I personally have 2-Door Integra Type R rear seats.

The upper pieces fit 100% like factory. The bottoms do not. They just sit there and cannot be bolted down. There is also a gap on the sides about 1.5-2inchs. It's not that bad honestly.

However. You can use the JDM ITR 4-Door seats. You CANNOT use the upper portions of these, you can sell them to someone though. The bottoms fit 100% like stock in junction with the 2-door upper seats.

So. 2-Door ITR Upper back seats. 4-Door ITR lower back seats = factory looking Type R seats.

If you have any more questions let me know.
