Is there any way i can convert my RA40 to ford/commodore stud pattern? I want to run 15" steel "chasers" (widened to 7") on it as im building on a budget but still want a "tough" looking car. Any help would be appreciated. P.S. does anyone know if nissan etc. had a 4stud 15 inch steel rim (early skylines maybee??) Thanx, chris
