I am looking for rear subframe bushes for my turbo because they are worn and make noise.
I would like to install powerflex, i found these références rf57-511 (x2)

Ar prf57-512 (x4)
But this is for 996 turbo, i have asked to powerflex and they cant confirm that it fits to 997.

Anyone knows if it works ?
Or maybe an other brand ?
I have seen some rigid parts but my car is stock and it is only for lowered cars.

Thank you for your help!
