On my Monaro i changed the front rims to 7" and the rear to 8", painted the rims in cyan blue, with the wider chrome insert trims and the original centre hubs i painted blue as well. Later on i put a set of HQ GTS rims on the car, the ones with the 5 spokes, which only came in at 6" wide, so i had the whole centre hub removed from the rims, and had them re-fitted into new 7" and 8" steel rims, and had them painted exactly like this photo below, only i did the black bits in cyan blue. The outer 2" and 3" wide lip i also painted blue, and i re-fitted my 2" and 3" chrome trim rings from my previous rims on these rims as well, looked really nice. A lot of GTS owners removed the centre hubs and had them fitted into wider Chrome rims, but it didn't look as nice as mine i don't think. Wish i had photos of that car, looked really nice.
