The seats are OEM seats out of an Evo 10 so I'm not sure what you mean by DD annoyance, I think they're very comfortable. They recline, and slide forward and back with no issues on the RX-7 rails. As far as rubbing, they are VERY close to rubbing, but dont. On the passenger side I can slide 2 stacked credit cards between the gap without touching and there is no rubbing at all. On the drivers side you can only slide a few sheets of paper between the bolster and the door. The center of seat is 1/4 off from center of steering wheel. It's not noticeable when driving. There are no rubbing, squeaking, creaking issues.
Also the seats are about 1/2 lower than the OEM seats which is great for a little extra helmet room.
I'm 5'6 and sit comfortably in the car, and my friend is 6'3 280ish and he sits comfortably as well. There's plenty of leg room on the drivers side with the seat slid all the way back.
