I have the GNX brace also. For the price though, you can't beat it. Anything will help. I had to enlarge all the holes as I didn't have any bolts long enough for all the holes, even the holes on the shocks I had to enlarge. I had to wrestle it in place as my ATR tailpipe touches it a bit. I'll have that pipe cut and fixed on Friday. Even through all the crap I went through, it was an easy install
