I am a new Porsche owner as of a month ago. I bought a 01 box, black on black.59k miles. I immediately noticed the road noise was bothersome. I chalked it up to bad tires. So, I just put on a new set of RS-903 wheels from Wheel Dynamics in California with Michelin super sports on them and the noise is still there. All be it a little better.
zzz..zzz..zzz..zzz..zzz..zzz..zzz about 35miles an hour up. Like the tires has a rough and smooth side.
Definitely wheel associated. it doesn’t change with gears or clutch. the sound does change a bit steering side to side. I am replacing all four wheel bearings next week and will post the results.
my question is never being in a box before how quiet can I expect the car to be?
what is normal for this car? Anybody ever measure the decibel level in these cars?
I can’t believe what I hear is normal or that Porsche would put anything like that out.
I am not sure what’s normal or abnormal for noise. Any tricks to making these cars smoother and quieter?
Thanks
