If F104 response much faster at corners due to the new front arms structure, why people will like ...
Simply need lots of patient and testing, it is a harder car to set up, and drive i think. So for quick fun, 103 or 104W (104 with 103 front arms), is better. I have 104 and 104w, 104wis more relax to drive. Thus many can go faster with 103 or 104w.
