I have the suplex set up on the front lf my plus 4 and sourced matching bilstein shockers for the rear so i have bilstein all round. The standard rear leaf spring set up on the back much improved the ride quality after i gave the rear springs a severe lubricating. It took a while and a few hundred miles to achieve the improvement. Lubricating the rear springs was something that i overlooked, the cars clearly leave the factory un-lubricated. I can actually feel the increase in compliance when i did a before and after press on the rear end to check the bouncability. I think ive gone as far as i am prepared to in order to improve things in this department apart increasing the tyre profile when new rubber is due.
I agree. In a conversation with Peter Mulberry about 10 years ago, Peter told Me that cleaning and lubricating the rear springs is the single most important item to address for a more compliant ride in a Morgan. I did this and I feel I have about as compliant ride as obtainable in a Morgan. I now spray chain oil on the top of the spring and it works itself in between the leafs. Last year I took the spring apart to insure it was getting lubrication properly. It was!
On My 650 mile trip to Sun Valley and back to Seattle I took separate routes with many different road beds. It was easy for Me to determine that it was the quality of road that is causing the uncomfortable ride. As was stated there is just so much one can do with Morgan suspension..
