Here's my poly loc ones. They only caused the suspension and header to hit since I had a strap. I'm seeing if these have a warranty tomorrow and going to buy the Schumacher mount that attaches to the k frame. My uncle and cousin have one on their 11 and 12 seconds cars with the regular auto parts store mounts and no issues. I guess I could be considered lucky it only messed up my TTI headers ugh.

Edit: They said I need to put a heat shield around mine and they have a 3 yr warranty. Also ordered their torque strap while I talked to them.
