Clarke the charts have not been in use since mot computerisation 5 years +
Rs turbos were on the chart, along with a lot of other random cars, certain automatics cvt type iirc. But as the vts now tells you in the vsi about any abnormalities with the brake test the charts are not needed, note that the vsi always reads STANDARD vehicles of this typr may be tested using a rbt.
Also not every roller brake tester has the 4x4 option

-60mm Drop i reckon would catch, my Orion is -40mm which is -30mm for a turbo and that catches the mudflaps when in the rollers and on the beam jack on the mot ramp! Still you can't have standard ride height can you!?
Agan not every testing station has rollers with these options.
If in doubt get the deceloremetre on the job.
My cabrio gets this, I just ask for it not to go in the rollers.
