so it is hard for me to conclude the bar chart is valid and the net change vs. stock is zero. thoughts?
I also questioned that bar chart and asked RR to publish all of the relevant numbers on their components for calculating bias somewhere fairly early on in their big thread about their brake kits. I was subsequently crucified for posting in their thread, told I had poor forum etiquette, told to go look up the information myself, etc. We subsequently ran the calculations using the standard Wilwood components, and determined that the bias numbers we found are definitely not optimized for the majority of our customers (mildly modified cars attending autoX, track days, HPDE, time trials, etc.).
