I just order as set from
www.getBMWparts.com. Aero side skirts an Aero nose.
I was at a fundraiser Sunday and someone backed into my Z4 and took off. A lady came in and asked who's car - she saw it but the person jus took off and she didn't get the plate.
Well they were going to fix the bumper and re spray it so I figure now's the time to get the Aero stuff.
