If your that worried about performance sell the cali top and buy a non sunroot car. You will never make up the lost rigidity of the non sunroof chassis vs the cali top chassis. I would suspect you might even find someone who will trade even who WANTS the cali top badly, in my part of the country they carry about a 2K dollar premium over the other tops.
Just my .02 bucks worth.
