So many hot rod shops don't install proper bump stops.  In this instance we had to rebuild the shocker mounts on the diff as the rear end was bottoming out on the shocker travel becasue it had no properly designed bump stops in place. So the shock absorber mounting bracket was absorbing every bump when the suspension bottomed out, easy to see why both mounts broke. While we were repairing the diff I made a simple yet effective progressive bump stop that is held in place via the U bolts that hold the diff to the leaf springs. It turned out a very successful set up. This is yet another example how Kustom Bitz can sort out problems on your custom car or hot rod, its what we do.

Back in the day Group C racing one of the tricks to get the Holden Torana to handle nice and be more predictable in corners was to fit a rear pan hard bar to give much better diff locating than the OEM triangulated 4 bars offered.  However the body, subframe and floor pan at the rear is no where near strong enoungh to concentrate the loads of pan hard bar in any one spot, so it has to be carefully planned and constructed, especially so in a street car like this that we cannot put a full roll cage in. You see in a race car I can place the roll cage in a position to pick up such loads placed on the pan hard bar brackets, but in this situaton we couldn't. The picture above is with the unit installed, keep in mind the car was just a shell so no weight was in it and the rear is sitting high. Once the full wieght of the car is on, it will sit fairly level.  It retains the original triangulated 4 bars however we run PU bushes in the bottom arms and ordinary rubber in the top arms. So the lower arms and pan hard bar do the locating and the top arms have some give so they don't bind with the pan hard bar.
