Are there any cases of the whiteline product tearing a subframe? There's so much negativity in here yet no links to problems? Infact, is there ANY evidence of subframe while using a reinforcement kit which incorporates the LCA bolt. Here's my opinions of the whole swaybar reinforcement idea.
When one wheel is forced into bump, the swaybar will try to pull up and away from the subframe through the D-bracket. Facing the hubs, you have a large vertical force upwards, and a smaller horizontal force away (relative magnitude depending on the location and orientation of the endlink and the relative positions of the swaybar mounting points on the D-bracket and LCA). The other side of the swaybar will see the opposite forces.
With just a D-bracket on the subframe, it's easy to visualise how a large vertical force will create a torque about either the upper or lower bolt depending on which side you are looking at for a given movement. You can test this with your hands - make a solid D-shape with your index finger and thumb and place it on your desk. Put another finger in the D and push on the inside of your index finger to simulate the swaybar.
When the LCA bolt is incorporated it will take the vertical load in it's stride. I guess it all comes down to, how well can the LCA subframe mounting bolt take unintended loads. It is clear that this section will be subjected to high levels of compression and tension through the axis of the axel - how strong is it under vertical compression and tension?
I've have the whiteline kit on my DA for over 2 years now. Until that LCA bolt moves, the rest of it is not budging a nanometre.
