I'm kinda wondering why you'd want to add weight to the front? But i would not drill the hub,maybe the iner rim,a lot of larger rims have 4 holes for that reason. but the 2310 has darn small front rims for much useable weight. have you thought of a bracket off the frame some how to add and remove suitcase wheights,something you could bolt on exsisting holes. Assuming you want the loader on,if you want to have weight with it off just get the front weights. Just something to think about! Every thing we do is somthing to think about ain't it lol!
