Our project Z4M is a dual purpose car: it's both a daily driver and a weekend warrior. Lowered on a set of AST 4200 Monotube Coilovers, which are comprised of the AST struts, Swift springs and Vorshlag camber plates, this E86 is stiff enough for the track but usable for the streets. For even better handling, we installed some lightweight M3 fitment (18"x9.5" +25mm front, 18"x10.5" +22mm rear) Work Emotion 11R-FT Wheels wrapped with Falken Azenis RT-615K tires (265/35/18 front, 275/35/18 rear). To keep the driver from sliding around during hard cornering, the stock seats have been replaced with a pair of cloth Recaro Pole Position seats mounted on Macht Schnell Competition Liteweight Floor Mounts. With the handling of the car dialed in it was finally time to add some power; stay tuned to see this car get a dose of forced induction!
