What makes 911's so special is their ability to do this lap after lap, day after day, week after week and year after year within regular service intervals and at the same level of performance. Many people forget that Porsche track history comes from building bullet proof track specials that will do what they do for 10 years, hell even 20 years without needing much more than pads, disks and some oil changes, maybe the odd LSD and shocker. No caveats, no warranty issues, does what it says on the tin, especially the GT versions over and over again without owners having to worry they have to visit the dealer after 2 laps.
