They should be pretty much the same exept for the rear disc brakes, which add a lot to looks. Anyway, the "sportier" suspension settings would change if you put some Eibachs on your GLS, and I bet it would be even more agressive than a stock GT. Add wheels and sportier tires, and there you go with a sporty GLS.
