Anyone ever used these products? I see them sell on ebay and stuff. Personal experience with them? I met some fools that run a shop in LA, and are sponsored by them. Have a sick its71mm 1jz mkiii and a 1.5jz sc300 i believe. All CXracing parts on their cars. And those things held their own at the drift track. So I might start using these products. Just wanted some people to know if they were ever curious about them.
