I've heard this is a common one for G owners. After my last oil change, Infiniti let me know my rear subframe bushings are broken and they wanted to charge me $1400 to do it. After a little bit or searching around I've found some kits I could buy for cheaper, though I'm not sure sure if I've found the correct ones.

If both work, I think I would prefer the solid ones for durability. This is for a 2011 g37x coupe. Thank you for taking the time to read this!

 

It's more the labor than cost of the bushing. Just remember if you do poly bushing it will make ride firmer it doesn't bother me but you'll feel more vibrations vs using rubber

 

I am looking for a firmer ride all around (I also just got a set of Hotchkis sways). How bad are the vibrations from the solid aluminum set?

 

After my research I decided on Whiteline. I have yet to install them though. I would advise against solid ones from the negatives I read about them.

 

Could you please post what you have found ( or links to them) about reviews for the solid ones? I'm very keen to know what others have experienced. Thank you!

 

It's on the forums. You know how many things I have researched in the past 6 years on here, lol? I can't recall the specific ones. Spend a bit of time on here and check out the370z.com. They will have more input about solid ones. IMO, if you don't track the car, they are not necessary and are overkill.
