I read today that some of the many porsche 911 models sold as street cars, come with solid motor mounts.

That said, is anyone running these? Is vibration an issue or something you can live with

I have never known anyone to use solid motor mounts and solid rear diff mounts in a batwing cover.

Why do you want to try it?

I'm still running the original, rubbery old mounts in my 84. Still working...

I've looked around for a while for solid mounts and haven't been able to find them.

I plan on making my own when my new engine goes in. Engine mounts, and batwing. Engine mounts just need to be a simple plate with a tube welded to it for the bolt to go through, and the batwing bushings I am going to machine from aluminum round stock.

Drove a Mustang with solid mounts, probably about a 300hp car. Stupid period. Best comparison would be to take the firewall and floor pan out, sound level is about the same and it isn't a pleasant sound, just noise and a lot of it. It was a 5.0 with a stick and I swear the car echoed with every gear tooth and every lifter and the vibration made the mirrors useless.

Would never do it to my own car now unless I had so much power I couldn't keep the rubber ones together.

NitrousSam made some back in 2006

Maybe you can find someone with them to post up.

I have been waiting to hear myself.

I have solid engine mounts and poly batwing mounts. I honestly didn't notice much difference in vibration from the original engine mounts.

I seem to remember a few of us bought some from Sam and they were well made. There were some threads/posts regarding all of this by Jeb Burnett, which includuded fabed c beams and making everything solid.....back when...

For what year car?

The ones NitrousSam made were only L98, didn't work for LT1

1994 chev 1/2ton pick-up SIX CYL 4.3 engine mounts are bolt-in sub for L98 mounts, but not silicone jelly filled (they found a better use for the silicone, see 'dancers' at most pro football events)...the truck rubber mounts are under $10 ea at napa.

'96 -- I made my own. Some plate steel, 1/2" ID steel bushing stock, a cutoff wheel and a welder.

Kubs

My thoughts exactly! Its not that hard of a project.

DVNCI

Unless you have zero fab skills like myself.

Someone could make some good coin by selling some LT1 mounts.

NitrousSam

We haven't made any solid engine mounts for a couple of years. That little project all came about because I needed a solid set for my nitrous 406 that was going into my weight reduction project. When the housing market and economy started fading I had to refocus my energy on our real estate business and the cars and automotive projects were all put on hold. I haven't been on the forum in quite a while but now that the housing market is rebounding in our community I'm gearing up for some fun with the Corvettes once again.

I remember a post you did once about putting together a solid axle kit. Any thoughts on starting that up again?

NitrousSam

The solid rear is certainly something I'm very interested in but I want a ride height that is lower than stock all the way around. We did a coilover conversion on the front of my 84 and we can drop the ride height pretty low so I don't want the rear end sitting high or looking like a truck. Before we start working on the rear end we want to try and get a 10 second time slip with a 36 still in the car with a soft launch. The thing we have going for us is our C4 has gone through some serious weight reduction and we have plenty of power to make up down track for our softer launch.
