I posted a update to my first post. And will try my best to help anyone trying to get into this.
I have a decade of experiance doing this. Plus I am a licensed SCCA member and instructor. And have ran in many different classes. The rules are always changing but I have all the rules saved and keep upto date on a year by year basis.
And have a good grasp on setting up the 4th gen for this(through lots of trial and error). Plus I am always transforming my setup. And trying new setups if they show any promis of improvment
