I was just wondering about the company Dinan. I heard terrible things about this company across europe and asia (espeically the BMW's engineers), most of us never even heard of Dinan. Why would you put your M3 to a small, terrible R&D and low resources company to modifly your car. Have you guys heard of company called AC Schitzer or BMW M performance? I am not trying to be rude or anything. I just don't understand why people choose a company with lack of engineering skill for their 'baby'. It just like people choose Renntech instead of AMG, which AMG is thousand times bigger, more resourses, better engineering than Renntech, but people still choose Renntech.....Why?? Aren't you guys worry?? or you guys just don't give a shit as long as there is power.
