Solid motor mount questions
Solid motor mount questions I'm not concerned with noise, vibrations, or rattling change in the cupholder. Just looking for some feedback concerning peoples experiences and knowledge of solid motor mounts as far as setting off the knock sensors and/or damaging the block or other problems. I've heard some folks get false knock retard from the excess vibrations. I've also heard that I should be concerned with the mount bolts pulling out of the engine or cracking the block because there is no give with soild mounts causing the soft aluminum to break.
Anyone have 1st or second hand experiences with solid ls1 motor mounts??
Input is greatly appreciated.

Jarring, rattling, vibrations, etc don't really concern me. I actually like the race car feel. I know there are some folks on here that have solid mounts as well as daily drive them. I'm hoping some of them will chime in here with their experiences, opinions, and installl tips.
Thanks for the advise though zlover129. I'll probably end up going with prothane poly mounts simply do to the lack of feedback on the solids.

I'm running an LT1 with solid mounts and have been for over a year, the car is driven regularly and I just got done with an 1100 mile trip in it. Despite a slight increase in vibration I've not noticed anything negative. The bolts need loktite to stay put but after that you can forget they're there. I could say the motor felt more responsive but that could be all in my head, I have no way to test it. I've not noticed knock either.
I've not got an aluminum block but I've seen no stress issues from vibrations, everything I've heard and read is to the effect of "I've heard they can crack the block is this true?" I would think that if someone had cracked a block they would have posted about it.
In a nutshell, I like mine, I like the way they made the car feel.

This guy deserves a prize!! Thank you for your input!
It seems like no one has anything to say on the subject for the most part. Your the first person to actually post some useful information 4 me. And thanks to the few folks that have PM'd me too. Did you get the ones form Madman? How hard was the install?
Still looking for some input from the ls1 guys. I know your out there, don't be shy!

ill let you know as soon as spohn makes my k-member/a-arm/solid mount package and ships it. i figured i could deal with any vibrations and all that junk. ill keep you posted.
EDIT- and all the cracked block, knock sensor, and heroin needle in the mcdonalds playplace is probably just urban legends.

Ive got the Spohn mounts on a PA K-member, vibrations arent that bad, I dont daily drive the car though.
On a side note, I dont know what was out of whack, the K member or the mounts, but it seemed to raise the engine about 3/4"

At the current time I know my power doesn't warrant the use of them, but I like the feel. I know they will perform better than stock. I was also under the impression I wouldn't have to worry about screwing with the drive line angle which I've read can be a problem with some poly mounts. I'm also not much of a mechanic (nor was I blessed with a very fat bank account) so I thought I'd install these while I'm doing my headers this month and never have to mess with them again.
That sucks. That's one of the reasons I was thinking of going solids. Hard to tell if it was the K-member or the mounts though huh?

From what I have read all the people with solids seem to like them and the people that advise to avoid them run poly and have no experience with them. I have stock mounts for now but when i change me headers i plan to go solid.
Ive had both, dont waste your time with the poly ones, you will save more weight get about the same amount of vibrations, but it will feel a little more soild with the solid motor mounts. I didnt notice any change in height when i installed mine.
Well, after much debate I have decided to go with the solids. I will post up to share my experience with them. I just have a few more things to get together and I'll be installing them along with my LT's at the end of the month. Hopefully all goes well.
Anyone have any install tips on the solid mounts?
