Florida-based tuner PSI unveils a new tuning project based on the BMW Z4 Roadster. The tuned up roadster was painted in the polarizing and sun loving Atacama Yellow.

Besides that retina-scorching paint, and the obvious modifications present, the full BMW Individual Piano Black interior really ices the cake like a boss. This combination is not exactly commonplace and turns this Z4 into a quite unique roadster.

The owner decided to his car to the next level so before long, the mod list had grown to significant proportions, and the end result is what you see before you. Very few aspects of this platform were left untouched. From the perfect stance, to the intricate exterior and interior details, this has to be one of the most complete Z89s we’ve ever laid eyes on.


The first thing that stands out is the venerable Volk Racing TE37 wheels in Formula Silver, wrapped in Falken 454 tires and sitting in front of a BMW M Performance Brembo Big Brake Kit, ensuring rapid deceleration when deployed. A set of 12mm spacers all around help push the wheels flush, and H&R springs provide that streetable ride height. A myriad of OEM BMW parts help round out the exterior, including the M-Sport front and rear bumpers, front black grilles, and shorty antenna.

Adding the the significant road presence is another premium part from Japan, the 3D Design carbon fiber front spoiler, which matches the Tekarbon carbon fiber mirror covers. Adding some heft to the underwhelming factory exhaust note is an Eisenmann full downpipe-back exhaust, and combined with the AFE cold air intake, Evolution Racewerks intercooler and Cobb Tuning ECU reflash, it unleashes some serious power to accompany the noise.


Inside, more BMW parts were installed, including the M-Sport door sills, steering wheel, and aluminum foot rest to go with the AC Schnitzer aluminum pedals. When combined with the BMW M Circuit Leather/Alcantara black sport seats and suede dash with yellow stitching, the effect is visually profound. Even the roll bar features a carbon fiber cover from Tekarbon.


There may be more race-derived versions of the E89 Z4, but this example retains what we consider to be the ideal balance of everyday usability and track capabilities, with very tasteful Japanese styling and a healthy dose of OEM+ parts from BMW.
