Do you have any install photos or tips for this you could share?
The front strut bar was not too bad. Separate the two ends from the bar and get those positioned on top of the strut towers. Install the 3 nuts on each strut but do not tighten. Then install the bar and the bolts that hold the bar to the brackets, leaving those lose too. Then tighten the 3 nuts on each strut, and then sock down the bolt on each side of the bar.
The biggest issue I had with the front strut bar was the top AC line - I had to bend it a bit more because the brace pushes down on it a little and made it hit the back of the TMIC. I also had to flip the AC line bracket near the master cylinder. Once I did that, all fit just fine.
The ladder bar is a bigger project. I placed the front of the car on ramps and completely removed both sub frames. Once they were out of the way is was easy to position the brace and catch the control arm bracket bolts to hold the brace in position.
Because the front tabs of the brace go between sub frame and the chassis mounts
, the thickness of the tabs have to be compensated for. You will notice that the sub frames have sleeves welded in where the bolts pass through. The sleeve that bolts up through the brace tabs have to be cut down (shortened) by the same amount as the thickness of the brace tab (about 3/32") to make the sub frame sit correctly. With the sub frames completely out, this is easy to do with an electric reciprocating saw and a metal blade. I cleaned up the cut with a file and painted the bare metal gloss black.
The holes in the brace lined up perfectly and the brace sat perfectly in place. With the modification done on the one bolt sleeve in each sub frame, they bolted right back up without any problems.
So, the GTSpec pieces fit just fine, though it takes a little effort to make them do so.
