I have a 91 XR2 and have added a front strut tower brace. This little upgrade has stiffened up the front of the car tremendously. The car stays level and has no more body roll. Remember, this car was made marketed as a true sports car. Thus, the potential of this car is limited. It's not like the Miata (by the way, I hate Miatas but you can't argue with success, either on the sales floor or on the track).
