BMR has designed the SFC015 for the street performance, drag race, and handling applications. This four-point design is far superior to other sub frame connectors on the market. The SFC015s solidly link the front and rear sub frame, where others only connect the front sub frame to the lower control arm mount. This does little to keep the rear of the chassis from flexing. Connecting both sub-frames and the lower control arm mount and transmission tunnel brace, these sub-frame connectors are the ultimate in chassis stiffening. BMR's SFC015 sub frame connectors are 100% bolt-in. This means they can be easily installed with simple hand tools, and no welding is required. When performance is a must, rely on BMR Suspension!.
