I am 5'9" but my Best Friend is 6'4" and he fits fairly snug but comfortably in my R. HOWEVER, in my Sister's LS his head is nearly out of the Sunroof LOL. The Stock R seats sit lower than the LS and GSR seats. Notsure if it is the seats them self or if it's different rails. Now there are plenty of Lower position seat rails out there. I wouldn't say scrap the R idea for that reason. Best thing to do is just Test drive one.
