Clio b wheels 15 or 16 inches ?

Hi all on the one hand … for my new clio b ph 1 I am still looking for a few rims for the summer ….. first I thought of oz rallye-racing ….in 7 x 15 but they are no longer available. but now I just don’t know if it can’t be 16 inches, with about 110 ps I actually have just so sufficient power for 16 inches, but with 15s the whole of course a little splashy ….. only the large wheelhouses are then so empty …. a little deeper ( 30-40 mm) he is yes already. who has 15 and or 16 inches on the clio b and has optical tips car is black, initial 1.6 16v have you noticed clear differences in mounting the 16 inches?
