Hello from Riga! Sorry for English, but can someone find a photo of original M Technik II signs to prove the kit is authentic. There should be some letters and digits on the back side of each(?) part - for example, Frontspoiler , Heckspoiler , 7 digit part nr., some KBA &numbers und Hersteller: - i guess Pfeba. and small BMW sign. Thanks in advance, Juris
