LS4 Front-Drives 2005-2009 - Upper Motor Mounts...Which is best??

Hi, my g/f has an 07 Grand Prix Base. The upper motor mounts are really soft and compress a lot.

I was going to get a set of new polly upper's but I am not sure which to get(W Body Store or ZZPerformance).

Any opinions on which is better, and or why one is $20 bucks more?

From what I hear wbody store ones are junk, makes everything vibrate a lot. ZZPerformance are better quality and better period. Also I think the ones from 3800performance MSP ones are the best on the market for our cars but there 70 bucks so I would go with ZZP a lot of people are happy with them

i went with intense's poly mounts and i like them a lot....not too harsh but you know they are in there and they arent real expensive

This is what I have.

And yes you can buy one

I just bought the MSPs. I've heard a lot of good things and am installing this weekend. Also, you can purchase one of them for $35 plus shipping. All you have to do is email them. I'll let you all know the results after this weekend.

Just installed the MSP Poly Mount yesterday. So far I've noticed a decent increase in throttle response. Not much noticeable rattle. The MSP mount needs a little trimming...see previous post....and I pretty well had to destroy the OEM rubber mount..but overall fairly easy install.
