Paul that beam plate on the race car is sitting parallel to the chassis, so yes in that example it is completely correct.
However that is a very modified race beam designed for that exact application with solid mounts only and also its not a standard road shell either.
There in lies the issue, the height of the solid beam mounts as originally designed for such an application, if you fitted the Ford rubber mounts into that race beam then it would sit higher than it currently does, having the opposite problem to those fitting solid mounts to a road beam.
Facts are facts, sat side by side with a rubber beam mount there is a significant depth distance with the sold ones, I do not understand why people cannot see that. That difference does not simply vanish somewhere.
