Tell me if I’m missing something: I’ve seen some very nice mounts for sale that replace the entire diff mount. Aside from being marginally more work, why wouldn’t you just replace the bushing itself with an 80A PU one at a much lower cost?
I got the 034 street density mount in a few days ago and thinking of doing the diff bushing as well while they’re at it. Ordering the entire rear diff mount from the US seemed too much money with shipping and taxes for what it is: a piece of metal of identical dimensions to the one you already have on your car.
So replace the bushing in your OEM one vs replacing the entire diff mount? Sure it could be an option, but it won’t yield the same performance as an Apikol.
The Apikol unit is bigger (more mass) and billet (more rigid) with a collared and full poly bushing compared to the OEM unit. The OEM was a hunk of cast crap and the bushing sucks, even if you have the OEM bushing pressed out you wouldn’t get the benefit of the additional mass and rigidness of the newer style mount. The Apikol bushing is also fully enveloped in the unit, I don’t know how you would manage that on the OEM one.
The carrier mount bushing insert fills the gap in the existing bushing insert, thats where it absorbs the slop. Even if you went poly, you would still have had gaps in the bushing which would still be less stable than essentially making a solid mount.
Thanks that’s the one I saw. For 50 bucks it appears to give pretty much the same result. Not as pretty but then I don’t look under my car much anyway. I ran Poweflex stuff in my track car a decade ago and they held up forever.
c_t, I really don’t think the rigidity of the mount contributes at all to any benefit. The billet one isn’t going to flex on the car and neither will the OEM one. The load on the mount exist only lengthwise, there’s no lateral load. Whatever nigh immeasurable flex exists in the mount itself will be irrelevant next to the flex of even the racing spec bushings.
