I have heard these are pretty harsh.

Anyone use these and are they worth it?

 

I've had mine in for a few days. Harsh? Frankly, I'm unsure. I say that because the stock rubber mounts (one had deteriorated so badly that I was getting metal to metal) were worn out. In my case, the swap has made a huge difference--the car is simply much smoother. I'm still smiling!

I have them in my Z and can honestly say they feel no different to me.The motor hardly moves even with my cam when you watch it with the hood open,but I dont feel they are any harsher than stock mounts at all.I highly recommend them to anyone.

 

I have the Moroso Solid Steel Motor and Trans mounts.They are a lttle noisy when the starter is spinning, but I like the fact that they'll last forever and the motor can't go anywhere.The shifter doesn't even vibrate now, it's solid as a rock.Can't imagine the poly mounts being considered harsh, at least in my opinion.
The poly mounts should hold up very well, I
wouldn't hesitate getting them, if I were you.
Anything's better than the rubber mounts.
