How much in general should going from standard Subaru 16 - 17" wheels be extra on a premium. I know it depends on the insurer, as some won't charge, some will, but whats the average increase on insurers who would? I'm with Churchill atm, tia.

Mine wanted £140 on a £1100 policy to go from standard 16's to aftermarket 17's.

i went frm standard 15's to 17 superleggras and they stuck £100 a year on with norwich union
