Dont be such a tart, it clearly says on the package.
"This Part is designed and manufactured for competition use only, and is sold as is without warranty. The entire risk as to quality and performance is with the buyer.
Use of this part will make your vehicle not in conformance with vehicle safety or road regulations, and the operation of the vehicle so modified may be illegal on public streets, roads and highways"
So you fitted it anyway and then complain its not that good enough when stood up in your garage lol
