Okay, so we had radicalDREAMZ (09 Si coupe) car in here today to test out the brackets and it appears that the Si has a new trailing arm. They added a bunch of gussets and for some reason they moved that hole just a tiny bit. I don't know if this is going to supercede the old part number and go on all new Civics or if it's just for the Si but we will be slotting that bracket in the future so it will fit on all of the cars.
For now we're asking those of you that have the bracket with misaligned holes to just open that hole up with a drill. With the right tools it's about 5 minutes of work. If you have any questions the best way to get ahold of me is
