You're in SoCal.
Are you a BMWCCA member? They run a totally SAFE track day experience, particularly for the novices. There should be an event coming up in November/December.
Keep DSC on and you'd have to be an idiot to crash. A lot of those crashes occur because people turn off DSC when you're not ready. My instructor went out in MDM mode and it never activated. If you're smooth, it doesn't get in the way for 99% of the people out there.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
