Hi what size wheels are these and tyre profile please. I’ve got a 55mm drop front and 40mm rear on standard 16” Claytons but I want to change to 20” if possible. Thanks

Is there a reason you run the van like that ?? Intrigued ! Do you load it a lot ?

I don’t quite understand your question? I see you are a suspension specialist so please enlighten me in what I’m doing wrong
As for the load I’m a plumber so I wouldn’t say it’s loaded? The usual tools and materials.

Hi Ya a correctly set up van should have the same height front to back ( centre of the wheel to top of the arch ) if this is level then the van chassis is actually 40 mm lower in front than the rear . these measurements are done on the Sill.

There for 55 at the rear and 40 at the front will give a rake forward of 55 mm instead of 40 ???

Sorry for the thread resurection.
OP - what did you end up going for?

I'd like to drop mine (also has 20" wheels) but unsure by what mm.

@J88arv - My bus is exactly the same as yours

Also, should the wheel alighnment be done stright away or after they've settled?

Geometry should always be carried out after any suspension work, and because of the state of our roads, we now recommend every 6 months. We alway carry out a roadiest then carry out a full Hunter - There is no settling in period
