[s-cars] Noisy Stromung in the rain

[Steve Marinello]

I had a similar thing happen on the urq.  My evaluation was that the cold
water hitting the low hanging exhaust caused contraction that reduced
clearance to a point on the underside of the body.  The EM and front part of
the exhaust stays hot, so that shifts the induced stress angles from when
everything is cool or hot.  I found where the closest contact point would
be, based on that assumption, and tweaked the exhaust a little there;
problem solved.

Now, that being said, I've also had similar occurences on two occassions
when driving over melted slush and sand grit in Colorado.  That easily could
have been both the cold and some grit getting jammed into the small
clearance space.
