Built with pride in the USA! Detroit Speed’s front subframe is a bolt-in replacement for the original stock subframe. It improves the handling and ride quality by utilizing Detroit Speed’s unique suspension geometry. It is the ONLY subframe in the aftermarket industry with hydroformed frame rails. The hydroformed frame rails feature strength and stiffness, precise quality and repeatability. Hydroforming preserves the steel’s strength and stiffness because it is performed at low temperatures, unlike traditional high temperature processes which decrease material strength. This subframe ended up in Kristian Nyberg's Speed Society built 1969 Camaro.
