I have a set of SPC upper A-arms that hit sections of the frame bracketry that holds them on. I have been doing some minor grinding to get some more travel out of the arms, but how much travel is normal? I didn't check with the old set up before I took it all apart so i have nothing to compare it to. It won't see a lot of street use but I don't want it to be air born every bump it hits either. If anyone has any tech articles or info on this would be greatly appreciated. Thanks
