I decided to try swapping my wheels between 306/307 just to see where the clearance issues are and how bad.
The 307 wheel appeared to clear on the N/S front of the 306 and I thought it was looking pretty hopeful. However, the N/S rear was able to turn but was rubbing the tyre on the end of the rear beam. I want to run the standard 307 tyres 205/55/16 until I have used up the tread on them and then may go for a lower profile, so I have ordered some 20mm spacers for the rear. Looking at the picture taken from behind, it needs spacing to fill the arch more anyway.
If you were to use a thinner tyre stretched onto the rim you may get away without spacers as it is the tyre that is rubbing on its inside edge, not the rim itself.
Regarding going the other way, the 14" steels won't go near the callipers on the 307 (discs on mine are 190mm) so I have ordered some 15" 307 steels through eBay which have ended up costing as much as buying another set of alloys or a scrap 307.
My car is at standard ride height, or maybe a bit lower due to age and mileage!
