Misnomer: I'm jumping in with an opinion...
"Yeah, I'll definitely do the brakes and upgrade the brake fluid.
Car and Driver also recommends brake-cooling ducts, but I've seen conflicting opinions on those. Plus I'm not going to be at VIR or living at the track or anything: I'll take her to one or two FATTs at Summit Point this summer, and might finally try an autocross event (maybe). I just want to be able to do that without overheating or going into a gravel pit. What do you think about brake-cooling ducts? Overkill?"
DEFINITELY NOT overkill! I tracked mine without them and had some fade and brake pad buildup so bad on the rotors that it felt like I had warped the rotors. Good news was that it was just buildup. Also drove the Dragon without them at ZDAYZ and had some serious brake overheating. I put the Stiller cooling duct kit on and did not have any more problems at the track or the Dragon.
Takjak2 is right, they are super easy to do. I think I could change a set in two minutes after taking the wheel off using a small Phillips screwdriver and some needle nose pliers. Easiest car to change pads that I have ever worked on.
