My old man just went out and measured it and informs me that the diameter goes from 28.02 to 27.90 depending on where its measured (he is a fairly accurate and thorough sort of chap, lol)

So sounds like you are right with the 28mm Matt.

Where can I get some in a hurry, MOT retest is booked for Friday midday.



Edit, slight misunderstanding, he measured the front one as I just said "the antiroll bar" without mentioning which end, oops!

I will send him back out to measure the rear now
