I have 56K on the clock when I swapped to poly motor mounts. I didnt think I needed new mounts until I took out the rubber stockers and saw they were pretty beat.

Motor mounts. Do it.

And have fun with them, LS1's AC is right in the way.

ok i got them in today im not doing mounts ill wait on them and pay the price if i have to. soooooooooooooooooooooooo who wants to help?? ill pay for your gas and buy dinner :-)

dude its like changing your oil and not your filter....

Don't rush it and try to get them in before the Nats. The chances of getting the headers and y-pipe all installed and lined up properly are slim. I would seriously wait until you can do the motor mounts at the same time. There's no good reason to rush the header install especially if you won't be able to get it tuned right away.

i heard that makes the car vibrate like crazy

With the poly mounts? Ive never really noticed any major vibrations, although im used to the cars and don't look at them like bmw's where you can't feel anything and they take every bump like a dream.

Seriously its not difficult
