The X5 is shaking on the high way during rain
 

i was driving to Indianapolis today and it is raining here, so when i hit about 60 mph the car starts to shake badly, every body can feel it, im using 22 and at first it really scare me so i pull over and checked the wheels and stuff but there is nothing wrong, it never do this when its not raining. Any idea guys?

Sounds like more than just throwing a weight. ? bent wheel?:dunno:

Warped rotors. They probably got wet when the rotors were hot.

Does your post say you have 22" wheels? If so, you probably have a lip in which case water is getting caught in the rim and throwing the balance off causing the vibration/shaking. It happens to me with my 996tt, happened on my S4 and I have read many many posts of it happening to aftermarket rims with lips. It is like having snow stuck in the rim and it vibrates/shakes like hell. The price you pay to pimp!!:nanana:

rotated/balanced your wheels lately?

Last time this happend my grandaughter was driving with the handbrake on.
I KNOW you wouldn't do that. Right???

doesn't the car warn your with sound when u left the handbrake on?
