damn et11, i think that won't work with spacers.

option 2:
make new holes in the wheels.
take a center ring that will fitt in the bbs wheels and take a 20mm spacer 4x100 that will fitt in the inside of the center ring.
take a drill and make 4 new holes.

but first put the 9x16 against the brake..., so you kan see if it is realy going to fitt before drilling new holes.

i hope you understand what i'm saying.
