The only REAL benefit from the RSX/SI(R) seats is the shoulder support. Those seats will hug you a bit more.

The RA seats aren't as supportive as my RSX seats were. My shoulders over hang the RA's seats by about 2in. each side....so that would be MY reason for getting some better seats.

Having said that...aside from them not being leather...these are better seats then my dads Audi.
