I was very fortunate to get MrAngry in my car and get some feedback for the track today
He said that I needed brake and steering tuning. The rear brakes lock up way too fast and that I need to dial in the combination of my hydroboost unit, master cylinder setup and that I need to install a proportioning valve.
For steering he recommended the borgeson box.
Unfortunately I am not able to address the issues before my track day this Saturday so I will be driving very carefully 6/10ths as not to lock up the brakes and spinout.
He said some other stuff about the car that will be evetually be shown in a little video
