This is what I was getting at. Drag racing and pro touring is one thing. Endurance racing is another. F1, Nascar, GTLM, GTE, GTD all run Alcon, Essex, or AP.
There is nothing wrong with Wilwood, but they are not on the same level and do not carry the same pedigree for long term reliability and durability. Now for 99% of the people out there that truly have no idea what they are looking at, they probably look like the best thing in the world. To those of us who have owned Wilwood, Essex, and AP, we know the difference.
To further elaborate, I reached out to Wilwood regarding the kit with some questions regarding testing metrics and results. They clear as day stated that they do not conduct any performance testing and have no data available. They do not have the resources to conduct such testing. How do you market something as an "upgrade" with no data to back that up? They lost some points from me for deceptive marketing.
With that said, I still have not ruled out running them on my truck because they will fit under 17's and I know they will perform better than stock. At this point I am trying to determine their rotor offset because I want to know if I will be married to their overpriced branded once piece rotors.
