A full update on my video yesterday:
I went to Laguna Seca for a 2-day driving school with the BMW GGC club, it went pretty great. It rained the first half of day 2, but otherwise decent weather. I was worried about the car as the first time I tracked it, everything went wrong (oil temp, fuel starvation, stock brakes overheated and burned out so badly they stopped working entirely and I had to limp home with the e-brake..), but the upgrades seemed to fix everything
I'm running the stoptech slotted rotors and pads now, and there was *maybe* a tiny bit of fade on one lap, but otherwise were perfect. With the oil cooler my temps were about 220F on the track (160F highway) so nowhere near limp mode. My new sway bars are still at the softest setting, but it did seem to be noticeably flatter in the corners.
I'm pretty happy to know my Z can handle a track day now
Can't wait for the next one.
