If you have the vented rotors you should be able to make the D90 calipers work. Although, you would need to get some T's and plumb the 2 brake lines into 1. to make them work. So short answer is, it's not as easy of an upgrade for an RRC. I'm not sure if the '95 RRC's were any different since they had more in common with the DI's.
