its possible if you can get the car high enough off the ground on stands....you have to lower the cradle some so there has to be room to have the jack under it and still be able to work on it....you have any hobby shops around you where you can rent a bay for an hour or two?

i thought about that when i did mine...the oem bolts arent that expensive tho and my local dealer had them so i didnt do any further digging on the matter...

Wondering, is this the best bang for your buck when it comes to a suspension modification? That is, without going down the rabbit hole, adding this and adding that, sometimes it never ends.

From what I've seen and read, yes. However I'm taking it a step further and doing the upper and lower trailing arms as well.

So, to add to this: Bang for the buck! I took mine out this evening for the first time from getting it back and did a data log, 3rd gear pull. All I have to say is WOW, was I over impressed.

First, this car is crazy big on power! I mean,to have someone explain that kind of feeling, being pushed back in your seat when nailing WOT is one thing. But, to feel that add also it holds you pushed back in your seat through the entire 3rd gear WOT is something totally different, and awesome!

Since going full rear BMR parts, I'll say this! This car HOOKED immediately (16psi in the MT ET Street R's), and through the whole WOT pull, it went flip'n straight as an arrow and there was NO fighting the dreaded rear torque steer! I was overly impressed with how it handle the WOT power!

This is the first time I've had all the BMR parts installed together, full rear end suspension, rear cradle lock out kit and bushings, and this is with the new build at 1006 rwhp build. Prior to that, even with the rear cradle lockout and bushings, at 785rwhp, the car would not exact go straight (same tires) and I would have to guide it straight by using very slight wheel input. Maybe others can jump in and explain their before and after. But this was a hell'of'a ride this evening!

I can't stress enough for me, with my car having even more rwhp then before. I feel the BMR parts are essential if you want all the positives I described above!

LOL, I would expect to be pushed back in the seat with 1000 hp.
I'm stock power and just want to eliminate some of the squishy side to side feeling when I'm playing in the twisties. I've been pondering where to start for an improvement, without throwing the kitchen sink at it, so to speak.

Cradle and diff lockouts are a great entry level mod that will help cars of any power level. They’re mandatory at big power levels though.

I did mine on the ground. It took a weekend, but part of that was I replaced nearly all the control arms, too, so that took a little extra time. It's possible - just be safe and use jack stands and use safety.

Remember, after replacing the factory suspension parts with aftermarket parts, you will need a rear-end alignment most likely, to be safe!

Not anymore hard to do with a jack and jack stands

I got neglible if any NVH. However with my 15 Mustang GT PP car using a similar kit i could really hear the rear gears on the highway with the radio off.
