noticed the rear uses the original bumper, but different diffuser. another problem is, the quad exhaust are placed center, normal 535s are by the sides. guess you will have to get the exhaust system from prior design too. but yeah, love it. better than msport for sure. i think the front resembles more to current current M3/ericsson kit. Man love those super concave rims.. so sexy. shit... i think f10 it is...
