 A stopgap solution to the flexing problems was to weld extra tubes around the cockpit of the Mk4.When the revised Mk4A was introduced its most significant difference was in a number of body panels that were welded to the chassis in what Lola described as a "semi-monocoque" design.With the uprated designs results continued to trickle in, but a lack of development funding stunted the cars competitive growth, and by the end of the season both the Mk4 and 4A were completely outclassed.
