Well the mods are done. Took them down to 22mm and it is a great success.
Let me set the scene - Stock Td5 D2. 235/75R16. (no lift).
Machined down to 22mm and screwed back in. No rubbing on the guard.
Things to note -
- larger tyres may pose an issue
- different number of turns centre to lock(2 right - 1.75left)
- don't stress it too much on full lock as CV joints will be under more stain
Thanks to Pedro the Swift and Urban Panzer for assistance.
