The adapter plate type: problems I foresee - You would need to ensure that existing studs finish flush with the face of the plate, otherwise the wheel will not sit on the machined face, so the wheel arch needs to accommodate something like a 40mm spacer, anything less and the existing studs would need shortening. The OD of the raised centre piece has to be compatible with the centre hole of the wheel. New nuts will be needed to locate the adapter plate and the wheels to the adapter. Or change the bolts so existing wheel nuts can be utilised.

Not a straightforward 5 minute job as most options require modified studs and the removal of the rear hub.

A fatter tyre helps fill the arch. I have 235/70/15 on standard rims on the rear.

I would suggest modest spacers are not a danger, as they remain freely on sale.

No experience of Insurer's views on spacers, but having read horror stories about them refusing to pay out for the flimsiest of reasons, I always make a point of declaring wider tyres, which has yet to cause any comment.

Would you be good enough to post pictures of your 603 wearing 205 and 235 tyres so that we can see the difference in appearance?
