Of the cars I have personally installed HDKs in....over 25....I have never noticed even ONE that the sheet metal was pushed away significantly from the factory upper shock mount.
John's car had no modifications as mine did but yet still he had the same thing happen. Are these unique situatiions?
Would be easy for anyone to go look at their shock tower support and look through the hole and see if there's a gap between the support and inner fender. If those two parts aren't COMPLETELY mated together, there's going to be some crush there. Regardless it doesn't bother me all that much. I'm looking at what I'm getting out of the kit in the end.
