Which series can BMW Minis race in?

[PR1]

Does anyone know of any series or one off races for a Supercharged Cooper S in 'Mini Challenge' spec?
I'm aware of the following already:
www.minichallenge.co.uk
750MC Birkett relay
BRDC Eight Clubs
Britcar (inc. Willhire 24hrs)


[Our Mini can't do 750MC Hot Hatch champ 'cos doesn't allow forced induction]

Any Web addresses for the series you know of would also be good...
