Bushings? https://www.z1motorsports.com/z1-pro...t-p-10356.html

 

May help to state what your issue is with the ones you named

 

I just want to tighten things up
. Polyurethane bushings are a great (in my opinion) cheap upgrade for what you get. For example, I once owned a 1985 Monte Carlo. It drove and handled like you would expect. a large catamaran. lol. I put sway bars and replaced all bushings with polyurethane and the car drove like a honda. I was amazed. From then on I try to replace these bushings on all my cars. My Dodge 2500 Cummins Diesel has summit racing poly bushings. lol

 

What I mean is why do you not like the ones you listed?

 

I think by "no bueno" he's saying he can't find an all encompassing kit. And I believe that's correct. I also don't think it matters. Just buy the bushings you want targeted for the areas you want them for. It's not rocket science.

 

Energy suspension bushings are good...were good. IDK if they make a kit for the G but Ihave used them befor and that would be my choice if you can find them. If they don't make a kit for the G, maybe you could use one for the Z...I think the suspension setup is pretty much the same. Someone please correct me on that one if I am wrong

 

Let me know what you end up doing, my front end feels like a sponge, wanders on freeway. Took it in for an alignment but that didn't help much. They checked control arm bushings and said existing ones are good, only have 28k miles on them, OEM. Compared to my Honda and 435i (I used to have) steering feels rather imprecise.

 

I agree 1000%, I have a G37S Coupe and I have looked for months with No luck, Problem is they have Poly bushing sets for almost everything on the planet except G37! Sure you can buy one Part here and another there and z1 has a few at top dollar but a whole kit, NO!
I can find one for a 1998 GS400 Lexus but not for my 2011 Infiniti G37S Coupe 6MT WHY?
Any Help Would be Greatly Appreciated.

Thanks Everyone

 

They're out there. Not a a kit but individual target areas.

There's polyurethane substitutions for ALL busings on the entire car FYI.
