Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Plus four ground clearance

Anyone know what the ground clearance should be on a new Plus Four? What is the lowest point?

I think you will find in most jurisdictions it is 100mm at any underside point, i.e. You should be able to drive over a 100mm high block of wood.
In OZ, most formal inspection station "pits" have a 100mm lip. If you cant drive over it then the vehicle is failed.
On most Morgans, the lowest point is the cross member under the gearbox or the sump.
It might be a good idea to ask the Morgan dealer in your area.

I think I can guess why ….

Google “Morgan Plus 4 ground clearance” and you will get a lot of TM references to the subject.
Check the vehicle regulations in your jurisdiction then ask Morgan for confirmation that the vehicle complies.

The lowest point is now the exhaust at the rear . And as the suspension is soft i have already hit the ground two times. The height could be 10 cm but i will mesure later.

Wow Thierry, so the exhaust is lower than the cross member AND the sump on a new Plus 4.....

I think you need to review clearances in relation to where the wheels are. A low side pipe exiting in front of rear wheel(s) is unlikely to ground for example.

The floor is now competely flat ,but at the rear the four tubes coming out from the silencer are a bit low.

Mine had the u clamps fitted and the bolts would bottom out, so I change them to Mikalor Supra clamps.

It is 8 cm

There is a difference between the ground clearance on flat ground and what happens at either end when the gradient changes. You can hit a 9cm sleeping policeman with a 10cm ground clearance if the overhangs front and back of the wheels are flat.
