F82 M4 – Bolt In Roll Bar Development

From the beginning, we knew our “Sakhir Inferno” M4 was going to have plenty of exposure to track events, and in keeping with the motorsport theme we began planning a custom roll bar for added rigidity and rollover protection. One of our many stipulations was that the bar had to be completely bolt-in for easy installation and removal. With the launch of the DTM Safety Car M4 earlier this year, our goal was solidified, and shortly after our M4 arrived we set to work.

Using the M4 Safety Car as a reference, we brought in an expert fabricator to create our own version of the competition roll bar. When tackling a project like this, it helps to have experience on your side, and this person has plenty. The fabricator we contacted has a history of building Grand Am, American Le Mans Series, and Rolex Sports Car Series roll cages with other custom fabrication work.

With the SEMA Show rapidly approaching, our M4 is undergoing significant modification, and this race-spec roll bar will be a major component of this project. Stay tuned for more photos and progress!

KW H.A.S. Sleeve Kit for BMW F80 M3 + F82 M4

PSI is proud to begin offering the new KW Suspension Height Adjustable Spring (H.A.S.) System for the BMW F80 M3 and F82 M4! Those of you who have been looking for a solution that allows you to adjust your ride height while retaining the OEM EDC capability – your time is now.

KW Suspension is a household name today in the world of street and competition suspension systems, and rightly so. Their reputation and quality speaks for itself. The new H.A.S. for the M3 and M4 utilizes front and rear KW progressive-rate springs with threaded height adjusters. Your existing OEM shock absorbers remain in place, allowing all electronic controls to continue unchanged.

The true beauty of this setup, in our view, is the infinite height adjustment afforded by the threaded sleeves, allowing you to pursue that perfect stance while allowing the EDC to function uninhibited. We here at PSI fully support KW products for the M3/M4, as befitting a world-class sports car platform.

Weight: approx. 40 pounds.

NEW RELEASE: Vorsteiner BMW F8x M3 + M4 Carbon Fiber Front Spoiler!

PSI is pleased to offer the new line of carbon fiber aerodynamics by Vorsteiner! As with all Vorsteiner products, each piece is produced with an eye for innovation and style, as well as true aerodynamic aid. Every part is modeled using a 3D scanner for exact accuracy and perfect fit. Pre-production sections are wind tested and formed for minimum drag coefficient and maximum effective downforce, reducing lift at the front axle. Every individual segment is specifically formed to both enhance appearance and yet seamlessly mesh into the existing bodywork.

The Vorsteiner autoclaved pre-preg carbon fiber structure gives their parts superior stiffness, aerospace strength & durability compared to traditional hand laid carbon fiber composites. Vorsteiner’s trademark vacuum forming process enables superior rigidity and durability, while special UV-inhibiting clear lacquer coating protects the parts and keeps them looking fresh for the life of the car.

Vorsteiner’s continued drive to explore new horizons and make advances within the realm of technology and manufacturing will ensure their market leadership for years to come.

The Vorsteiner F8x M3 + M4 Carbon Fiber Program includes the following:

  • Carbon Fiber Front Spoiler
  • Carbon Fiber Rear Diffusor
  • Carbon Fiber F80 M3 Trunk Lip Spoiler (also fits F30 3-Series)
  • Carbon Fiber F82 M4 Full Trunk Lid (no spoiler)

We now taking orders for the entire kit! Please contact us today to reserve yours.

Full Yellow Jacket


Every so often, as we trek through life, we really score big. Perhaps not in the traditional sense of a bank heist or lottery win, but in an area that truly matters to us. Looking back, we wonder how we came to be so fortunate. While sometimes owning a car can be mundane or even frustrating, occasionally there is such a highlight that everything else pales in comparison.

By way of illustration, have a look at this rare and beautiful Acatama Yellow BMW Z4. 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, so when our client came across this one-owner car for sale, he knew his time had come, and he immediately closed the deal.

Many owners of such a unique ride would then immediately sequester it from any possible harm, and insist on leaving everything stock, possibly with resale value in mind. And then, of course, there are those that simply want to enjoy their car, no matter its relative rarity in the automotive world. To people like that, we tip our hat. Machines like this are meant to be enjoyed, not kept in a bubble. After all, why are we car enthusiasts?

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, and we were thrilled and honored to see this dream become a reality. 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 to 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. On the listening end, contributing 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. Under the rising Florida sun, this gorgeous Z4 roams the streets in a full yellow jacket, catching envious stares and wistful glances alike. Blink, and it vanishes around the corner, leaving behind only inspiration.

Enjoy the photos!
