Thinking about grabbing the IRS subframe alignment (just the inserts, not the entire lockout kit)

Im literally only wanting them first rn peace of mind that things are aligned correctly after dropping the rear for spring or whatever. If they offer any other benefits great, if not, not big deal.

Anybody use them? Experience with them?

I think they are quite popular (I have them) :like:

Someone will be along soon to tell you they really firmed up the rear, and stopped some wheel hop etc etc … :giggle:

Right on. Did they increase any cabin noise for you at all?

Wheel hop hasn't been an issue for me. The trick is having much more power than the tires can handle. Then take offs are butter smooth😂

None at all - it’s already a solid joint, and we just add a solid spacer to keep it centralised and to add repeatability :like:

I have them, but installed like 5 different parts to stiffen the rear at the same time, so no idea.

I’m in the same boat as CoyoteRacing. I installed them as part of the Ultimate Handling Kit. Install was super easy. Can’t say what benefit this individual item gave me, but the kit is solid and worth the price.

I did the inserts and the collars at the same time, as well as the IRS brace and sway bar... No extra NVH that I can detect... Definitely made a difference for me.

I just put mine on this past Saturday, install was easy peasy. You should do the bushing support collars too, the go in the same place and you have to remove the same bolts, so why not install them at the same time.

I have them, I did it when I lowered the car to make sure the cradle was spot on center.
