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

If the suspension was sagging would the distance from the top of the wheels to the bottom wheel arch also drop?

Yes Mike you are right

Sorry I tapped the wrong key!
The measurement that manufacturers use is the distance from under the wheel arch to the top of the wheel or the centre of the wheel. The Plus Six is presently at the garage having the SSL coil over damper units fitted and the first thing my mechanic asked me was what were the figures Morgan had given for that clearance rather than the ground clearance. I don't have a clue!.

And that's the measurement you need...

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!

I have just measured my Plus Six, registered March 2020 4k miles

Front both sides 660mm

rear left 680mm

rear right 675mm

It would be interesting to see what other UK owners measurements are.

My Plus Four MY2022 only has 80mm between the silencer and the ground with 635-640mm ground to wheel arch, 28psi in tyres. Should I be worried? Is the suspension design the same for Plus Four and Plus Six?

Great report NZPlusSix

I have:
Rear 640 / 650
Front 660 / 655
18” speedster wheels

Mike
What ground clearance have you got from the flat surface on the chassis adjacent the wishbone attachment point (where the Morgan jacking hole is located) to the ground Front? rear?
