My first time at Laguna Seca and 10th track day in my new(ish) M2.

I had just spent the previous day getting used to the track and had ended with a best of 144.3. I aimed for 1.43's and got it...and here are my best 2 laps.

It went downhill from there... WOW Laguna is especially hard on your car...especially the brakes!. I came here with brand new EBC Yellows on the front and newer stock rear pads and rotors that saw 2 wet days at sonoma. By the end of the weekend my rear pads are down to like 1-2mm and getting pad warnings. And I'm not sure I like EBC Yellows too much. There were several times throughout the weekend I would get fade, and one time caused me to go too hot into turn 5. Also had some weird intermittent issue where I'd get a really bad wobble and vibration after hitting a turn hard. I'd get out and check in paddock and went away after a few min. @chrispy28 was nearby and mentioned spacers, which actually I think he's onto something....

But great weekend overall and thanks again to @speedsftrackevents8380 for another great event!
