Subframe Bushings NVH - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Capt Spaulding · 04-05-2023, 08:38 PM

Good deal. I have STI engine mounts, a Whiteline trans mount cradle, and a set of shifter linkage bushings in my to-do inventory. Maybe one these days they’ll graduate to the been-done inventory. Just need to show them a few YouTube videos so they can install themselves.

Did you guys use loctite when reinstalling the subframe bolts ? If so... blue or red

Thanks

No. If anything, I recommend neverseize.

Capt Spaulding · 04-06-2023, 02:01 PM

I’m squarely with NHM. I recommend antiseize.

Thanks for making this thread.

My whiteline subframe bushings are coming in today. I'm also having the PBM diff riser bushings installed... fingers crossed for no headaches...

My subframe + diff bushing combo definitely increased NVH. Although not terrible, it is noticeable. I have a distinct "hum" around the 3k rpm range, however, the driving benefits outweigh the noise increase.

I have the Whiteline subframe inserts and diff inserts.

Doing some exprimenting, I just removed the front lower diff inserts and made a large reduction in noise for my car.

I went with the Whiteline subframe inserts and did not really like them. Then changed them to the STI stoppers, I did only the uppers and changed all the subframe bolts to STI ones
(they are longer).

And never looked back ever since.

How would you describe the difference between the Whiteline inserts and the STI stoppers?

Same for me. The front bushings on the diff are brutal. I pulled both upper and lower, but the lowers seemed to be the majority of the noise.

I'll add my experience...

I installed only the Parts Shop Max solid diff risers, and went from breaking an axle every drift event to not breaking one in 10 events and 5000+ miles. Minimal NVH increase.
