By replacing the four rubber bushes that support the CL7's front subframe with rigid collar mounts, the body and subframe are directly fixed. By removing all the original rubber bushes and replacing them with aluminum rigid mounts, the body rigidity is greatly increased, engine vibrations are directly received, and engine power is transmitted to the transmission and tires without any loss. In particular, unlike the Accord, which is a passenger sedan with a comfortable specification, the color is dark, so the settings are all focused on ride comfort. By replacing the subframe with rigid collar mounts, the handling characteristics are greatly improved, and everything from braking performance to cornering performance and suspension movement is transformed into a sports sedan. Installation requires pressing with a press, so please ask a professional shop for help.
