Diff bushings or lockouts for diff?

[Vasbinder]

Wanting to install differential bushings, will the polyurethane bushing have nvh or will the bushing lockout kit from steeda be less nvh out of them. Also going to install bearing on the Lca when I have it on the lift. Car is a daily driver

1. We need the details of your car, and what mods you've already done to it. Put it in your sig-line, like everyone else. We do it for a reason.

2. What are you trying to accomplish?

I've got the Steeda kit, and don't really notice any extra noise, but then again my exhaust is loud.

Either one will increase nvh to some degree no matter what the manufacturers say. Like above tho if you have loud exhaust you prob wont notice. The LCA bearing will add a bit as well.

I have the Steeda stop the hop kit and I can honestly say there is zero NVH added from this. All positives, no negatives.

Differential bushings on the other hand I do not have but from what I've read from other users and the manufacturers these will increase NVH.

This testament is echoed not just by the manufacturer but also by the users of these parts.

Isolate the subframe, leave the diff alone.

That's why I asked what the OP wants to achieve. It's a mod that makes no sense by itself.

Car is all stock as of now. I have kooks, injen intake and a 2018 Intake manifold with a custom tube going on when I get the suspension set up. I have steeda vertical link and bmr rear toe link, waiting on install. Car is my daily driver and I beat on it on the back roads. Going to get a P1x procharger on black friday. Just trying to set it up, so I dont have to do it again. I figured polyurethane bushings would be better since it's a whole replacement piece. Not just a filler piece in the original bushing.

Going to get the steeda rear brace and I have the subframe lockouts and centering bushings

Don't do diff bushings if it is your daily or you are not attempting to set any records.

I highly regret having them installed on mine

The nvh is very noticable

You may ask why I did install.
Well I did this before the car was delivered. Springs, CB005 was being installed so I thought why not the bushings as well as I wont be touching those parts again.

I have though after that installed the subframe alignment kit which was much needed.

Is it a Performance Pack car? Does it have the 3.73 Torsen diff?

No, just a premium

This, highly regret doing mine.

Just do the basic Stop the Hop Kit. I also had no extra NVH after installing that along with the brace.

 

[Vasbinder]

When I had it on the lift, I could see the diff bushing

This, highly regret doing mine.

My thoughts also, if I was doing other suspension, just do it all. Now I probably dont need diff bushings
