What have you guys done to relieve any vibrations inside your 86? - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Quick update: Went to the local crafts store (Michael's where I live) and picked up some cushion foam. The rattle from the back comes from the 3rd brake light's mount.

Open your trunk, look inside the ceiling of it, directly in the middle is a hole that will show daylight, and a black wire heading up through it. Cut some blocks from the foam and stuff it all deep inside that little hole, there is yet to be a YouTube video showing this method, they usually tell you to put the foam in "any hole you see". The hole I mentioned is the root of the problem, zero rattle ladies and gentlemen.

I think I have the same rattle. Noticed it more with the seat down during this last road trip. Will check. Thanks!

I stripped my interior and did a full damping/noise reduction treatment (Google sound deadener showdown for guides). It definitely cleaned up my interior of any creaks, squeaks, and rattles. I'm completely satisfied in that respect BUT highway speed wind noise is still an issue for me(60+mph). I might need more melamine foam coverage in the headliner as I only had enough to cover a piece. If anyone has successfully tackled high speed noise that would be good info. Under 60mph in cabin noise is well controlled after treatment.

Tune your suspension for max softness. For the tires, what is going to matter is the sidewall stiffness and tire pressure. You want a more passenger-like tire, I'm running Michelin Pilot Sport 4S @ 35 PSI and it's a little stiffer than I would like, but if I drop it below 35 PSI my MPG takes a 1-2 MPG hit if not more. You may want to try to drop your PSI to 32.

I bought the Flex A hoping for more comfort but at 11-12 clicks I thought there was significant body roll in the turns so I settled for 9 clicks. After only 2 months I feel like the suspension doesn't dampen as well as when new.

Keep the rear seat backs up. A lot of noise comes through from the trunk area.

I turn the tunes up until the window buttons start vibrating then turn it down just a hair
