Now constructing their own cars for 1986, Spice also expanded to the IMSA GT Championship, where they assisted in the running of Pontiac's Camel Lights competitor. Meanwhile, in the WSC, Spice would score another two victories, yet miss out on a repeat of the team's championship to Ecurie Ecosse. Spice would return to form in 1987, with seven victories and retaking the championship. Spice would expand on this even more in 1988, when in an eleven race season, they failed to win their class only once, thus earning them a third championship title.
