I would like to fit the later 4.5inch wires to my Mk 1 BMC suspension
Turner with Disc brakes. The problem is the bigger wheel fouls the
steering arms. Is it safe to put a 12mm spacer between the wire mount
and its mounting platform? The inside edge of the wheel will then be in
the same place as with the smaller wheel so I would imagine the forces
would not be that much greater.
