Gry.{Shadwell Grylls} and Les.{Ivan A. Leslie} on the morning of 21.4.31. tested 25-EX for jellying.

The car had low rating front springs, four sandwich front engine mounting, standard hydraulic dampers.

The test was to determine the effect of mounting a 4" dia. tube immediately in front of the radiator to increase its torsional stiffness.

No difference could be detected with and without this tube.
