Second time at laguna- not a great lap to be honest, but it's the best i could string together this day. Brakes don't have a ton of high-speed bite after they're heat soaked, which was pretty annoying. Stoptech ST42 kit w/ ST43 pads are going on next. I've seen too many C43 rotor failures to consider that kit, so i'm not risking it. We'll see how this incremental upgrade goes.
Splitter still overpowers the wing, so i'm running a ton of front bar and dealing with the mid/low speed understeer just to keep the high speed stuff from getting too squirrely. Will dial out the rake eventually to balance things back out a bit before moving to nine lives wing.
Spring rates and overall platform didn't seem too soft for this really low ride height today. I dragged the splitter around a bit but it's not worn too much, especially with the upwards deflection compliance shown in my walkaround video.
RT660s are wearing REALLY well compared to the CR-1, so that's pretty cool. Not interested in blowing $300 in tire wear per event anymore. RS4s lasted 12 track days, CR-1 lasted 3 (granted those were 100F+ days). Expecting to get ~7 out of the RT660.
