| load on the bump compared to the normal system, but not so much load on the bump as when you tried the car. On the re-bound the load also increases from that of the normal system. Thus this leverage gives a fairly high rate on the bump and a very low rate on the re-bound. Dubonnet will also draw and make a set of levers giving a less variable rating system for both bump and rebound than the present system. These will take about 10 days to make, so he will bring them to England when he comes on December 10th. I hope therefore to return to England with the car at the end of this week. | ||
