From John Calvert himself.


We have seen mounts break or crack where the shock hooks up. I feel the main reason for this occurrence is how cars are transported. Tying to the rear end housing and allowing the body to remain free allows everything suspension related to move, couple this with some of the freeway conditions and realize that the Rancho rear shock set to a nine has tremendous resistance the loads are just really high.
I won't use the tie-down method as a reason not to take action and I haven't. I have crept up on it over the years. Trying to stay with highest levels of performance employing the least amount of weight we changed the design so that the area would have more structure, we tried gussets, material thickness. Our latest design seems to be working the best so far (early 07) with no reported problems since. Again, a vast majority of our customers will never have a problem even with the bars we manufactured in the mid ninety's. I do feel a discussion on tie down method would benefit many racers and not just because of this issue. All the suspension components and even the handling of lightweight tow rigs are affected by how the car is anchored.

Thanks for the info, forward this on if you like.
