Yes, I have checked.
The potential confusion is that at least one respected source suggests that there was an increase in diameter for the softer suspension, and that at the end (85th) that the bar was thicker still. That same source suggests that there was a 2mm difference between one bar and the next.
It is fairly certain that the thickest was 25mm.
One dimension (recorded in the manual) is noted to be 20mm, but that doesn’t say whether that is the thinner or the thicker two.

I need to renew the struts or at least the springs to resolve the ride height that is way too low.
It is my belief that the PO fitted the comfort pack springs (or some with a similar rate but not necessarily the same free length or possibly same rate but shorter).
Clearly the PO changed the springs - that is obvious- what is not known is what was done to the anti roll bar.
A rough check over the PU coating suggests that diameter is 20mm. That suggests the actual bar might be marginally thinner than 20mm or the bar is a nominal 20mm.
Common sense suggests that if the original springs are re fitted then the first (smaller diameter) bar needs to be fitted otherwise it will be too stiff. Hence the need for clarity.
