Quick update on the performance of the plates. They have been excellent. Thus far, no noises , no pop, clicks or creaks. I was able to do one session on track recently (I had some brake pad issues which limited me getting to the track . I also attended an autocross last weekend. Wow slaloms are now MUCH easier. On track I already noticed i have to adapt to move my hands a little less when steering because less effort is needed.
I am absolutely loving these.
I can't report on tire wear really yet because I put on Hankooks rs3s on my track wheels and wear is minimal on street tires compared to race tires.
