Couple notes: magnets will do just fine on a road course. I've yet to lose one.

Also, I love your "save my expensive contis" comment. The RS-3's will blow them out of the water on a road course. You're going to LOVE them. For 140+ TW street tires, they're about as good as it's going to get for road course events. They take heat and beg for more. Use them for autocrossing too (assuming you're probably running STU?)

HP+ are still going to beg for mercy. You're in MN, so Road America? I would absolutely recommend changing your brake fluid to at least Super Blue, but I would highly recommend stepping up to Motul RBF600. I autocrossed for three years and got very good at it before taking my Z4 to Mid-Ohio for my first track event. I had HP+ pads on it on street tires, oem brake fluid. PDX's are like autocross in slow motion, so if you're any good at autocrossing, you'll quickly start pushing your car hard at the track. I did, then my brake pedal went to the floor coming out of thunder valley. That's an eye opening experience in a daily driver. Long story short, if you're doing HP+, bed them in correctly on new rotors, and switch to Motul RBF600 fluid. Or, conversely, don't brake the ever living piss out of your car.

Have fun!
YES! BRAKE FLUID BRAKE FLUID BRAKE FLUID.

I had mine boil on my 330 and then on my M3. What can I say.... I like to brake late on bad fluid. Both were bad experiences. Switch to some RBF600 fluid so you don't have your brakes go out at the end of a straight like I did.

I was going to go for the Schroth quick fits, but ended up deciding to keep the money

I go the 75mm studs too. They make putting wheels on like 10 times easier. More than worth it to me since I've had them off the car nearly every weekend lately. I'm running 15mm spacers on the front though, and I shouldn't do that with just 75mm studs, I need to move up to 90mm to be safe. (I don't run the spacers on the track)

Keep an eye on your coolant and oil temps, and have fun
