New MINI what Class?

[Lowerit]

Just bought a new MINI (needed a new autocross car while mine is being finished) Not an S, has the sport suspension upgrade , 16" wheels. Bone stock. Just wondering what class it runs in? I actually bought it for my girlfriend with the understanding that I get to autocross it :)

thanks

Looks like the non S mini is classed in B1,the S is in BSS with 2 prep points.
