Tech question, 88 GT 440hp 500ft/lbs of torq

I need some feedback on what changes you would make to the suspension on my GT so that it will handle some of the power. Right now its stock, I enjoy driving it on the street and want to keep some of the handling but I also want to get as much of the power as I can to the ground when running in a straight line.

I have some ideas but would like to hear what all of you think?

Thanks
