Please Read entirely Extensive-Experience/Opinion
First I want to say this kit fits just as it should and does exactly what they claim That’s t why I give it 5 Stars
LOCKS DOWN CRADLE RIGIDLY!
I chose this kit for My 2017 GT Performance Pack 373 gears, @ 5000 Miles, instead of the Steeda because it came with the heavy duty subframe brackets which are an absolute necessity if you plan on locking down the cradle and eliminating any give what so ever I’m sure without these extra heavy duty brackets that the cradle bolts would be absorbing all the force and vibrations at back which no doubtedly would end up at very least coming loose over time, these brackets also serve to keep cradle in align, I also installed at the same time the Steeda alignment kit that is made to go with BMR’s cradle lock down kit, combining both of these kits made it absolutely impossible for the cradle to be fastened out of align, With car on jack stands at rear pinch welds, I supported rear end with floor jack at center and unbolted only one side at a time starting with driver side then lowering it down just enough to get top cups in place put a touch of silicone grease inside cup to help it settle into position when you start to torque it down. For me everything went into place and aligned finger tight , then I torqued it down to 129 ft lbs, repeat steps for other side. This almost went the same But I had an almost impossible time getting the front right cradle bolt started, the back one aligned finger tight without any problems but the front was far enough off center that with alignment post and the bracket if inserted in the bushing it wouldn’t allow the bolt to even start in the threads So I loosened driver side but that didn’t help either the only way the bolt would start was if I Kept the bracket and alignment post at the bottom edge of the cradle bushing then the bolt would barely start due to length which concerned me it may cross thread or strip out before it was started good, to help I put a touch of oil on bracket post and alignment dowle so when I started cranking on bolt it would help the bracket slip over up into the bushing hole and slide into place, after that I was able to torque it and the other cradle bolts down, Warning the cradle bolts have a self aligning type thread at there tip so it would be VERY EASY TO CROSS THREAD IF CAUTION IS NOT TAKEN OR AN IMPACT WERE TO BE USED.once this kit is installed your Cradle is no longer Rubber mounted or isolated from the metal chassis, which DOES make any HARMONICS-road noises, rear end noises, driveline noises you had previously much more NOTICEABLE , Listen to your car CLOSELY PRIOR so you will no what to expect. IF YOU DONT PLAN ON TRACKING YOUR CAR DONT INSTALL THIS KIT YOU DONT NEED IT. Prior to this kit I installed Steeda adjustable differential bushings 80 durometer, it too effects Harmonic noises slightly . MY REASON FOR TRYING THESE COMPONENTS WAS HOPES THAT IT WOULD LESSEN THE BUMPING SOUNDS MY CAR HAS WHILE SHIFTING GEARS AND LETTING ON AND OFF ACCELERATOR INSTEAD IT MADE IT WORSE, I know the kits purpose is to eliminate wheel hop My wheel hop was eliminated by removing the Perelli P Zeros and replcaing with Michelin Pilot sport A/S 3 for winter and super sports in the summer .
My finale thoughts are that, Ford has rubber isolated all components of the IRS to control ITS HARMONICS AND ABSORB ALL THE DRIVELINE NOISES AND LOAD SHOCK THAT EXIST, MORE SO ON MANUAL TRANSMISSIONED MODELS AND PERFORMANCE PACK CARS WITH 373 gears, BY DOING SO YOU gain longevity of all components attached when a car with this much power is driven Hard Day after Day all while still surviving stop and go traffic!
I am a retired Auto Technician
THERES PROS AND CONS to this kit!
An everyday driver with no intentions of going to the track will see no positive gains He will hear all slack in the driveline more than before, knowing long term it can’t be good for all the components involved.
My car has always had driveline clanking in stop and go traffic but now it is way more distinct. I can hear everything that is going on in rear, even over My cars Corsa Extreme Cat Back Exhaust.
I will be removing this kit when I install the
Ford Performance Track Handling Suspension kit.
If you go to the drag strip ALOT with your car then this kit combined with other rigid components is a must.
