The new CFM Performance mount is much firmer, with a 85A durometer rating, than the factory mount. Using all four of the inserts included will increase bushing firmness to handle higher torque levels achieved from custom tuning and the installation of aftermarket bolt-ons.
By selecting the optional 9 insert option when making your purchase, you will have enough inserts available to increase the rigidity of the mount substantially for applications with even higher levels of torque. We have tested our mount with great results and feel this is the ultimate lower engine mount for your 2016 Focus RS.
There are no other mounts on the market that can be fine tuned to your needs.
