Remember, the only thing connecting your car to the road are your tires ... not the place to save money. Not just blow out or tread separation, good tires will give you the best chances in an emergency maneuver as well.
Yes, I had to buy new tires for the 993 ... that made me just go with R888 for everyday driving + the occasional track event. No more designated sets of wheels. They won't get old on me in 6 years!
