With a little luck I find time on Saturday and I can go to my son's hobby workshop. There is a lifting platform. Since the rebound limiting rubbers of the 4/4 are simply double layered, I can remove one of the two layers to try it out after doing a measure how it is now. I will follow Roger's advice to see if the damper limits the rebound or if it is long enough.
But...if the TB1260 shock is designed for the Roadster, then it should be long enough? The Roadster doesn't have a lowering block either? And the frame is about the same, I think? And the compression works fine, it is even less stressed now than with the LBs.
At least my sagged springs compensate a bit for the probably slightly heavier weight of the Roadster at the rear.
