M3 wind effects

[speedmaster]

I'm in love with my M3 most because it's kart type turn attacks.... but I've noticed that it is very sensitive to lateral winds and it shows by waving the body lateraly and also when passing a truck when you reach the air mass again... It is the first time I have a low profile tire equipped auto so is it the tires? Or is it the electical electric pump (maybe a lag as I know it hybernates while not being that used) or is the aero of the car that is susceptible to lateral winds?

Other than that: grooves in the front left rotor with 200 miles although I can see them I can't feel it with my fingertips (maybe because it is not that used yet).

I love the car... great ride! Hope the problems can be fixed shortly. I think this is the price to pay for a version 1.0... lets see the service packs...
