Although this is more of an UTH topic, the problem only presented itself when the car was driven under track conditions, plus you guys know more

Here is the back story: Car is purchased used in 2006, damage measuring 1/2"x4" is discovered under the right side strake (looks like curb damage) a 3 months ago, when taken to alignment shop a month ago my mechanic says that he can only get -1.5* camber in the right rear and he says something is probably bent, he says that he turned the camber bolt and at a certain point it just starts spinning, he installs a bump steer kit last week and is still unable to adjust the camber and maintains that something is bent, this weekend at the track I did this to the right rear wheel and LCA:





FYI, here is a picture of the static LCA/wheel relationship. There is a ~1/2" of clearance between the two pieces.




The damage is very slight on my right rear street wheels and very pronounced on the track wheel. Car is on stock suspension. Alignment is -1.5*, 1/8" toe-in with Megan bumpsteer kit.

Before I get concerned about frame damage, I figured I would be able to narrow down the bend piece a little more with my symptoms. What are your thoughts? Thanks in advance.

 

Doesn't the megan kit require you cut/grind it to fit w/ stock wheels?

 

Yes, but the damage is from the inside edge of the wheel rubbing the LCA. The grinded bolt for the BSK lies at the mid-depth in the wheel. Although the clearance there is no more than a credit card, nothing rubbed.

This problem occurred, albiet to a much lesser degree, with my OEM toe arm as well.
