Ok try this then.
Type in 5 dots similar to this ..... The length of those 5 dots is 5 mm.

Going by the pics above my guesstimate is another 10mm (F) and about 15mm (R). I'm no expert re spacers but what would really help here is an accurate pic from above, in front and the rear EXACTLY in line with the fenders.

To be more precise you could put a large roofing square on the ground, push it gently against the top of the fender, in line with the centre of the wheel, then measure the distance back to the rims or moreso, the outer wall of the tyre.
