Challenge E92/93 M3 carbon fiber style door panels
During the construction of INDís Blue Max project car, we had the pleasure of installing Ericssonís carbon fiber front door panels. It was a treat just to see this extremely rare part in person, as there are less than a handful of sets worldwide! Unfortunately, the panels were quite difficult to install, and took over 30 hours to install with a perfect factory fit and finish! There were no provisions for mounting, no precut tabs or holes to transfer the OE trim pieces. Overall it was a very involved installation procedure that could have been fixed with some simple modifications to the design.
Fortunately, Challenge Engineering was already working on a solution. The Challenge door panels combine unique character lines based on the OE BMW door panels. Challenge was able to communicate directly with INDís technician to learn from our experience, and used this knowledge to create a better, easier to work with door panel.
The Challenge Engineering door panels feature complete mounting tabs, marked reliefs that allow for easy transfer of all factory hardware, and a factory-like fit and finish. These panels weigh in at 3.5lbs, which is half of the weight of the factory BMW door panels!
