The crew is down in Charlotte today with the 818R and the 818S for a full day of wind tunnel testing. The goal is to qualify the aero performance of the front splitter, optimize rear diffuser angle, and validate combinations (rear spoiler and rear wing). Both cars are running carbon side skirts (although it looks like the aero benefit is next to zero - but they do look really cool). The number of variables to be tested merits a full day, but when we're done, we'll have drag and down force numbers complete for the street car at street ride height and the race car focusing on down force. More news later, but thought you guys would like the pics.
The aero package is really important to the 818 program since down force and drag in this design can render a tremendous performance difference and we also want to make sure the aero parts we are selling are validated to produce balanced (safe) down force. We'll publish the optimized data early next week.
