I really wish it had been solid wet, but there were a couple of run groups before mine.

I agree that I need a bit more oversteer. As I got faster at the end of the weekend I was noticing more and more understeer. Very rarely did I get any oversteer, but it definitely went more neutral in the trigger with power. In the corkscrew it just plowed with more power. It's pretty obvious in my videos too, the tire squeal goes through the roof as the track falls away and I roll on the power. Have you driven a BRZ on track to compare to your FR-S?

That rotor looks pretty decent. I'm not sure when I'll have time to swap back to stock pads, but my rotor has way less heat checking, but a bit more smearing. I wonder if I had more smearing because my braking zones were so much longer due to my tires... I was trailbraking pretty much everywhere, and did have some vibration into the loop, and the hook. Not really any noticeable vibration or pulsing anywhere else. I was bad about touching ABS into the hook over the bumps, but everywhere else it was pretty easy to manage threshold braking.
Yeah trigger was pretty hairy in the wet. I'm used to minor understeer in my car, but that first session, I turned-in on maintenance throttle and the rear just came right around. I caught it, but wasn't expecting it at all and put on a small show for the Miata behind me. There was some talk in classroom that in addition to the rain, someone might have dropped fluid there.

When my rear tires weren't so worn, it was much harder to get power oversteer in corkscrew. I had to downshift to 2nd, toss the car in, then get on the gas gruffly. Not sure it's fast, but fun I remember trigger being easier to get rotation on exit. BTW I've only ridden shotgun in a friend's BRZ at an autocross. It was definitely a bit more planted, but not a huge difference from the passenger seat.

Also glad to hear that the pulsing may be normal. I might just replace the rotors before my last event since some of the heat check cracks are spreading/getting longer. Peace of mind sort of thing.
