Ah, ok.. Cool.. I missed that air curtain part.. They really did do their homework when designing the Gen 6 and seem to have really paid attention to the issues that needed correcting from Gen 5.

I did it at the shop and it took me 45 minutes. Remove the wheel, caliper, and rotor. Pull the rotor backing plate. Use two of the backing plate bolts to install the ball joint heat shield. Remove the small air guide on the control arm by taking off the three bolts holding it on and replace with larger air guide (be careful with these, they are more like screws and don't thread in very easily). Reverse order when putting everything back on. Remove tire deflectors (toward front of bumper) before track use by removing 5 bolts behind them. Leave them on for city driving, they will help with fuel economy. And don't forget our wheels torque to 140 ft/lbs!!!
