Inside the Rahal Letterman Lanigan RLL BMW M6 GTLM
The front fender is vented to release air that would normally be trapped in the wheel well.  The side exit exhausts are placed so their output feeds the side vortices that help seal off the underbody from air curling over the top of the car. This again helps improve the rear diffuser effectiveness.
A good view of the fender well venting and the exhaust system.  Air flowing out the fender vent also helps keep the exhaust cool.
The side skirt is shaped to maximize vortex generation. The rules limit really radical DTM style aero but the car strives to make efficient use of what is allowed.
The front splitter has a slight pitch up in the front to reduce pitch sensitivity. The nose getting low to the ground in heave can cause the splitter to touch the ground reducing the effectiveness of the diffuser by cutting off its airflow.  The pitch up helps keep air flowing even if the splitter gets close to the ground.
The M6 is in our opinion the most beautiful of the succession of race cars that BMW has campaigned in North America over the years.
We love the M6’s integration of radical race car construction mixed with quite a bit of production car.

The Rahal Letterman Lanigan RLL BMW M6 is a prime example of the sophistication of IMSA’s GTLM class.  We love production car based racing and this car is a prime example of the best of the best.

We recommend going to see this car run when the IMSA WeatherTech Sportscar Championship circus comes to your area!
