I used different bolts that fit. The bolts that came with the brace are bigger. I did not notice much of a difference, however I have a GNX seat brace and another rear brace tying the rear frame together. You can see it in the above picture. It is tying the frame ends together.
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

After reading your post about the ATR tailpipe rubbing the shock tower brace, I may rethink my decision about installing this, because I am running 3" ATR dual exhaust and I really don't want to be messing with my exhaust system.
