Sorry I was out of town, when this thread resurfaced.
The modification is basically re-drilling the mounting holes for the hyme joint. It is adjustable, and you can pre-load it, but the threads are not reversed, and you have to use a jack to raise the car a bit, to release suspension pressure.
I had to cut the tabs off about an inch, on either side, because the Q45 strut towers are closer than the I30 (FWD vs RWD).
The mod is easy, and can be done with a hack saw, hand file, and battery drill, in about 60 minutes.
I have full size pics of the bar installed in my Q45, and my I30, so email me, and I will send them to you.
