Owned this car for 4 years and have done extensive modifications in that time as well as have meticulously taken care of the car. I bought the car stage 2+ with the meth kit already, and have since added a NVM 520r hybrid turbo, m performance LSD, M4 LCA + TS, powerflex subframe inserts (black) and updated the brakes with perforated discs, ds2500 pads, motul 660 fluid, and braided lines. The car as it sits makes 540bhp and 750nm but has a switchable map to not run meth, I did this for the purpose of track and not worrying about running out of meth. This map makes 510bhp. It took a while to find this car with this spec and comes from factory highly specced with pro nav, HK audio, adaptive suspension, and heated seats.
