How long and how well will the ES motor mounts inserts hold up to 300+ wheel hp. Since jwt and Place Racing motor mounts are on back order for 5-8 weeks i needed somthing. Let me know whay you guys think.

I ran them with 350 whp for over 8 months! They worked fine!

Thanks Louis, I was hoping to hear that

You know what's funny though? My car made 333 whp. Ran fine! The inserts were great! When I blew the headgasket, I took the crossmember out and lent it to my buddy (inserts included). He completely destroyed the front one with CAI/Headers/Exhaust/Cams. No forced induction or N20; all motor and he blew them to hell!!! Really wierd!
