Anyone know the resonant frequency of a 99 Impreza? It's a base car, not that that should make any difference. I'm asking because frequencies between 4.5 and 5.0 Hz exacerbate disk problems, and my girlfriend's back is messed up.
Thanks in advance!

Before we all make jokes... every chassis is tuned to a certain frequency, so it's not that silly, but I thought the tuning was done so that the front / rear (or was it subframe ?) would effectively cancel each other out, preventing massive vibration etc ?

Great joke though 
I should probably just ask at what speed does the chassis shake when you have really badly blanced wheels. The rest of the math I can handle from there (geek alert!).
And I just learned today the the human lower back has a resonant frequency of 4.5 to 5 Hz. Your head has one too. I know you were all dying to know. . .
