I'm pretty sure the SM bar are not really much lower than stock, and if they are, then maybe risers?
I think LSL have a number of difference bars with differing rise and taper, just don't where to get them here, so it might be trial and error from the states?

btw, I think these are 7/8" bars, you might have to look into the fat bar option..
