Andy, Thanks, I was hoping that they might soften the ride. I don't have any bottoming out issues with the Koni Classics currently fitted. The Bilsteins will go on the shopping list for early 2016.
Incidentally, I did a quick 80 miles this morning in the Plus 4 to Williams to pick up some parts and then to Terry Foxen at Nailsworth for some more bits for the '59 car. Weather much better than the past few days. Very enjoyable run up the A46.
