Interesting review here of the Porsche 911 Targa 4. Enjoy!
Speaking of the track, the Sanair Complex is not renowned for its clean surfaces and smooth stretches. In most situations, the Targa did little but cope with the changing tarmac conditions but, on a few occasions where rapid-fire switchbacks were on the menu, the car became somewhat twitchy. This is not unusual for the rear-engined car, however, and as a side-note, the Volkswagen GTI I was also tracking displayed none of these characteristics.
Calabogie is a very different track where stretches are short and corners are never-ending. The Targa’s rear-weight bias was constantly kept in-check so long as throttle modulation remained linear. Nowhere on this circuit did the 911 have the shakes, but it could never match the prowess of the Boxster Spyder that I also tracked on the same day.
