After driving this for 3 days.

This mod made the whole car feel completely alive. this is definitely the best mod i've ever had. and i've done it all besides motor mounts.

The Urethane cures into a rather low durometer material. I can't imagine it will be nearly as stiff as inserts or urethane replacements. But I feel this could possibly be a solution to the movement without being overly harsh on NVH.

I've used several types of motor mounts, but the Windo Weld'ed stock mounts were my favorite. Perhaps I will try this just to see how it does.

Any updates? I made a thread about window weld mounts and nobody did it on our cars yet.

I could probably deal with a clunk, but I wouldn't be able to handle constant gear whine on the freeway.

I don't notice any whine on the highway.

Over 100/110km/h?

jvincent · 07-27-2014, 08:01 PM

Yep. Usually doing 120/125. I have Motul Gear 300 in my differential, so that may be a factor.

Maybe your oil is better? I don't think so... But maybe...

jvincent · 07-27-2014, 08:37 PM

Could be. Or I might just be deaf at that frequency now.

Hawk77FT · 07-27-2014, 10:55 PM

i hear a hum, like is metal on metal type thing, in the 5th at about 60-70 km/h. Is that normal? It sounds like is coming from the diff, but i am not sure.

Mikepage · 07-28-2014, 08:10 AM

Yes, If you have all bushings we have, then yes it's probably normal.

Just installed this tonight. Anybody else notice a vibration from 4-5k that you can feel in the pedal? Its almost like the drive shaft is not balanced correctly.

Mikepage · 07-31-2014, 07:41 AM

Mmm i don't think i have vibration in the pedal.

You have only rear diff bushings?

Rear Diff, Rear subframe, ForcedFab/Whiteline transmission mount and shortshifter/polly bushings.

Hopefully I didn't tweak something during the install. I did the rear sub frame at the same time, I had some issues with that install and was raising and lowering the rear subframe quit a bit. Its a weird vibration, Cant tell if its from the drive line or the engine itself.
