Not the best pic but you can see my rear shackle is basically straight up and down. I searched and read a bunch on shackle angles and it seems like it should be pointed backwards a bit more. Will going to longer shackles (say 5 or 6") help with this or is it ok as is? I don't really want to lift it any more though (already at about 6"). I was planning on getting the DIY shackles anyway, so if i need to go longer, now would be a good time... thanks!
