Another Drive

Took another drive this morning, this time up to Skyline. The suspension is perfect except how it handles impact bumps at low speed. At high speed impacts get absorbed perfectly. At low speed, some impacts cause cabin noise, which bothers me.

I felt no absolutely no lack of comfort aside from the interior noises. The whole way up to Skyline, there was no noise actually because the road is free of impact bumps. The cobblestones in downtown Saratoga are absorbed, and train tracks on De Anza are absorbed. So not every impact causes noises.

Overall I'm very happy with the suspension, it's almost exactly what I was looking for, maybe a little harder. I'm hoping goflat tires and shock break-in will make most of the noises go away.
