This is such a broad question that I have to take the easy way out and punt.
There are many many things you should focus on. I'm sure you've picked up several from this thread alone, but I would highly suggest a racing school like Skippy or Bondurant to get some basic instruction and that will significantly narrow down your list of things to focus on. It would take me days to type what you would learn in 5 minutes at an intro to racing school during the opening "chalk talk". Well worth the money since you don't already have a racing license.
Also suggest reading any of the many racing/driving books to get an understanding of the basics.
We have yet to enter into racing school but all three of us have been tracking our daily drivers for years now.
After seeing so many guys come through your drivers school, what are a few things new guys like us can focus on as a good "first cut?"
If we are taking the SM to some track days to just shake it down and get the bugs out, is there something that we can focus on technique wise to not start getting bad habits? We wont have any data aq. on the car for now but is there anything you would suggest like posture or breathing?
If there were a few things that you feel take the longest to develop, therefore needing to start early, what would they be?
Thank you,
