bought the post 2 weeks ago love it, changed frame thinking it it would just be a case of getting a shim - big mistake, it seems that you cannot buy a 30.9 -31.6 shim as the space is to small , with the exception of using a coke can, which i really dont want to do as its a dropper post does any one have any suggestions?
Buy a new frame
you can - i have one at home you can have for £3
You can't buy one IIRC but you can get the metal sheet to do it.

Contact Superstar they might be able to sell you a larger body for it as the shaft size might be the same.
USE sell them for £7 IIRC.
as i said - have got one!! A USE one you can have for £3
RR if the OP doesnt take it I will! Email in profile.
.. you could sell the seatpost and buy another (if they do the other size).
