I added the repeaters, I like the look and the extra function to let dumb drivers know I am going to turn. It helps stand out a lot, expecially at night. I got the clears instead of the smoked ones to help w/ the contrast. There are ones for the e30 that are slightly larger than mine, mine are off a e36/34...
The e36 ones are more slim than the taller e30 ones.
