The most important factor in stopping the "nodding dog" syndrome is, as PJB has proved, to have the lower rebound spring unloaded at static (road ready load) ride height. The adjuster is to insure that this condition may be acheived regardless of the differing weight of the various engine configurations.

The Suplex kit is supplied with a 20mm spacer to set the ride height in one of two positions but my car now uses a series of shims to set the height and now has 10mm above and 10mm below the axle. Any spacers could be used to set the ride height as long as the total is the designed 20mm.

If someone wants a firmer front end the lowest rate spring from the Suplex race kit can be fitted. Contact Suplex for details.

I should also add that the Suplex/Peter Ballard design is oriented towards a comfortable ride whilst maintaining good handling. This is why the initial spring rate is lower than that of the Mulfab springs and it is also why there is a second "rising rate" spring to stiffen up the suspension in extreme bump situations. Roll control is assisted by the lower rebound springs which a very stiff and help to minimise the lift in the suspension of the car on the inside whilst cornering.

The Suplex race kit is obviously oriented more towards sharp handling on a race track and comes with a set of higher rate springs that allows the car to be set up to the requirements of the driver.

I can't comment on the Mulfab kit as I have never used it but I can see that any correctly set up front spring would be better than that fitted to some of the older Morgans. There are many owners on this forum that are very happy with the Mulfab setup.

It must be said that the new Morgans are much improved in this respect by comparison to the setup they supplied with my car only 4 years ago.
