Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Plus Six Ground Clearance

Our replacement coil over damper suspension units with adjustable spring platforms for the Plus Six arrived safely in NZ and have been fitted.

Firstly a big shout out to Dan and Peter at SSL for their professional advice and guidance, plus a heap of patience they had answering al our questions! Well done chaps.

Our Plus Six ground to wheel arch rim measurements with the new suspension units, on level ground, full tank of fuel, un-laden & 28 psi in tires. And after being driven and settled overnight.

It is such an easy way of measuring how high your car is off the ground and I would recommend all Plus Six owners with any concerns to measure their cars and compare with our car.

Also the ground clearances are now virtually the same as Williams got from Morgan before I ordered the Plus Six 135mm front; 155mm rear. That is measured on the flat surface on the chassis adjacent the wishbone attachment point (where the Morgan jacking hole is located). My P6 130mm front; 150mm rear. The minimum ground clearance under the muffler is now 105mm

Another noticeable change was that with the dropped suspension the toe-in had changed and the car tended to wander a little on straight roads. With lifted suspension the toe-in was now back to what it should have been.

I'm waiting for the brake unit replacement before I do a real road test on windy mountain roads so watch this space!

A GREAT car just made better!

Given the side to side (right to left) variations in ground to wheel arch heights I’m getting from other P6 owners we could find some of it being due to hand assembly of our Plus Six especially the front wings. Also tire pressures could make a difference. We are using 28psi all round as the standard.

The 130mm measurement was that at the jack location flat plate adjacent the lower wishbone attachment point? Was this measurement at the rear? If so what was the front measurements – right and left? The ideal, should be 135mm front; 155mm rear, plus or minus 5%.

I'm presently building a table of all the measurements owners are supplying via TM.

Also a bit worrying that Plus Four owners are now reporting loss of ride height when it was thought that they had escaped this problem.

If you have ever replaced old tyres on a Morgan you will be amazed at the difference.
