How did that end up working out for you?
I didn't like the vibration at all, but I did like the responsiveness.

Honestly, Ive got them installed along with the motor all though I have yet to crank it up! I'm getting reader to install the headers, plugs and wires hopefully tomorrow. Then I have to modify my radiator support for the SLP lid conversion! I've been extremely busy with the new little one and the xtra hours that I have been putting in at work, Military go figure only if there was over time pay that would awesome, lol! I'll let you know how it goes though, thanks for asking Steve

I just installed my Spohn poly mounts. Install was easy. Changed my oil pan gasket and steering rack to a LS1 rack and steering knuckle while I had my k-member dropped. Didn't notice any more vibration than was already there because every other peice is either poly or solid. Car rides firm, just the way I like it.

What??? Is this something you know first-hand, or heard about?

We'll see. Got to be better than stock in my opinion, lol! Everything in my car by the time i'm done will have brand new poly mounts all the way around. I hope it drives different considering it's a 94
