an excellent diffuser made of abs plastic for completing zhp or mtech 2. not suitable for m3, but it has the look and style of m3 csl. be careful, you will need to do a dual exhaust like the m3. depending on the bodywork, sedan or coupe (cabriolet) will also need to cut off the lower bumper reinforcement a little. write to me if you have any questions. Sincerely!
