HELP, NEED ADVICE!!!

[golf on 20s]

hi guys i need your expert advice again, ive just put a set of porsche wheels on my mk1 cab using hub adaptors,  the car looks the dogs but the handling and steering seemed to be a bit soggy and unresponsive and not very good to drive, however i started the car today and i noticed a broken engine mount at the rear of the engine, could this have  anything to do with thee handling?

Replace the engine mount first then try it. If it still feels strange get the camber and tracking checked, play around with the tyre pressures to see if it helps. I have driven cars with big wheels and they do feel different.
