Contrary to popular belief, Werks1 carbon fiber parts are not only made to be used as extremely pretty cosmetic add-ons.  Although it's definitely hard to find a flaw in the beautiful hand-crafted carbon fiber weave of any Werks1 part, what most people don't realize is that every single piece is engineered and designed with appearance as a secondary requirement, and function as the primary.  Looking at the Werks1 997.1 carbon fiber rear diffuser, it's easy to see how the perfect carbon fiber weave, finished in stunning glossy clearcoat, can make it easy to forget that it's actually a very functional aerodynamic part.

The Werks1 diffuser was designed using the most state of the art engineering and computer modeling techniques available today.  Using these processes, a functional prototype was created and wind tunnel tested in order to verify the effectiveness of the part.  During testing, it was proven that a stock 997.1 (with wing raised) produced over 40lbs of lift at the rear axel, at 175mph.  With the rear wing raised and the new Werks1 diffuser installed, that number was completely eliminated, and the test vehicle not only showed no signs of lift, but it now produced 14 lbs of usable downforce, again at the rear axle.  When measured at both the front and rear axles, the stock 997.1 showed nearly 110 lbs of total lift.  Once the Werks1 diffuser was added, total lift was reduced to just below 75lbs.  Best of all, the addition of the Werks1 rear diffuser increased the vehicle's coefficient of drag (or Cd) by only .002, from .313Cd to .315Cd. What this means is that the downforce created by the Werks1 rear diffuser is essentially "free", with no negative side-effects to be found.

Because of the 911's rear engine, rear wheel drive design, and tendency to oversteer, traction at the rear wheels is critical.  The Werks1 carbon rear diffuser provides greater traction at the rear wheels during high speed cornering, reducing the potential for oversteer and leaving the driver with a tendency towards much safer and predictable understeer.  Best of all, installation of the Werks1 rear diffuser is simple and easy, using existing mounting points on the car with no modification required.
