RE: E30 highway vibrations
that is what i was suspecting... my 94 e36 has the original sports
suspension and i have brand new tires which balanced to zero... yet i get
a little vibration at 45 but not at 90.... normally, if it is a balancing
problem the vibration will repeat at double the speed.... (as they fall in
the same frequency range....)
my question is, since i am here..... i already noticed my tires getting
worn on the inside (all around, worse in the back) i have 17,235,40
my car came originally equiped with 15,225,50
would i be able to correct this camber problem with alignment alone? i
understand my car probably handles a little better with the camber as is..
but heck i paid 750 for those dunlops 9000
any input would be great... thanks

Nobody has brought up the possibility of worn suspension
bushings. These can cause vibrations too. Have 'em checked!
