are these alloys available in 17x7" in 5x110 pcd format (black alloys prefferably!)? will they fit my mk4 astra??

ive been to a few websites like performancealloys.com which say they will fit (when i search by car manufacturer and put in my cars age etc) but on a site like alloywheels.com it only lists that nut size in the 18" size... !

also, does anyone have any pics of these alloys on a mk4 astra?? :O
