[QUOTE=Z1 Performance;9184711]they have a mild drop

That's good info- I have 84,000 miles on the Z. I live in the DC, so the roads aren't awful; potholes are rare but there are several dips in the pavement. Right now I've got something going on with the wheel
bearings or compression bushings, or something in that
region. Basically, the car shakes
after 60 mph. I read some older
posts on here that suggested
those things may be the cause.
Because, apparently these
bushings/ bearings go bad
gradually. So I'm trying to take
this into consideration when
upgrading the suspension. Also, the tires I've ordered are Michelin Primacy all around.
