I have a LWB T32 Kombi. I run 275/40 19s, which are virtually identical rolling radius as the VW supplied optional extras of
275/35 20s.
Early on I had H&R load rated -50mm springs fitted.
My standard wheel centre to arch heights were 460F & 470R.
After the -50mm springs fitted they were
405F & 420R.
Since then I’ve fitted seat base swivels and have an IKEA Hammarn sofa bed in the back etc.
Probably carrying 50kg in total.
Heights settled down to 400F & 410R.
Latest addition is Koni Special Short struts and shocks from
@CRS Performance .
Heights now down to 390F & ~400R.
So, actually down 70mm front and rear although only very, very lightly loaded!
