We need someone to make aftermarket polyurathane ones! SPL is too much for DD cars.

In progress :) My Nismo is the 3rd test car!
They are urethane bushings with an aluminum sleeve.

I don't think the Tein springs would have much effect on the bushing. IMO, high HP levels, hard launches and shifts would hurt the bushing far more than anything else. I've had a few friends with 350Z's break theirs and a few friends down here in FL do the same with their 370Z's. It seems to be common with both cars.

I contacted SPL about this. With some work/swearing the 350Z SPL bushings can be adapted to the 370Z/G37. They also mentioned that they will be releasing a set that fits the 370Z/G37 soon.

With that said, the SPL bushings are LOUD. Especially if you have a set of 4.08 gears, and/or a Nismo LSD. The 4.08 gears might whine a bit more than the stock gears, and this is magnified by the solid bushings. The Nismo LSD is a bit harsh to begin with, makes lots of noise when making slow tight turns (read: parking lot). This is also magnified by the solid diff bushings.

I would NOT recommend these for a daily driven car. But constantly breaking a stock bushing would also be irritating. Maybe some day someone can source/manufacture a solid rubber bushing.

two things which i have not done with this car. ive been babying it much more than abusing it..... :\

The bushings are not replaceable with Nissan parts. Dealership sells as an assembly, no bushing alone.

I wish I knew about the urethane bushings a few weeks ago but oh well.

The stock bushing is a major PITA to remove. Installing a replacement bushing is PITA as well. Just got my Z back with SPL aluminum bushings, a review thread soon to follow.

I don't know if I should do this or wait for the whiteline bushings now. I think metal bushings will be a little too much for a DD

i would wait. mine isn't a daily driver so different story for me. the extra rubber padding helped though.

I'll have to do this before my next alignment

Whiteline ones should be for sale in the US end of November...
