concept-R

Im wondering if one notices enough of a difference to warrant that type of expenditure.

IN looks, definitely, makes the car look sick. In function, unless you routinely track the car at 120mph+, I would really doubt it. I've never noted any real difference in the one on my FD. but, I don't track the car at high speeds either...I'll do an occasional interstate run to 140 or something, but that's about it.

i would imagine that the RE-A unit does make a considerable difference at high speeds. however, i think to get the full potential out of it you need a full aero package like intended by RE-A...
