How are they on the street? Whats some part numbers on them?

 

I have the Moroso solid mounts, have been running them for a few years now. I don't even notice them anymore. IMO they aren't too bad, only vibration is really at idle, once off idle it tends to smooth out. Made the front end feel more 'solid' when I did them.

 

well i installed the moroso ones last winter i have about 400 miles on them, and there is a TON of vibration... i idle my whole dash and everything just shakes.. i have the trans out so i am gonna pull the flexplate off and see maybe if it isnt perfect in balance cuz it gets old fast.

 

I have a poly trans mount with the solid engine mounts to ease some of the vibration. I really don't even notice it anymore. I will try to get a vid once it's back together (rebuilding front suspension/new k-member).

 

I've never been in an LT1 car with them, only LS1 cars. The LS1 car I installed a set in last year felt 100x better with them over the stock rubber. If I could have acquired a set of solids the day I did my AC compressor I would have gladly installed them. Went with polys instead. If anything my car felt a lot better with the polys, which supposedly give more vibration. I felt none.
