2002 Alfa Romeo 147 GTA 1/10 scale RC wheel. Diameter: 52 mm. Width: 26 mm. 12 mm hex mounting. 4 mm center bore. 0 mm offset. Original wheel manufacturer: Speedline. This wheel has been meticulously and accurately modeled after the original wheel specifications and many detailed pictures. It's equipped with extra 1 mm wide ribs behind the spokes, for great strength and durability. You can remove these manually, but I suggest to paint them black if you don't like the look of them. This price is for one wheel. If you would like the wheel with a different offset: please let me know and I will make this with no extra charge.
