The most I’ve ever done is 115mph in two different cars - a 1985 Nissan 300ZX and a 1991 Mazda Miata.
The Z was a bit spooky at those speeds. The front end got really light once I got above 100.
The Miata had absolutely no more to give once I got it to 115, but it was dead stable at that speed. Which surprised me, given its light weight and short wheelbase.
that is surprising about the Miata. i loved reading your experience with the two cars. it sounded exactly like you were talking about horses :). after all we are talking horse power here comparatively. nice write up though. glad it was a safe excursion both times.
