At this weekend I tried the Bridgestones. I got head shake every time I went over the transition pulling onto the front straight. While at the trackday a month or so ago I had pirelli on. I did not get the shakety shake. Did any one else notice this that was using Bridgestones? Crispy
Most likely, this is not something inherent to Bridgestones. Different tires will sometimes require a different setup; also, the tires not being balanced properly could do this.
I tried Bridgestones for the first time this weekend too. I only got a little headshake on the back straight. I figured it was just the front end getting light and that hard transition.
