Will 16-inch wheels clear the brake calipers on my Peugeot 308 CC?

I asked you where I could purchase different size wheels for a Peugeot 308 CC TVi Allure to improve its ride. It is currently on 225/40 R18s. You suggested a set of four TUV-approved 16-inch Alutec wheels from www.tyremen.co.uk and a set of 205/55 R16 tyres, but my local Peugeot dealer spares man tells me that the downsize to 16-inch wheels is not possible due to the size of the brake calipers. He mentioned something about bigger calipers to counter the extra weight from strengthening the car for its opening roof.

I can understand where he is coming from, but not according to Peugeot, which lists the wheels and tyre sizes for the 308CC as follows: Izalco 7Jx16 alloy wheels – 215/55R16 tyres. Stromboli 7.5Jx17 alloy wheels – 225/45R17 tyres. Lincancabur 8Jx18 alloy wheels – 225/40R18 tyres. From: www.honestjohn.co.uk/carbycar/peugeot/308cc-2009/?...d
