I considered those for my project car, but I'm still in doubt.
Basically, for the reasons that were already stated in this thread - eventually something will break due to excessive vibrations and that's not gonna be pretty.

As I read it aluminum motor mounts put chassis stress on the driveline, hp isn't the main factor, its how much twisting and other forces act on the chassis which is being held rigid by the drive line. Potholes, speedbumps, and drive ways being more important than hp or torque.
Just my speculation, but seems like a track car with a full welded cage might have less issues than a street car.

That cage needs to be extremely well engineered for this application and tie in both the front and rear mounting areas, however. If the cage stops just before the mounting area, the twisting loads will be more concentrated in a smaller area and make the problems worse. Think of "gentle bending" over a large area versus reducing that area and "kinking" things. Most cages will tie into the suspension pick-up points, but will not address the actual engine and transmission mounting areas. Most cages will make the problem worse, therefore.

What's the difference between collapsed mounts and solid aluminum mounts other than engine clearance? Is that what the OP is looking for, better engine clearance underneath?

Here's the reality of all this:
There are people out there that will manufacture anything, if they think they can make a buck, from it. They don't care who they steal the idea from, they don't care what it does to your vehicle. You have to be the one to decide if you really need what they make, or not. You have to be smart enough to think the whole situation through and decide what the long term effects will be.
This just happens to be a good example. If there are successful race cars not using solid mounts....you probably don't need them for your street car....

The difference is that the collapsed mounts still have rubber and allow things to move/flex/twist. Solid mounts do not. They are metal bolted directly to metal. No flex.
So, yes, Kibort has the right idea. A set of dead, collapsed engine mounts would be better than a solid mount...and lower the center of gravity, some.

That's what I meant. You might as well leave in the collapsed mounts.
Not sure what the OP is looking for.

I do not know why anyone would use a solid metal mount on either the engine or trans.
If they do, they are looking for trouble down the road.
FWIW.
That cutlass of mine that had the solid plate on the front of the engine (earlier post) the vibration of racing for one season spyder cracked the entire crossmember making the car no longer useable.

Maybe that's why Carl uses them for his race car? After all, his engine is making hundreds of horsepower more than Anderson's and Fan's.
