AVO inserts/bushings
 

Hello,

Went to the local Drift-Office meet and purchased the AVO trans crossmember insert, and rear diff tramp bushings.
Installed them over the weekend

These two items, combined with perrin motor mounts, t-support for trans, rear shifter bushing, perrin steering rack lockdowns, added A LOT of NVH.

Note: If you have aftermarket t-support (perrin), you need to cut out larger diameter hole on the trans crossmember insert, for the t-support to fit.

Install is easy, but if you have a fatter rear sway bar, you will not get to the bolts that hold that diff in place. So, lower the sway bar by unbolting the way bar brackets (holds the sway bar and sway bar bushings) on both ends.

Also helps if you have a support on the diff.

Is the added NVH worth the benefits?

I want to say that the car has this "solid connected" feel to it...

before adding those 2 products, there was def. NVH, but with those 2 avo parts, it increased it by alot. I now feel like every rpm (dunno if that makes sense).

This is good to know since I am putting in my diff bushings tomorrow. Thanks Sam!

Take out the Perrin T it will dramatically reduce all NVH. I experimented a ton with such bushings etc, the #1 NVH maker is the Perrin T. Install stock T and you'll be amazed and still have a connected feel.
