Perhaps that was a bad point, but you can say that suspension travel that isn't OEM could exacerbate any failures. Also, who installed the part? Is it a certified mechanic?
Let me add, I have modified MANY, MANY of my cars. Changed out suspension on almost all of them up into the last few years (getting older, different priorities). I have gone as far as removing the entire engine block to get the block resleeved, titanium rods, port polish the heads, new cams, valves, valve springs, etc.. My disclaimer is I am not anti-mod, I just understand the risks that come with it.
