The needle quickly hit 120 mph but wouldn’t move any further because at the bottom of the speedometer, there is a knob that resets the trip counter. The needle kept bobbing up and down resting on this knob. So I really don’t know how fast my CRX was doing beyond 120 mph.
Surprisingly, it was very stable and controllable even at that speed. There were no unwanted vibrations or twitching of any kind. It felt very well planted. Fyi, I have all-season tires, and stock suspension set-up. Only thing non-stock is the Energy Suspension Polyurethane bushing set.

I remember I wasn’t as comfortable even in my S2000 doing about 130 mph. Largely because the noise from the roof was unbearably loud. The roof on the S2000 starts to flap uncontrollably at about 120 mph. The noise and the vibration in the cabin is enough to make your head hurt after few minutes. Anyway, man, this little CRX is such a joy to drive. I couldn’t ask for anything more from this car.
