My B44.1 is too fat

[RobW]

Went to run yellow mini-pins yesterday at Mid South regional and the car was too wide to fit in the box. I'm not talking a bit tight - the rear would not fit in the box. Car is kit standard on rear toe-in with about 1 degree of camber.

I know mini-pins are are a bit wider than most tyres because of the overhang and there were issues at our 2WD regional that were dealt with in a sensible manner but I do not want to turn up to the 4WD regional at DMS indoors with a car that I know is illegal on the tyres I expect to run.

Does anyone have any tricks for dealing with these (different wheels, narrower hex??) or else I'll have to work out what ballastics compound to run as they do not seem to have the same amount of overhang.

Cheers

Rob
