I was driving from our MOG autocross event back to the hotel which was 20 miles away(I'll post photos later). I was going about 55 mph and down hill when I had to start to slow down for an intersection. As I was slowly, but firmly pressing the brakes the front end starting to shake violently so I had to let off the brakes and give a little gas. It seemed like there was a harmonic point in which the vibration would occur and perpetuate it. It occurred for what felt like 8 seconds, but was probably more like 4. Does anyone have any suggestions for what could fix this? Very scary.
I have a pretty original 1967 +4 four seater. Here is my drive home after the weekend at MOG43 for the DC Morgan Club.
