I love the rostyles. However i reckon they look much better on a mk1 escort.
Large minilites look great on the capri and allow for bigger brakes.
I also love the 15 inch rostyles from image wheels and am tempted to buy a set.
The 205 will fit on the 5.5 rims but the sidewalls will come close to the strut. Its probably a case of fit it and see.
