I'm with rcr on this one. Not optimum for a track car but if you drive in the real world certainly piece of mind. If I decide to run on the track a second set of wheels and track only tires would be a simple solution. Run flats are a planned upgrade for highway use but I really would rather have spent the money on something else.

I seem to average a puncture every year or two, Some have been such that no way would a can of goop fix it. Ever hit the remaining hook of one of those cheap rubber bungees? They disguise themselves very well as a tar patch on the pavement. The gash they leave won't be fixed by goop. So your walking. In some areas without cell coverage a long way to find it. Something I suspect the Porsche engineer never got far enough from his workstation to think about. I work with folks like this. Most times reality surprises (shocks) them.
