Im almost positive you can't just take any seats from honda/acura and they will bolt right up. LS seats are not leather, just cloth and not worth it IMO. If i were you, i would just get some GSR leather seats and call it a day! forget about the ITR.

Im not too sure about RSX seats, but they do however come with stock Recaro's. Either way, with that option, Recaro's are expensive no two-ways about it! GSR leather all the way bud.
