Best filled motor mount durometer?
If my motor mounts are okay on the stock car, I'm going to fill them, except the front, because I have an AWR, and put them on the other car. If they are bad, I'll dig the rubber out, and fill them. I'd like to know what durometer those of you who have filled them are happiest with, and what product is the best value. I have read all I could find, but couldn't come up with a consensus.
Thanks
Thanks

Re: Best filled motor mount durometer?
You know the tradeoff Jesse!
Stiffer mounts = Less flex, at the cost of more vibration. As you are inclined heavily towards performance, I would assume you would like stiffer mounts! I am waiting for solid mounts myself... They're just a bit too pricey brand new, for my tastes. Waiting on a used set!

Re: Best filled motor mount durometer?
Werd up.
Here's what I'm thinking; The AWR is 88, but the actual poly in it is about 1/2" thick. The Poly would be about 2" thick, when I fill the MM, so, if I go with a harder durometer, it would give about the same amount. However, I read a long time ago, that it's better to not put too much pressure on the rear MM, but that could have been from PT, since their setup isn't as good.

Re: Best filled motor mount durometer?
IMO Devcon URETHANE LIQUID FLEXANE 94 is the best two part rubber. If you find it too stiff simply drill a hole or two in the mount to relieve some of the rubbers stiffness. This product is meant to completely replace existing rubber parts.

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: Best filled motor mount durometer?
Can't comment on McMaster but when I was done doing my mounts I had lots left over and I completely filled my mounts. Now in case people read more into this than what there was I didn't gut my mounts as the rubber was good. I simply filled them, you know, removed the voids as they weren't doing any thing anyway.Nd4SpdSe wrote:My 1lb of the McMaster stuff was JUST enough to do my set of mounts for my car....Daninski wrote:IMO Devcon URETHANE LIQUID FLEXANE 94 is the best two part rubber.

Thanks
I've decided to go with a lower dorumeter, since I have the torque strut. I'll get the flexane.
